Python 3 Basics

1. 科学计数法：

>>> format(pow(1.3,50)*10000,‘.2e‘)

‘4.98e+09‘

2. Python文件操作

主要功能，1）扫描目录，找到APK文件；2）解析debug/release;3)使用debug/release+time生成文件名；4）复制文件到远程目录给测试。

import sys,os,shutil,zipfile,time,string,re #导入依赖库

def getTime():
    return time.strftime("%m_%d_%H_%M",time.localtime(time.time()))

    for fileName in os.listdir(MyPath):
        FilePath = os.path.abspath(os.path.join(MyPath, fileName))
        #print(‘遍历文件 ：‘ + FilePath )

#       输出找到的.txt格式的文件
        if ".apk" in fileName:
            print(‘找到apk文件 ：‘ + FilePath )
            if found==1:
                print(‘找到多个APK文件，退出‘)
                sys.exit(1)
            found =1
            foundPath = FilePath

    if found==1:
        return foundPath
    else:
