What are some exercises to practice Python functions?

Here are a few exercises you can try:

1. Write a function that returns the factorial of a number.
2. Create a function that checks if a string is a palindrome.
3. Write a function that finds the maximum number in a list.

Can you give me an example of the factorial function?

Sure! Here's a simple implementation:

def factorial(n):
    if n == 0:
        return 1
    else:
        return n * factorial(n - 1)

What about the palindrome check?

Here's a function to check for palindromes:

def is_palindrome(s):
    return s == s[::-1]

Thanks! How can I test these functions?

You can test them by calling the functions with different inputs. For example:

print(factorial(5))  # Output: 120
print(is_palindrome('racecar'))  # Output: True
