How do I find a string in a list that matches a string or substring in another list

How can I find a string in List1 that is a substring of any of the strings in List2? Both lists can be of different lengths.

Say I have:

List1=['hello', 'hi', 'ok', 'apple']

List2=['okay', 'never', 'goodbye']

I need it to return 'ok', seeing as it was the only string in list1 that matched list2.

I wrote this piece of code to implement the 

List1=['hello', 'hi', 'ok', 'apple']
List2=['ok', 'never', 'goodbye']
i=[]
for j in List1:
    for k in List2:
        if j==k:
            i.append(j)

print i

You can use list comprehension as:

[x for x in List1 for y in List2 if x in y]

If you want to know if a string from list1 is in list2 you can do

for s in List1:
    if s in List2:
        print("found s in List2")
