Python Web Development Techdegree Student 7,538 PointsCode Challenge: Map
For the code challenge: "Create a function named "reverse" which takes a single iterable as an argument, and returns a reversed version of that item."
I have entered this code into workspaces and the terminal--it works perfectly fine in both places. However, the code challenge keeps giving me a "Bummer! reverse didn't accept an argument."
For the life of me, I cannot figure out what's wrong here.
backwards = [
'tac',
'esuoheerT',
'htenneK',
[5, 4, 3, 2, 1],
]
def reverse(i):
i = iter(i)
idx = len(i)
i2 = ""
while idx:
idx -= 1
i2 += i[idx]
return i2

Python Web Development Techdegree Student 7,538 PointsFigured it out, for anyone interested or also struggling--The code above WILL reverse strings and integers...however, something the test code is throwing at it is not compatible.
The correct solution was to use a slice, which steps backward through the iterable and returns the reverse:
def reverse(iterable):
return iterable[::-1]
