Python之所以应用越来越广泛,在一定程度上也依赖于其为程序员提供了大量的模块以供使用,如果想要使用模块,则需要导入。导入模块有一下几种方法:
import module from module.xx.xx import xx from module.xx.xx import xx as rename from module.xx.xx import *
导入模块其实就是告诉Python解释器去解释那个py文件
- 导入一个py文件,解释器解释该py文件
- 导入一个包,解释器解释该包下的 __init__.py 文件
那么问题来了,导入模块时是根据那个路径作为基准来进行的呢?即:sys.path
>>> import sys >>> print sys.path [‘‘, ‘C:\\WINDOWS\\SYSTEM32\\python27.zip‘, ‘d:\\Python27\\DLLs‘, ‘d:\\Python27\\lib‘, ‘d:\\Python27\\lib\\plat-win‘, ‘d:\\Python27\\lib\\lib-tk‘, ‘d:\\Python27‘, ‘d:\\Python27\\lib\\site-packages‘]
如果sys.path路径列表没有你想要的路径,可以通过 sys.path.append(‘路径‘) 添加。
通过os模块可以获取各种目录,例如:
import sys import os pre_path = os.path.abspath(‘../‘) sys.path.append(pre_path)
开源模块
下载安装有两种方式:
yum pip apt-get ...
下载源码 解压源码 进入目录 编译源码 python setup.py build 安装源码 python setup.py install
注:在使用源码安装时,需要使用到gcc编译和python开发环境,所以,需要先执行:
yum install gcc yum install python-devel 或 apt-get python-dev
安装成功后,模块会自动安装到 sys.path 中的某个目录中,如:
/usr/lib/python2.7/site-packages/
二、导入模块
同自定义模块中导入的方式
三、模块 paramiko
paramiko是一个用于做远程控制的模块,使用该模块可以对远程服务器进行命令或文件操作,值得一说的是,fabric和ansible内部的远程管理就是使用的paramiko来现实。
1、下载安装
# pycrypto,由于 paramiko 模块内部依赖pycrypto,所以先下载安装pycrypto
# 下载安装 pycrypto
wget http://files.cnblogs.com/files/ryan/pycrypto-2.6.1.tar.gz tar -xvf pycrypto-2.6.1.tar.gz cd pycrypto-2.6.1 python setup.py build python setup.py install
# 进入python环境,导入Crypto检查是否安装成功
# 下载安装 paramiko
wget http://files.cnblogs.com/files/ryan/paramiko-1.10.1.tar.gz tar -xvf paramiko-1.10.1.tar.gz cd paramiko-1.10.1 python setup.py build python setup.py install
# 进入python环境,导入paramiko检查是否安装成功
2、使用模块
#!/usr/bin/env python #coding:utf-8 import paramiko ssh = paramiko.SSHClient() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect(‘192.168.1.108‘, 22, ‘alex‘, ‘123‘) stdin, stdout, stderr = ssh.exec_command(‘df‘) print stdout.read() ssh.close();
import paramiko private_key_path = ‘/home/auto/.ssh/id_rsa‘ key = paramiko.RSAKey.from_private_key_file(private_key_path) ssh = paramiko.SSHClient() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect(‘主机名 ‘, 端口, ‘用户名‘, key) stdin, stdout, stderr = ssh.exec_command(‘df‘) print stdout.read() ssh.close()
执行命令 - 过密钥链接服务器
import os,sys import paramiko t = paramiko.Transport((‘182.92.219.86‘,22)) t.connect(username=‘ryan‘,password=‘123‘) sftp = paramiko.SFTPClient.from_transport(t) sftp.put(‘/tmp/test.py‘,‘/tmp/test.py‘) t.close()
