First solution in Clear category for Sort Except Zero by frichard44
from collections.abc import Iterable

not_zero = []
zero_idx = []
# First pass, get index of zeros and list of anything else than zero
for i in range(len(items)):
if items[i] == 0:
zero_idx.append(i)
else:
not_zero.append(items[i])
# second pass, prepare result
result = []
not_zero = sorted(not_zero)
for i in range(len(items)):
if i in zero_idx:
result.append(0)
else:
result.append(not_zero.pop(0))
return result
print("Example:")
print(list(except_zero([5, 3, 0, 0, 4, 1, 4, 0, 7])))
# These "asserts" are used for self-checking
