Default arguments and positional arguments in Python

Question

1. Define a function called user_name_definition with two arguments: f_name and l_name similar to the above example.
2. Set the default value for f_name to be "John"
3. Set the default value for l_name to be "Doe"

Syntax:-

def user_name_definition(name1, name2):
return name1 + ' ' + name2

f_name = "John"
l_name = "Doe"
print(user_name_definition(f_name, l_name))

or

def user_name_definition(f_name, l_name):
return f_name + ' ' + l_name

f_name = "John"
l_name = "Doe"
print(user_name_definition(f_name, l_name))

Out Put: John Doe

however I'm getting bellow validation issue:-

Answer 1

Hi HBhZ_C,

Thanks for your prompt response and I got the correct syntax as below.

def user_name_definition(f_name='John', l_name='Doe'):
return f_name + ' ' + l_name

f_name = "John"
l_name = "Doe"
print(user_name_definition(f_name, l_name))

Answer 2

default value for any parameter will be in function definition not in function call so when defined params for the function set their default value:
def func(fname="Jhon",lname="Doe"){
}
