python .split

Python中的split()函数用于拆分字符串。它通过指定分隔符对字符串进行切片，并返回分割后的字符串列表。如果不指定分隔符，则默认以空格、换行、制表符为分隔符。如果指定了分隔次数，则只分隔指定次数的子字符串。

下面是几个示例：
1. 使用空格作为分隔符：`a = "I love China"，a.split()`，输出结果为 `['I', 'love', 'China']`
2. 使用逗号和空格作为分隔符：`b = "I love China, and you, you"，b.split(", ")`，输出结果为 `['I love China', 'and you', 'you']`
3. 使用井号（#）作为分隔符：`c = "I#love#China#andyou#you"，c.split("#")`，输出结果为 `['I', 'love', 'China', 'andyou', 'you']`
4. 指定分隔次数为1：`d = "I#love#China#andyou#you"，d.split("#", 1)`，输出结果为 `['I', 'love#China#andyou#you']`
5. 指定分隔次数为15：`e = "with great power comes great responsibility. I love China and you you"，e.split(" ", 15)`，输出结果为 `['with', 'great', 'power', 'comes', 'great', 'responsibility.', 'I', 'love', 'China', 'and', 'you', 'you']`

总之，split()函数可以根据指定的分隔符将字符串拆分成多个子字符串，并以列表的形式返回。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
