The challenge
Complete the function that accepts a string parameter, and reverses each word in the string. All spaces in the string should be retained.
Examples
"This is an example!" ==> "sihT si na !elpmaxe"
"double spaces" ==> "elbuod secaps"
The solution in Python code
Option 1:
def reverse_words(text):
out = []
for word in text.split(" "):
out.append(word[::-1])
return " ".join(out)
Option 2:
def reverse_words(str):
return ' '.join(s[::-1] for s in str.split(' '))
Option 3:
def reverse_words(str):
return " ".join(map(lambda word: word[::-1], str.split(' ')))
Test cases to validate our solution

test.assert_equals(reverse_words('a b c d'), 'a b c d')
test.assert_equals(reverse_words('double spaced words'), 'elbuod decaps sdrow')
