How can I check if any of the strings in an array exists in another string?

Like:

a = ['a', 'b', 'c']
str = "a123"
if a in str:
  print "some of the strings found in str"
else:
  print "no strings found in str"

That code doesn't work, it's just to show what I want to achieve.

Answer

You can use any:

a_string = "A string is more than its parts!"
matches = ["more", "wholesome", "milk"]

if any(x in a_string for x in matches):

Similarly to check if all the strings from the list are found, use all instead of any.
