What are some examples of using kwargs in Python?

In Python, kwargs allow you to pass a variable number of keyword arguments to a function. For example:

def greet(**kwargs):
    for key, value in kwargs.items():
        print(f'{key}: {value}')

# Calling the function

greet(name='Alice', age=30, city='New York')

Can you explain how kwargs work in that example?

Sure! In the greet function, **kwargs collects all keyword arguments into a dictionary. You can then iterate over this dictionary to access each key-value pair.

Are there any limitations to using kwargs?

Yes, while kwargs are flexible, they can make your function calls less clear. It's also important to ensure that the keys you use are unique to avoid overwriting values.

Can you show me another example of kwargs in a different context?

Absolutely! Here's another example with a function that creates a user profile:

def create_profile(**kwargs):
    profile = kwargs
    return profile

# Creating a profile

user_profile = create_profile(name='Bob', age=25, occupation='Engineer')
print(user_profile)
