Python检查字符串是否包含Python中的所有单词

Question

I want to check if all words are found in another string without any loops or iterations:

a = ['god', 'this', 'a']

sentence = "this is a god damn sentence in python"

all(a in sentence)

should return TRUE .

Answer 1

You could use a set depending on your exact needs as follows:

a = ['god', 'this', 'a']
sentence = "this is a god damn sentence in python"

print set(a) <= set(sentence.split())

This would print True , where <= is issubset .

Answer 2

It should be:

all(x in sentence for x in a)

Or:

>>> chk = list(filter(lambda x: x not in sentence, a)) #Python3, for Python2 no need to convert to list
[] #Will return empty if all words from a are in sentence
>>> if not chk:
        print('All words are in sentence')
