Back to curriculumNext lesson

Summary

Use **kwargs to accept arbitrary keyword arguments and process them.

Problem statement

Implement count_kwargs(**kwargs) which accepts any number of keyword arguments and returns an integer count of those keyword arguments. The function should work when called with zero or many keyword arguments.

Task

Create a function count_kwargs(**kwargs) that returns how many keyword arguments were passed.

Examples

Count two keyword args

Input

count_kwargs(name='Alice', active=True)

Output

2

Explanation

Two keyword arguments (name and active) were provided.

Input format

Zero or more keyword arguments in the form key=value.

Output format

An integer representing the number of keyword arguments passed.

Constraints

Do not use external libraries. The order of kwargs is not important; only the count matters.

Samples

Sample input 0

count_kwargs()

Sample output 0

0

Explanation 0

No keyword arguments, so the count is 0.