import os,sys import paramiko t = paramiko.Transport((‘182.92.219.86‘,22)) t.connect(username=‘ryan‘,password=‘123‘) sftp = paramiko.SFTPClient.from_transport(t) sftp.get(‘/tmp/test.py‘,‘/tmp/test2.py‘) t.close()
上传或者下载文件 - 通过用户名和密码
import paramiko pravie_key_path = ‘/home/auto/.ssh/id_rsa‘ key = paramiko.RSAKey.from_private_key_file(pravie_key_path) t = paramiko.Transport((‘182.92.219.86‘,22)) t.connect(username=‘ryan‘,pkey=key) sftp = paramiko.SFTPClient.from_transport(t) sftp.put(‘/tmp/test3.py‘,‘/tmp/test3.py‘) t.close()
import paramiko pravie_key_path = ‘/home/auto/.ssh/id_rsa‘ key = paramiko.RSAKey.from_private_key_file(pravie_key_path) t = paramiko.Transport((‘182.92.219.86‘,22)) t.connect(username=‘ryan‘,pkey=key) sftp = paramiko.SFTPClient.from_transport(t) sftp.get(‘/tmp/test3.py‘,‘/tmp/test4.py‘) t.close()
上传或下载文件 - 通过密钥
内置模块
一、os
用于提供系统级别的操作 os.getcwd() 获取当前工作目录,即当前python脚本工作的目录路径 os.chdir("dirname") 改变当前脚本工作目录;相当于shell下cd os.curdir 返回当前目录: (‘.‘) os.pardir 获取当前目录的父目录字符串名:(‘..‘) os.makedirs(‘dirname1/dirname2‘) 可生成多层递归目录 os.removedirs(‘dirname1‘) 若目录为空,则删除,并递归到上一级目录,如若也为空,则删除,依此类推 os.mkdir(‘dirname‘) 生成单级目录;相当于shell中mkdir dirname os.rmdir(‘dirname‘) 删除单级空目录,若目录不为空则无法删除,报错;相当于shell中rmdir dirname os.listdir(‘dirname‘) 列出指定目录下的所有文件和子目录,包括隐藏文件,并以列表方式打印 os.remove() 删除一个文件 os.rename("oldname","newname") 重命名文件/目录 os.stat(‘path/filename‘) 获取文件/目录信息 os.sep 输出操作系统特定的路径分隔符,win下为"\\",Linux下为"/" os.linesep 输出当前平台使用的行终止符,win下为"\t\n",Linux下为"\n" os.pathsep 输出用于分割文件路径的字符串 os.name 输出字符串指示当前使用平台。win->‘nt‘; Linux->‘posix‘ os.system("bash command") 运行shell命令,直接显示 os.environ 获取系统环境变量 os.path.abspath(path) 返回path规范化的绝对路径 os.path.split(path) 将path分割成目录和文件名二元组返回 os.path.dirname(path) 返回path的目录。其实就是os.path.split(path)的第一个元素 os.path.basename(path) 返回path最后的文件名。如何path以/或\结尾,那么就会返回空值。即os.path.split(path)的第二个元素 os.path.exists(path) 如果path存在,返回True;如果path不存在,返回False os.path.isabs(path) 如果path是绝对路径,返回True os.path.isfile(path) 如果path是一个存在的文件,返回True。否则返回False os.path.isdir(path) 如果path是一个存在的目录,则返回True。否则返回False os.path.join(path1[, path2[, ...]]) 将多个路径组合后返回,第一个绝对路径之前的参数将被忽略 os.path.getatime(path) 返回path所指向的文件或者目录的最后存取时间 os.path.getmtime(path) 返回path所指向的文件或者目录的最后修改时间
二、sys
用于提供对解释器相关的操作
sys.argv 命令行参数List,第一个元素是程序本身路径 sys.exit(n) 退出程序,正常退出时exit(0) sys.version 获取Python解释程序的版本信息 sys.maxint 最大的Int值 sys.path 返回模块的搜索路径,初始化时使用PYTHONPATH环境变量的值 sys.platform 返回操作系统平台名称 sys.stdout.write(‘please:‘) val = sys.stdin.readline()[:-1]
三、hashlib
