Valueholder solution in Clear category for Replace Last by Dm_Ch
def replace_last(line: list) -> list:
# Without additional valueholder:
# if len(line) > 1:
# for x in range(len(line)-1, 0, -1):
# line[x], line[x-1] = line[x-1], line[x]
# return line
# With additional valueholder:
return [line.pop()] + line if len(line) > 1 else line
if __name__ == '__main__':
print("Example:")
print(replace_last([2, 3, 4, 1]))
# These "asserts" are used for self-checking and not for an auto-testing
assert replace_last([2, 3, 4, 1]) == [1, 2, 3, 4]
assert replace_last([1, 2, 3, 4]) == [4, 1, 2, 3]
assert replace_last([1]) == [1]
assert replace_last([]) == []
