Hi, this is my first post on this mailing list-
I wanted to ask about this type of execution in python,
expected output-
reverse_words("This is an example!") # returns "sihT si na !elpmaxe"
below is my execution, followed by another persons execution, which i dont
completely understand.
def reverse_words(strng):
strng = strng[::-1].split(' ')
strng.reverse()
return ' '.join(strng)
def reverse_words(s)
return ' '.join(s[::-1] for s in str.split(' '))
how can a for loop be called within another method like that- and possibly
what situations does this benefit
i don't even know how to google this sort of thing
any words are appreciated-
It's tricky, isn't it? Once I give you the magic phrase, you'll find
examples and explanations all over the place:
list comprehension
(strictly, the example you're showing is a "generator comprehension" but
you'll probably get more hits for the slightly older "list comprehension").
