python第七天

Posted 2020-08-05 北方姆Q

上周出现了意外情况延迟了好几天，这几天又在整云平台，真是累成汪汪了，还有个叫ossim的安全管理平台，一个可以让服务器红屏的系统，北方还真是第一次见到红屏，涨姿势了啊~~~蓝屏大家肯定都已经习惯了嘛，当时以为要爆炸了。

今天早上公司又在开洗脑大会，北方还怕你不成啊？来啊，互相伤害啊！，企业文化跟中二病你觉得我会选哪个

 

1.configparser模块：以后可以对该类型的配置文件进行操作了呦

 1 #!/usr/bin /env python
 2 import configparser
 3 config = configparser.ConfigParser()
 4 config.read(\'a.txt\', encoding=\'utf-8\')
 5 ret = config.sections()                     #获取所有节点名
 6 print(ret)
 7 
 8 ret = config.options(\'test1\')               #获取指定节点下的key
 9 print(ret)
10 
11 ret = config.get(\'test1\', \'k1\')               #获取指定节点下的值
12 print(ret)
13 
14 has = config.has_section(\'test1\')               #验证是否包含节点
15 print(has)
16 
17 has = config.has_section(\'tttt1\')               #验证是否包含节点
18 print(has)
19 
20 config.add_section(\'tttt1\')                     #加节点(节点不可以存在)
21 config.write(open(\'a.txt\', \'w\', encoding=\'utf-8\'))
22 
23 config.remove_section(\'tttt1\')                  #删节点（节点存在）
24 config.write(open(\'a.txt\', \'w\', encoding=\'utf-8\'))
25 
26 has = config.has_option(\'tttt1\', \'k1\')               #验证是否包含节点内的key
27 print(has)
28 
29 config.add_option(\'tttt1\', \'k1\')                     #加节点内key（节点存在）
30 config.write(open(\'a.txt\', \'w\'))
31 
32 config.remove_option(\'tttt1\', \'k1\')                  #删节点内key（节点存在）
33 config.write(open(\'a.txt\', \'w\'))

1 [test1]
2 k1 = v1
3 k2 = 123
4 
5 [test2]
6 k1 = ace
7 
8 [test3]
9 k1 = kkk

2.xml模块：xml是一种语法，类似于网页返回字符串后用json来格式化，获取数据后继续我们的操作

1 #!/usr/bin /env python
2 from xml.etree import ElementTree as ET
3 tree = ET.parse(\'a.xml\')
4 root = tree.getroot()                           #获取根节点
5 #print(root)
6 for child in root:                              #打印子节点
7     # print(child.tag, child.attrib)
8      for cchild in child:
9          print(cchild.tag, cchild.attrib,cchild.text)       #命名，标注，值

12     r_string = ET.tostring(elem, encoding=\'utf-8\')
13     rep = minidom.parseString(r_string)
14     return rep.toprettyxml(indent=\'\\t\')
15 
16 
17 root = ET.Element(\'family\')                                 #根节点命名
18 
19 son1 = ET.Element(\'son\', {\'name\': \'son1\'})                  #子节点命名

25 son1.append(grandson1)                                             #子节点添加孙节点

32 # tree.write(\'b.xml\', encoding=\'utf-8\', short_empty_elements=False)
33 
34 raw_str = prettify(root)
35 
36 with open(\'b.xml\', \'w\', encoding=\'utf-8\') as f:
37     f.write(raw_str)

1 <?xml version="1.0" ?>
2 <family>
3     <son name="son1">
4         <grandson name="grandson1"/>
5     </son>

 3.面向对象！！！！！！！！！

 1 #!/usr/bin /env python
 2 class F1:
 3 
 4     def show(self):
 5         print(\'show\')
 6 
 7     def foo(self):

 9 
10 
11 class F2(F1):

13     def __init__(self, name):
14         self.name = name

23 obj.foo()

我草，看不懂啊....其实我懂，但是我不知道怎么写.....反正很nb就是了.....

 

我就不说话，我就发图
