python中的删除:remove()、pop()、del 这三种方法都是list的删除方法,其中remove是针对可变列表的元素进行搜索删除,而pop和del是针对可变列表的下标进行搜索删除。具体区别如下: remove(item)方法是直接对可变序中的元素进行检索删除,返回的是删除后的列表,不返回删除值(返回None),若有重复元素,则按顺序删除第一...
Python:remove在list遍历时使用会发生什么 技术标签: python remove先来看看这个简单的程序: a=[1,2,3,4,5] for i in a: if i != 2 a.remove(i) print(a) 按照刚开始学习python 时候的想法,remove的作用是将list中的元素删除掉,那么这一次的输出必然是 [2] 但是在实际使用时,发现发生了错误,list的...
