Default parameter function in python

Equals sign ( = ) indicates the default parameter. When the function is called without using the argument, the default parameter will be executed.

Syntax:

def function_name( argument = value )

        #method of body

Example-1

def message( Name, Age = 20):

    print(Name ,"age : ",Age)
    
message("Hari")

Output

Hari age :  20

Example-2

def message(Name, Age = 20):

    print(Name ,"age : ",Age)

message("Hari")

message("Krishna",25)

Output

Hari age :  20
Krishna age :  25
