split()方法返回的字符串中的所有单词的列表，使用str作为分隔符(如果在未指定的所有空格分割)，可选择限当前分割为数量num。
语法

以下是split()方法的语法：

str.split(str="", num=string.count(str)).
Copy after login

参数

  • str -- 这是任何分隔符，默认情况下是空格。
  • num -- 这是要分割的行数。

返回值

此方法返回行列表。
例子

下面的示例演示了split()方法的使用。

#!/usr/bin/python

str = "Line1-abcdef \nLine2-abc \nLine4-abcd";
print str.split( );
print str.split(' ', 1 );
Copy after login

当我们运行上面的程序，它会产生以下结果：

['Line1-abcdef', 'Line2-abc', 'Line4-abcd']
['Line1-abcdef', '\nLine2-abc \nLine4-abcd']
Copy after login
