Python:查找字符串中的单词

Question

我想在字符串中查找单词，如下所示:

kkk="I do not like that car."

if "like" in kkk:
    print("like")
elif "dislike" in kkk:
    print("dislike")
elif "hate" in kkk:
    print("hate")
elif "cool" in kkk:
    print("cool")

但是由于我的代码很长，我想将其缩短:

if "like" in kkk or "dislike" in kkk or "hate" in kkk or "cool" in kkk:
    #print "like" 
    #unable to do it this way

然后我尝试使用另一种方式，但没有成功:

a=["like","dislike","hate","cool"]

if any(x in kkk for x in a):
    print(x)
    #NameError: name 'x' is not defined

Answer 1

试试这个:

>>> kkk="I do not like that car."
>>> a=["like","dislike","hate","cool"]
>>> print(*[x for x in a if x in kkk])
like

此列表理解与以下相同:

for x in a:
    if x in kkk:
        print(x)
