What is wrong with the second function?
def count(n):
return [i for i in range (n,-1,-1)]
gives me the accurate result of [5, 4, 3, 2, 1] but
def count(n):
for i in range (n,-1,-1):
return i
always returns n.
As people have said in the comments, return stops the function and returns the value. Use a generator if you want to do something like this, but not exit the function. Also, it is recommended that you use 4 spaces for indentation by PEP 8, the official Python style guide.
def count(n):
for i in range(n, -1, -1):
yield i
print(list(count(5)))
