How are default parameters different from keyword parameters give examples?

Default arguments mean you can leave some parameters out. Instead of f(1, 2, 3) you can just write f(1) or f(1, 2) . Keyword arguments mean you don’t have to put them in the same order as the function definition. Instead of f(1, 2, 3) you can do f(c=3, b=2, a=1) .

Can you assign the default values to a function parameters?

It is called default function parameters . It allows formal parameters to be initialized with default values if no value or undefined is passed.

How many parameters can a Python function have?

What is the utility of 2 I default arguments in keyword arguments?

There are two advantages – one, using the function is easier since we do not need to worry about the order of the arguments. Two, we can give values to only those parameters to which we want to, provided that the other parameters have default argument values.

What is the default value of take_power in Python?

No value has been provided for the default argument integer2. Hence, the default value of 2 will be used to take the power of 3 and you will see 9 in the output. Let’s now pass two values to the take_power () function.

What is a mutable default argument in Python?

Python’s default arguments are evaluated once when the function is defined, not each time the function is called. This means that if you use a mutable default argument and mutate it, you will and have mutated that object for all future calls to the function as well.
