which results in the continuous repetition of the string as many times as the number indicates. Also, if we want to find out thelengthof the string, we simply have to use thelen() function as shown in the example below:
>>>fromreimportsearch >>>type(search) <class'function'> 如下图所示: 可以看到,直接使用import re导入的re它是一个module类,也就是模块。我们把它成为正则表达式模块。而当我们from re import search时,这个search是一个function类,我们称呼它为search ...
