一、一个简单的类调用
#!/usr/bin/env python
#-*- coding:utf-8 -*-
#5188179
class Role(object):
def __init__(self,Name,Weapon,LifeValue):
self.name = Name
self.weapon = Weapon
self.LifeValue = LifeValue
def BuyWeapon(self,weapon):
print("%s buy %s " %(self.name,weapon))
self.weapon = weapon
p1 = Role("ckl","B11",99)
t1 = Role("zld","B12",100)
print(p1.weapon)
print(t1.weapon)
p1.BuyWeapon("B44")
t1.BuyWeapon("B51")
print(p1.weapon)
print(t1.weapon)
二、关于module说明
2.1.xml

2 #-*- coding:utf-8 -*-

4
5 读取xml文件，通过段落标识符
6 import xml.etree.ElementTree as ET
7
8 tree = ET.parse("test.xml")
9 root = tree.getroot()
10 print(root.tag)
11
12 for child in root:
13 print(child.tag,child.attrib)
14 for i in child:
15 print(i.tag,i.text)
16
17 for node in root.iter(‘year‘):
18 print(node.tag,node.text)
19
20
21
22 修改xml，给year字段加1
23 import xml.etree.ElementTree as ET
24 tree = ET.parse("test.xml")
25 root = tree.getroot()
26
27 for node in root.iter(‘year‘):
28 new_year = int(node.text) + 1
29 node.text = str(new_year)
30 node.set("updated","yes")
31
32 tree.write("test.xml")
33
34
35
36 删除country字段中rank值大于50的
37 import xml.etree.ElementTree as ET
38 tree = ET.parse("test.xml")
39 root = tree.getroot()
40
41 for country in root.findall(‘country‘):
42 rank = int(country.find(‘rank‘).text)
43 if rank > 50:
44 root.remove(country)
45
46 tree.write(‘test.xml‘)
47
48
49
50 创建xml
51
52 import xml.etree.ElementTree as ET
53 new_xml = ET.Element("NameList")
54 name = ET.SubElement(new_xml,"name",attrib={"enrolled":"yes"})
55 age = ET.SubElement(name,"age",attrib={"checked":"no"})
56 sex = ET.SubElement(name,"sex")
57 sex.text = ‘33‘
58 name2 = ET.SubElement(new_xml,"name",attrib={"enrolled":"no"})
59 age = ET.SubElement(name2,"age")
60 age.text = ‘19‘
61
62 et = ET.ElementTree(new_xml)
63 et.write(‘test.xml‘,encoding="utf-8",xml_declaration=True)
64 ET.dump(new_xml)
