删除Python列表中包含数字的所有项目 [英] Remove all items in Python list containing a number

问题描述

从大量字符串中删除所有包含数字的项的最佳方法是什么?

What is an optimal way of removing all items containing a number from a large list of strings?

输入:['This'，'That'，'Those4423'，'42'，'13b''是'，'2']

Input: ['This', 'That', 'Those4423', '42', '13b' 'Yes', '2']

输出:['This'，'That'，'Yes']

Output: ['This', 'That', 'Yes']

推荐答案

>>> foo = ['This', 'That', 'Those4423', '42', '13b', 'Yes', '2']
>>> foo1 = [x for x in foo if not any(x1.isdigit() for x1 in x)]
>>> foo
['This', 'That', 'Those4423', '42', '13b', 'Yes', '2']
>>> foo1
['This', 'That', 'Yes']
>>>

但是，您可以使用.isalpha()检查字符串是否仅包含字母字符.

However you can use .isalpha() to check if the string contains alphabetic characters only.

.isaplha()
 [x for x in foo if x.isalpha()]
