There are no rules as such. Some of the Tkinter classes for excample
take a lot of arguments.

But you can usually simplify it by using default values and named 
parameters.
Also can any of the input values be grouped together into an object?
OOP means programming with objects, and that includes passing
whole objects aropund as arguments.

But with only a generic example to guide us we can only offer limited help.
