Let’s look at a couple of common sequence operations on strings. 让我先定义一个字符串。 Let me first define a string. 让我们来看看“Python” Let’s just go with "Python." 同样,如果我想知道我的字符串有多长,我可以使用len函数。 Again, if I wanted to find out how long is my string,...
str.join(iterable) Return a string which is the concatenation of the strings in the iterable iterable. A TypeError will be raised if there are any non-string values in iterable, including bytes objects. The separator between elements is the string providing this method....

In this tutorial, you'll learn how to remove or replace a string or substring. You'll go from the basic string method .replace() all the way up to a multi-layer regex pattern using the sub() function from Python's re module.
Concatenate any number of strings. The string whose method is called is inserted in between each given string. The result is returned as a new string. Example: '.'.join(['ab', 'pq', 'rs']) -> 'ab.pq.rs' 连接任意数量的字符串。
