How to do function overloading in python?

Question

def add(x,y):
return x+y

def add(x,y,z):
return x+y+z

print(add(5,7))

Answer 1

Subhadeep Mandal, creating a variable, function or class in python overwrites the previous variable with the same name, but if you want to use multiple args, see this example:

Answer 2

Python does not support overloading.

You can define two functions with the same name, but the last one overrides the other.

In your case:

def add(x,y):
return x+y

#here you can call add(5,7)

def add(x,y,z):
return x+y+z

#here you can only call add(1,2,3)

Answer 3

The only way it can be done is in subclasses.

class A:
def __init__(self):
self.val = 5

def print_val(self):
print(self.val)

class B(A):
def __init__(self):
super().__init__()

def print_val(self):
print(self.val * 2)

a = A()
b = B()

a.print_val()
b.print_val()

# output
5
10
