Q:

python find if each element of a string list contains any of another string list

suppose I have two string list: 
a=['ab','ac','ad']
b=['abcd','baa','bacd','bbaa']

and I want to know if each element of list b has any of strings in a as its substring. The correct result should be: [True,False,True,False]. How do I code this? 

A:

You can use built-in function any within a list comprehension:
>>> [any(i in j for i in a) for j in b]
[True, False, True, False]
