Function Overloading in Python

In python same name function may be defined within the class or outside but last function overwrite the previous functions .In python same name function with same arguments may also be declared in but not possible in java c++ etc.

def display(age):
print(“age=”,age)

def display(name,age):
  print("name=",name," age=",age)

# display(26) it will give error as last function takes two argument and we pass here only 1 arugment.

display(‘john’,25) # second function executes which takes only 1 arg

Output:
name=john age=25

Similaryly overloading may be in the class as following

class Area:
 def areaCal(self,a,b):
  area=a*b
  print("area=",area)

 def areaCal(self,a):
  area=a*a
  print("area=",area)

a1=Area ()

# a1.areaCal(10,20) it will give error as last function takes only one argument and we pass here 2 arugments.

a1.areaCal(20) # second function executes which takes only 1 arguments

Output:
Area=400
