python - 列表查找中部分字符串匹配的一行

Question

是否有更简单的方法来执行以下操作？

filename = 'vudu_hail_20140101.xml'
acceptable_stems = ['vudu', 'google']

process_file = False
for acceptable_stem in acceptable_stems:
    if acceptable_stem in filename:
        process_file = True

基本上，我正在寻找一个 bool 决定因素，以确定其中一个词干是否在文件名中。这将如何使用单线完成？

Answer 1

如何使用 any关键词:

any([acceptable_stem in filename for acceptable_stem in acceptable_stems])

例子:

>> filename = 'vudu_hail_20140101.xml'
>> acceptable_stems = ['vudu', 'google']
>> any([acceptable_stem in filename for acceptable_stem in acceptable_stems])
True

>> filename = 'vudu_hail_20140101.xml'
>> acceptable_stems = ['vuduf', 'google']
>> any([acceptable_stem in filename for acceptable_stem in acceptable_stems])
False
