In [2]: word = "福建"

In [3]: [i for i in data if word in i]
Out[3]: ['福建省']

 

方法2：

In [4]: data=["北京市", "福建省", "河南省", "杭州市"]

In [5]: word = "福建"

In [6]: list(filter(lambda x: word in x, data))
Out[6]: ['福建省']

　　

方法3：

In [7]: import re

In [8]: data=["北京市", "福建省", "河南省", "杭州市"]

In [9]: word = "福建"

In [10]: [x for x in data if re.search(word, x)]
