How do I use the map function with strings in Python?

You can use the map() function to apply a function to each item in an iterable, like a list of strings. For example, if you want to convert a list of strings to uppercase, you can do this: list(map(str.upper, my_list)).

Can you show me a complete example?

Sure! Here's a complete example:

my_list = ['apple', 'banana', 'cherry']
result = list(map(str.upper, my_list))
print(result)  # Output: ['APPLE', 'BANANA', 'CHERRY']

What if I want to apply a custom function instead?

You can define your own function and pass it to map(). For instance:

def add_exclamation(s):
    return s + '!'

my_list = ['apple', 'banana', 'cherry']
result = list(map(add_exclamation, my_list))
print(result)  # Output: ['apple!', 'banana!', 'cherry!']
