b: To allow the user to call a function without specifying a value for an argument Explanation

Explanation

c: To prevent a function from having more than one argument Explanation

Explanation

d: None of the above Explanation

Explanation

Which of the following is an example of a required argument in Python?

Explanation

b: def func(a, b): Explanation

Explanation

c: def func(a=1, b=2): Explanation

Explanation

d: None of the above Explanation

Explanation

What is the purpose of using the **kwargs syntax in Python?

a: To allow a function to accept an arbitrary number of keyword arguments Explanation

Explanation

b: To require a function to have at least one keyword argument Explanation

Explanation

c: To prevent a function from accepting any keyword arguments Explanation

Explanation

Explanation

Which of the following is an example of a function with variable-length arguments in Python?

a: def func(a, b=1, *args): Explanation

Explanation

b: def func(a, b=2): Explanation

Explanation

c: def func(a=1, b=2): Explanation

Explanation

d: All of the above Explanation

Explanation

What distinguishes a keyword argument from a required argument in Python?

a: When invoking a function, required parameters must be supplied in the correct order, whereas keyword arguments can be specified in any order. Explanation

Explanation

b: Unlike keyword arguments, which must be called using their name, required arguments can be called using their name. Explanation

Explanation

c: Keyword arguments have a default value, whereas required arguments must be supplied with a value when calling a function. Explanation

Explanation

d: While keyword arguments may have a default value, required arguments do not. Explanation

Explanation

Which of the following is an example of a function with both default and keyword arguments in Python?

a: def func(a, b, c=1, d): Explanation

Explanation

b: def func(a=1, b, c=2, d=3): Explanation

Explanation

c: def func(a, b, *args, **kwargs): Explanation

Explanation

d: All of the above Explanation

Explanation

What happens if a required argument is not provided when calling a Python function?

a: It will throw an Error Explanation

Explanation

b: The function will use the default value for the argument, if it has one Explanation

Explanation

c: The function will use the last provided argument for the missing argument. Explanation

Explanation

d: All of the above Explanation

Explanation

Can a function have both variable-length arguments and keyword arguments in Python?

a: Yes, but the variable-length arguments must come before the keyword arguments. Explanation

Explanation

b: No, a function can have either variable-length arguments or keyword arguments, but not both. Explanation

Explanation

c: It depends on the specific use case and function requirements. Explanation

Explanation

d: All of the above Explanation

Explanation

Which of the following is an example of a function with required arguments only in Python?

a: def func(a, b=1, **kwargs): Explanation

Explanation

b: def func(a, b, c): Explanation

Explanation

c: def func(*args): Explanation

Explanation

d: None of the Above Explanation

Explanation
