I have done here I wrote a two line script from python and I submitted it but
they said it is a wrong answer but I can't understand why is that my code is follow

print(' '.join(l))

Can anyone tell me what is wrong with my code
(it fails on test cases 1 / 3 / 4 / 5 with Python 3, so )

If you don't specifiy the separator to str.split(), "any whitespace string is a separator and empty strings are removed from the result." Note that here "whitespace" includes tabs, newlines etc.

The problem is not clearly specified (there's no definition of what "word" means) and we don't know what they use for test cases, but I assume they have a couple string with newlines or such. Anyway: explicitely specifying " " as the separator makes the tests pass:

# Python 2
s = raw_input()
print " ".join(x.capitalize() for x in s.strip().split(" "))

# Python 3
s = input()
print(" ".join(x.capitalize() for x in s.strip().split(" ")))
