Gnome Sort not sorting in python? [duplicate]

-1

This question already has an answer here:

Python Script returns unintended “None” after execution of a function

1 answer

When I try to run my code it returns with none.

def gnomeSort(lis):
 i = 0
 n = len(lis)
 while i < n:
 if i and lis[i] < lis[i-1]:
 lis[i], lis[i-1] = lis[i-1], lis[i]
 i -= 1
 else:
 i += 1
 return


lis = [1,3,5,20,19,30,2,6,19,23,31,90,44,62,69,21,78,89,64]
print(gnomeSort(lis))

When I run this it returns with "None", even though I provided a list to be sorted.

your return statement is not returning anything, hence None, try return lis

You need to put something after your return statement, as currently it is not returning anything

This implementation sorts in-place, meaning you just call it on lis and then print lis.

Your wrote your function much like the built-in sort functions: it sorts the list in place and returns None. Print the sorted list, not the return value.

print(lis)
