What are first-class functions in Python?

First-class functions are functions that can be treated like any other variable. They can be passed as arguments, returned from other functions, and assigned to variables.

Can you give me an example of a first-class function?

Sure! Here's a simple example:

def greet(name):
    return f'Hello, {name}!'

def call_function(func, name):
    return func(name)

print(call_function(greet, 'Alice'))  # Output: Hello, Alice!

What are the benefits of using first-class functions?

They promote higher-order functions, enable functional programming techniques, and enhance code reusability and modularity.

Are there any limitations to first-class functions?

One limitation is that they can lead to less readable code if overused, making it harder to understand the flow of the program.
