上面的代码是做什么的？我得到的输出如下
The Zen of Python, by Tim Peters
Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Readability counts.
Special cases aren't special enough to break the rules.
Although …我在正则表达式中使用字符类来拆分字符串.我假设字符类中的字符顺序无关紧要.
以下是我用来分割字符串的两种模式"123.3+23+23.3".
[+/*-]
[+*-/]
对于第一个模式,我得到的输出为:
123.3
23
23.3
对于第二种模式,我得到的输出为:
123
3
23
23
3
我不知道,为什么我得到不同的输出.请帮帮我.
