检查子字符串是否在字符串列表中? [英] Check if substring is in a list of strings?

问题描述

我之前已经找到了这个问题的一些答案，但是它们对于当前的Python版本似乎已经过时了(或者至少它们对我不起作用).

I have found some answers to this question before, but they seem to be obsolete for the current Python versions (or at least they don't work for me).

我要检查字符串列表中是否包含子字符串.我只需要布尔结果.

I want to check if a substring is contained in a list of strings. I only need the boolean result.

我找到了这个解决方案:

I found this solution:

word_to_check = 'or'
wordlist = ['yellow','orange','red']

result = any(word_to_check in word for word in worldlist)

从此代码中，我希望得到一个True值.如果单词是"der"，则输出应为False.

From this code I would expect to get a True value. If the word was "der", then the output should be False.

但是，结果是生成器函数，我找不到获取True值的方法.

However, the result is a generator function, and I can't find a way to get the True value.

有什么主意吗?

推荐答案

您可以从__builtin__导入any，以防被其他any代替:

You can import any from __builtin__ in case it was replaced by some other any:

>>> from  __builtin__ import any as b_any
>>> lst = ['yellow', 'orange', 'red']
>>> word = "or"
>>> b_any(word in x for x in lst)
True

请注意，在Python 3中，__builtin__已重命名为builtins.

Note that in Python 3 __builtin__ has been renamed to builtins.
