Global vs. Local Variables

[Larz60+]

Are you looking for something like this?

A = []

def update_dict(dname, value, clear=False):
    if clear:
        dname = []
    dname.append(value)
    print(f"Dict contents: {dname}")


update_dict(A, 44)
update_dict(A, 35)
update_dict(A, 55, clear=True)

Output:
Dict contents: [44]
Dict contents: [44, 35]
Dict contents: [55]