用于加密相关的操作,代替了md5模块和sha模块,主要提供 SHA1, SHA224, SHA256, SHA384, SHA512 ,MD5 算法
import
hashlib
# ######## md5 ########
hash
=
hashlib.md5()
hash
.update(
‘admin‘
)
print
hash
.hexdigest()
# ######## sha1 ########
hash
=
hashlib.sha1()
hash
.update(
‘admin‘
)
print
hash
.hexdigest()
# ######## sha256 ########
hash
=
hashlib.sha256()
hash
.update(
‘admin‘
)
print
hash
.hexdigest()
# ######## sha384 ########
hash
=
hashlib.sha384()
hash
.update(
‘admin‘
)
print
hash
.hexdigest()
# ######## sha512 ########
hash
=
hashlib.sha512()
hash
.update(
‘admin‘
)
print
hash
.hexdigest()
以上加密算法虽然依然非常厉害,但时候存在缺陷,即:通过撞库可以反解。所以,有必要对加密算法中添加自定义key再来做加密。
import
hashlib
# ######## md5 ########
hash
=
hashlib.md5(
‘898oaFs09f‘
)
hash
.update(
‘admin‘
)
print
hash
.hexdigest()
还不够吊?python 还有一个 hmac 模块,它内部对我们创建 key 和 内容 再进行处理然后再加密
import hmac h = hmac.new(‘wueiqi‘) h.update(‘hellowo‘) print h.hexdigest() 不能再牛逼了!!!
四、json 和 pickle
用于序列化的两个模块
- json,用于字符串 和 python数据类型间进行转换
- pickle,用于python特有的类型 和 python的数据类型间进行转换
Json模块提供了四个功能:dumps、dump、loads、load
pickle模块提供了四个功能:dumps、dump、loads、load
>>> import pickle >>> data = {‘k1‘:123,‘k2‘:‘Hello‘}
#pickle.dumps将数据通过特殊的形式转换为只有python语言人事id字符串
>>> p_str = pickle.dumps(data) >>> print p_str (dp0 S‘k2‘ p1 S‘Hello‘ p2 sS‘k1‘ p3 I123 s. >>>
#pickle.dump将数据通过特殊的形式转换为只有Python语言认识的字符串,并写入文件
>>> with open(‘/server/scripts/day005/result.pk‘,‘w‘) as fp: ... pickle.dump(data,fp) ...
import json
#json.dumps 将数据通过特殊的形式转换为所有程序语言都认识的字符串
>>> import json >>> j_str = json.dumps(data) >>> print j_str {"k2": "Hello", "k1": 123} >>>
#json.dump将数据通过特殊的形式转换为所有程序语言都能认识的字符串,并写入文件
>>> with open(‘/server/scripts/day005/result.json‘,‘w‘) as fp: ... json.dump(data,fp) ... >>>
五、执行系统命令
可以执行shell命令的相关模块和函数有:
- os.system
- os.spawn*
- os.popen* --废弃
- popen2.* --废弃
- commands.* --废弃,3.x中被移除
import commands result = commands.getoutput(‘cmd‘) result = commands.getstatus(‘cmd‘) result = commands.getstatusoutput(‘cmd‘
以上执行shell命令的相关的模块和函数的功能均在 subprocess 模块中实现,并提供了更丰富的功能。
call
执行命令,返回状态码
执行命令,如果执行状态码是 0 ,则返回0,否则抛异常
ret =subprocess.check_call(["ls", "-l"]) ret =subprocess.check_call("exit 1", shell=True)
shell = True ,允许 shell 命令是字符串形式
check_call
执行命令,如果状态码是 0 ,则返回执行结果,否则抛异常
subprocess.check_output(["echo", "Hello World!"]) subprocess.check_output("exit 1", shell=True) subprocess.Popen(...)
check_output
执行命令,如果状态码是 0 ,则返回执行结果,否则抛异常
subprocess.check_output(["echo", "Hello World!"]) subprocess.check_output("exit 1", shell=True)
subprocess.Popen(...)
