How to isolate dictionary data in Python

Question

I have created database of different payments in different departments:

paymentType={"Cash":0,"Amex":0,"All Other Cards":0}
departments={"Lounge":0,"MBar":0,"Resto":0,"TBar":0,"TFloor":0,"Events":0}
for dep in departments.keys():
    data=paymentType
    departments[dep]=data

however, when I assign value to one of “paymentType” in specific department

departments["Lounge"]["Cash"]=8

it changes “Cash” value in all “departments”

I would like to keep ability to assign value by string, thats why I didnt use class.

Because you've assigned the **same dictionary** to every key in the `departments` dictionary. — juanpa.arrivillaga, Oct 30 '19 at 19:24
Can I assign new entity of same dictionary ? To speed up process, so I dont have to repeat same code. — Matus Hmelar, Oct 30 '19 at 19:27

You need to use

data=paymentType.copy()

otherwise you assign the same dictionary to all fields.
