python清除html文件中内容的方法：1、使用join方法，代码为【pat = re.compile('>(.*?)<')''.join(pat.findall(test))】；2、使用compile方法。

本教程操作环境：windows7系统、python3.9版，DELL G3电脑，该方法适用于所有品牌电脑。

python清除html文件中内容的方法：

方法1：

In [97]: str_ = ''
    ...: flag = 1
    ...: for ele in test:
    ...:     if ele == "<":
    ...:         flag = 0
    ...:     elif ele == '>':
    ...:         flag = 1
    ...:         continue
    ...:     if flag == 1:
    ...:         str_ += ele
    ...:         
In [98]: str_
Out[98]: 'just for testjust for testtest'
In [99]: str_ = ''
    ...: flag = 1
    ...: for ele in test:
    ...:     if ele == "<":
    ...:         flag = 0
    ...:     elif ele == '>':
    ...:         flag = 1
    ...:         ele = ' '
    ...:     if flag == 1:
    ...:         str_ += ele
    ...:         
In [100]: str_
Out[100]: ' just for test   just for test  test '

方法2：

import re
In [156]: pat = re.compile('(?<=\>).*?(?=\<)')
In [157]: pat.findall(test)
Out[157]: ['just for test', '', '', 'just for test', '', 'test']
In [158]: ''.join(pat.findall(test))
Out[158]: 'just for testjust for testtest'

方法3：

pat = re.compile('>(.*?)<')
''.join(pat.findall(test))

方法4：

In [167]: pat = re.compile('<[^>]+>', re.S)
In [168]: pat.sub('', test)
Out[168]: 'just for testjust for testtest'
