HomeBackend DevelopmentPython Tutorial在Python中用split()方法分割字符串的使用介绍

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)).

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 );

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']

In Python 3, two lists can be connected through a variety of methods: 1) Use operator, which is suitable for small lists, but is inefficient for large lists; 2) Use extend method, which is suitable for large lists, with high memory efficiency, but will modify the original list; 3) Use * operator, which is suitable for merging multiple lists, without modifying the original list; 4) Use itertools.chain, which is suitable for large data sets, with high memory efficiency.

Using the join() method is the most efficient way to connect strings from lists in Python. 1) Use the join() method to be efficient and easy to read. 2) The cycle uses operators inefficiently for large lists. 3) The combination of list comprehension and join() is suitable for scenarios that require conversion. 4) The reduce() method is suitable for other types of reductions, but is inefficient for string concatenation. The complete sentence ends.

Python is an interpreted language, but it also includes the compilation process. 1) Python code is first compiled into bytecode. 2) Bytecode is interpreted and executed by Python virtual machine. 3) This hybrid mechanism makes Python both flexible and efficient, but not as fast as a fully compiled language.
