A long parameter list can indicate that a new structure should be created to wrap the numerous parameters or that the function is doing too many
things.
Noncompliant Code Example
With a maximum number of 4 parameters:
def do_something(param1, param2, param3, param4, param5):
...
Compliant Solution
def do_something(param1, param2, param3, param4):
...
Exceptions
The first argument of non-static methods, i.e. self
or cls
, is not counted as it is mandatory and it is passed
automatically.
