unicode string equivalent of contain

Question

I have an error when trying to use contain in python.

s = u\"some utf8 words\"
k = u\"one utf8 word\"

if s.contains(k):
    print \"contains\" 

Answer 1

There is no difference between str and unicode.

print u"ábc" in u"some ábc"
print "abc" in "some abc"

is basically the same.
