python - How to reverse the order of the words in a string

E.g:

 input:  I live in New York
 output: York New in live I

P.S: I have used s[::-1], this just reverses the string, like kroY weN ni evil I, but this is not the desired output. I also tried :

def rev(x) :
    x = x[::-1]
    for i in range(len(x)) :
        if x[i] == " " :
            x = x[::-1]
            continue
        print x

But this also stands incorrect. Kindly help me in writing the code.

You can use split to get the separate words, reverse to reverse the list, and finally join to join them again to make the final string:

s = "This is New York"
# split first
a = s.split()
# reverse list
a.reverse()
# now join them
result = " ".join(a)
# print it
print(result)

results in:

'York New is This'
