str.split(sep=None,maxsplit=-1) 1. sep:分隔符,默认为None,表示使用空格作为分隔符。 maxsplit:最大分割次数,默认为-1,表示不限制分割次数。 下面是一个简单的示例,演示了split方法的基本用法: text="apple,banana,cherry"fruits=text.split(",")print(fruits)# ['apple', 'banana', 'cherry'] 1. 2...
如果不讲这个关键字转化为整型,结果是这样的: sorted(s, key=lambda d : d.split('-')[-1].split('.')[0]) ['Chr1-1.txt', 'Chr1-10.txt', 'Chr1-14.txt', 'Chr1-2.txt', 'Chr1-20.txt', 'Chr1-3.txt', 'Chr1-5.txt'] 这相当于把这个关键字当做字符串了,很显然,在python中,...
1、reverse()(1)reverse()是python列表独有的内置方法,在字典,元组,字符串中是不能够使用这个方法的,它用于将列表中的元素反转,颠倒。(2)作用列表后不会返回新列表,而是修改原来的列表 语法:list.reverse()参数:NA该方法并没有返回值; 例子: 2、reversed()(1)reversed()是python内置的一个 ...
