belkkaToday I've learned that in Python arguments and parameters are different things. I used to use these terms interchangeably.
In short: parameters are the names that you use in the function definition, and arguments are the values that you pass to the function when you call it.
So, turns out, arguments do not always become exact values of function parameters — namely, when you use var-positional and var-keyword parameters (?) According to the python.org's example,
def func(**kwargs):
pass
func(foo='bar')
here the argument is 'bar', but the parameter is kwargs. During the call, the parameter's value is {'foo': 'bar'}.