用于执行复杂的系统命令
参数:
- args:shell命令,可以是字符串或者序列类型(如:list,元组)
- bufsize:指定缓冲。0 无缓冲,1 行缓冲,其他 缓冲区大小,负值 系统缓冲
- stdin, stdout, stderr:分别表示程序的标准输入、输出、错误句柄
- preexec_fn:只在Unix平台下有效,用于指定一个可执行对象(callable object),它将在子进程运行之前被调用
- close_sfs:在windows平台下,如果close_fds被设置为True,则新创建的子进程将不会继承父进程的输入、输出、错误管道。
所以不能将close_fds设置为True同时重定向子进程的标准输入、输出与错误(stdin, stdout, stderr)。
- shell:同上
- cwd:用于设置子进程的当前目录
- env:用于指定子进程的环境变量。如果env = None,子进程的环境变量将从父进程中继承。
- universal_newlines:不同系统的换行符不同,True -> 同意使用 \n
- startupinfo与createionflags只在windows下有效
将被传递给底层的CreateProcess()函数,用于设置子进程的一些属性,如:主窗口的外观,进程的优先级等等
import subprocess ret1 = subprocess.Popen(["mkdir","t1"]) ret2 = subprocess.Popen("mkdir t2", shell=True)
终端输入的命令分为两种:
- 输入即可得到输出,如:ifconfig
- 输入进行某环境,依赖再输入,如:python
import subprocess obj = subprocess.Popen("mkdir t3", shell=True, cwd=‘/home/dev‘,)
import subprocess obj = subprocess.Popen(["python"], stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE) obj.stdin.write(‘print 1 \n ‘) obj.stdin.write(‘print 2 \n ‘) obj.stdin.write(‘print 3 \n ‘) obj.stdin.write(‘print 4 \n ‘) obj.stdin.close() cmd_out = obj.stdout.read() obj.stdout.close() cmd_error = obj.stderr.read() obj.stderr.close() print cmd_out print cmd_error
import subprocess obj = subprocess.Popen(["python"], stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE) obj.stdin.write(‘print 1 \n ‘) obj.stdin.write(‘print 2 \n ‘) obj.stdin.write(‘print 3 \n ‘) obj.stdin.write(‘print 4 \n ‘) out_error_list = obj.communicate() print out_error_list
import subprocess obj = subprocess.Popen(["python"], stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE) out_error_list = obj.communicate(‘print "hello"‘) print out_error_list
六、shutil
高级的 文件、文件夹、压缩包 处理模块
shutil.copyfileobj(fsrc, fdst[, length])
将文件内容拷贝到另一个文件中,可以部分内容
def copyfileobj(fsrc, fdst, length=16*1024): """copy data from file-like object fsrc to file-like object fdst""" while 1: buf = fsrc.read(length) if not buf: break fdst.write(buf)
shutil.copyfile(src, dst)
拷贝文件
def copyfile(src, dst): """Copy data from src to dst""" if _samefile(src, dst): raise Error("`%s` and `%s` are the same file" % (src, dst)) for fn in [src, dst]: try: st = os.stat(fn) except OSError: # File most likely does not exist pass else: # XXX What about other special files? (sockets, devices...) if stat.S_ISFIFO(st.st_mode): raise SpecialFileError("`%s` is a named pipe" % fn) with open(src, ‘rb‘) as fsrc: with open(dst, ‘wb‘) as fdst: copyfileobj(fsrc, fdst)
shutil.copymode(src, dst)
仅拷贝权限。内容、组、用户均不变
def copymode(src, dst): """Copy mode bits from src to dst""" if hasattr(os, ‘chmod‘): st = os.stat(src) mode = stat.S_IMODE(st.st_mode) os.chmod(dst, mode)
shutil.copystat(src, dst)
拷贝状态的信息,包括:mode bits, atime, mtime, flags
def copystat(src, dst): """Copy all stat info (mode bits, atime, mtime, flags) from src to dst""" st = os.stat(src) mode = stat.S_IMODE(st.st_mode) if hasattr(os, ‘utime‘): os.utime(dst, (st.st_atime, st.st_mtime)) if hasattr(os, ‘chmod‘): os.chmod(dst, mode) if hasattr(os, ‘chflags‘) and hasattr(st, ‘st_flags‘): try: os.chflags(dst, st.st_flags) except OSError, why: for err in ‘EOPNOTSUPP‘, ‘ENOTSUP‘: if hasattr(errno, err) and why.errno == getattr(errno, err): break else: raise
