Alright, this function's supposed purpose is to simply modify the object "matrix" accordingly with the dictionary comprehension. However, I don't want it to return anything. I just need the modifications to stick. Is that possible??

Don't create a new dictionary, but rather update the original one.kindall– kindall2021-12-26 19:35:40 +00:00Commented Dec 26, 2021 at 19:35

I could resolve it by doing this:
def matrix_null(matrix: dict, null: float):
to_pop = []
for key, value in matrix.items():
if value == null:
to_pop.append(key)
for key in to_pop:
matrix.pop(key)
matrix['null'] = null
# TEST:
matrix = {'abc': 123, '1': 1.0, '2': 1.0}
matrix_null(matrix, 1.0)
print(matrix)
>>> {'abc': 123, 'null': 1.0}
