Concise algorithm solution in Speedy category for Replace First by Igor_Sekretarev
from typing import Iterable
def replace_first(items: list) -> Iterable:
for i in range(len(items)-1):
items[i], items[i+1] = items[i+1], items[i]
return items
if __name__ == '__main__':
print("Example:")
print(list(replace_first([1, 2, 3, 4])))
# These "asserts" are used for self-checking and not for an auto-testing
assert list(replace_first([1, 2, 3, 4])) == [2, 3, 4, 1]
assert list(replace_first([1])) == [1]
assert list(replace_first([])) == []
