Example : A function program in Python is used to show the Default Argument/Parameter.
def msg(name="World"):
return f"Hello, {name}!"
print(msg()) # Output: Hello, World! Default Parameter.
print(msg("India")) # Output: Hello, India!
NB: Here, the default value is 'World'. When the parameter value is not supplied to the function then default value works.