shutil.copy(src, dst)
拷贝文件和权限
def copy(src, dst): """Copy data and mode bits ("cp src dst"). The destination may be a directory. """ if os.path.isdir(dst): dst = os.path.join(dst, os.path.basename(src)) copyfile(src, dst) copymode(src, dst)
shutil.copy2(src, dst)
拷贝文件和状态信息
def copy2(src, dst): """Copy data and all stat info ("cp -p src dst"). The destination may be a directory. """ if os.path.isdir(dst): dst = os.path.join(dst, os.path.basename(src)) copyfile(src, dst) copystat(src, dst)
shutil.ignore_patterns(*patterns)
shutil.copytree(src, dst, symlinks=False, ignore=None)
递归的去拷贝文件
例如:copytree(source, destination, ignore=ignore_patterns(‘*.pyc‘, ‘tmp*‘))
def ignore_patterns(*patterns): """Function that can be used as copytree() ignore parameter. Patterns is a sequence of glob-style patterns that are used to exclude files""" def _ignore_patterns(path, names): ignored_names = [] for pattern in patterns: ignored_names.extend(fnmatch.filter(names, pattern)) return set(ignored_names) return _ignore_patterns def copytree(src, dst, symlinks=False, ignore=None): """Recursively copy a directory tree using copy2(). The destination directory must not already exist. If exception(s) occur, an Error is raised with a list of reasons. If the optional symlinks flag is true, symbolic links in the source tree result in symbolic links in the destination tree; if it is false, the contents of the files pointed to by symbolic links are copied. The optional ignore argument is a callable. If given, it is called with the `src` parameter, which is the directory being visited by copytree(), and `names` which is the list of `src` contents, as returned by os.listdir(): callable(src, names) -> ignored_names Since copytree() is called recursively, the callable will be called once for each directory that is copied.

shutil.rmtree(path[, ignore_errors[, onerror]])
递归的去删除文件
def rmtree(path, ignore_errors=False, onerror=None): """Recursively delete a directory tree.

shutil.move(src, dst)
递归的去移动文件
def move(src, dst): """Recursively move a file or directory to another location. This is similar to the Unix "mv" command.

shutil.make_archive(base_name, format,...)
创建压缩包并返回文件路径,例如:zip、tar
- base_name: 压缩包的文件名,也可以是压缩包的路径。只是文件名时,则保存至当前目录,否则保存至指定路径,
如:www =>保存至当前路径
如:/Users/ryan/www =>保存至/Users/ryan/
- format:压缩包种类,“zip”, “tar”, “bztar”,“gztar”
- root_dir:要压缩的文件夹路径(默认当前目录)
- owner:用户,默认当前用户
- group:组,默认当前组
- logger:用于记录日志,通常是logging.Logger对象
#将 /Users/ryan/Downloads/test 下的文件打包放置当前程序目录

shutil 对压缩包的处理是调用 ZipFile 和 TarFile 两个模块来进行的,详细:
import zipfile
# 压缩
z = zipfile.ZipFile(‘laxi.zip‘, ‘w‘) z.write(‘a.log‘) z.write(‘data.data‘) z.close()
# 解压
z = zipfile.ZipFile(‘laxi.zip‘, ‘r‘) z.extractall() z.close()
zipfile 压缩解压
import tarfile
# 压缩
tar = tarfile.open(‘your.tar‘,‘w‘) tar.add(‘/Users/ryan/PycharmProjects/bbs2.zip‘, arcname=‘bbs2.zip‘) tar.add(‘/Users/ryan/PycharmProjects/cmdb.zip‘, arcname=‘cmdb.zip‘) tar.close()
# 解压
tar = tarfile.open(‘your.tar‘,‘r‘) tar.extractall() # 可设置解压地址 tar.close()
