How to Assign Default Values to Function Parameters

In Python, you can set default values for function parameters, which are known as Default Parameters.

Default parameters use pre-defined values when no argument is passed during a function call.

To define default parameters, assign a default value to the parameter using the = operator in the function definition.

Copy
# Set the default value of the name parameter to "CodeFriend"
def greet(name="CodeFriend"):
    return f"Hello, {name}!"

# "Hello, CodeFriend!"
print(greet())

In the code above, the greet function has a name parameter, with the default value set to "CodeFriend" using name="CodeFriend".

With default parameters, you do not need to provide a value for those parameters during the function call.

Copy
def greet(name="CodeFriend"):
    return f"Hello, {name}!"

# "Hello, CodeFriend!"
print(greet())

# "Hello, Python!"
print(greet("Python"))
