we have to call it on the string that’ll be used for joining. In this case, we’re using a string with a space in it. The method receives a list of strings and returns one string with each of the strings joined by the initial string. Let’s check its functionality with...
In Python, you can enclose strings in either single quotes,in quotation marks, or in triple quotes. 让我们看一下字符串上的几个常见序列操作。 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...
