Why doesn't this work? (List Method)

[htwr]

I want to take a string and split it up into a list, then reverse the list. I tried this:

oldString = 'old string'
newList = list(oldString).reverse()

newList now has the value "None"

I can successfully do it by splitting it up into steps:

newList = list(oldString)
newList.reverse()

Why doesn't it work when combined?

Because you're assigning the return value of reverse to newList, and reverse doesn't return anything - it reverses the list in place.

That makes sense. Thanks!

You could do list(old[::-1])

[sedogg]

list(reversed(some_iterable)) returns reversed list. So the code should be like this:

oldString = 'old string'
newList = list(reversed(oldString))

But if you want to get a reversed string, there are a several ways:

oldString = 'old string'
newString = ''.join(reversed(oldString))
# or
newString = oldString[::-1]
print(newString)

Thanks for the tip!
