Common words
def checkio(first, second): a = set(first.split(",")) b = set(second.split(",")) return ",".join(sorted(a.intersection(b)) #These "asserts" using only for self-checking and not necessary for auto-testing if __name__ == '__main__': assert checkio("hello,world", "hello,earth") == "hello", "Hello" assert checkio("one,two,three", "four,five,six") == "", "Too different" assert checkio("one,two,three", "four,five,one,two,six,three") == "one,three,two", "1 2 3"
I get an error after checking, in PyCharm i get a syntax error like
if __name__ == '__main__': ^ SyntaxError: invalid syntax"
Can you help, please?
p.s. should i delete post after getting answer?
