What happens if an instance method is declared without self in python

Question

I was debugging some python code and I came across a bunch of instance methods declared without self. I was curious as to what happens here. Does self get assigned to the first variable declared here?

The code is something like shown below.

class myClass:
 def myFunc (var1, var2):
 return var2

Here is self assigned to var1 ?

• jonrsharpe: Why not print var1 and find out?
• Devil: @jonrsharpe : Thanks. Should have done that. Did not think of that. Printing does confirm what people have answered here.

Answer 1

Yes, self (that is, the instance) will be assigned to the first variable (assuming there is no decorator like classmethod or staticmethod).

Answer 2

Your code snippet is equivalent to

class myClass:
 def myFunc(self, var2):
 return var2

The first parameter is passed the instance; name is irrelevant.
