在列表中的元素中搜索子字符串，然后删除该元素 [英] Searching for substring in element in a list an deleting the element

问题描述

我有一个列表，我正在尝试删除其中包含'pie'的元素.这就是我所做的:

I have a list and I am trying to delete the elements that have 'pie' in them. This is what I've done:

['applepie','orangepie', 'turkeycake']
for i in range(len(list)):
    if "pie" in list[i]:
         del list[i]

我一直使列表索引超出范围，但是当我将del更改为print语句时，它可以很好地打印出元素.

I keep getting list index out of range, but when I change the del to a print statement it prints out the elements fine.

推荐答案

与其从正在迭代的列表中删除项目，不如尝试使用Python不错的

Instead of removing an item from the list you're iterating over, try creating a new list with Python's nice list comprehension syntax:

foods = ['applepie','orangepie', 'turkeycake']
pieless_foods =  [f for f in foods if 'pie' not in f]
