How can I iterate through a string in Python?

You can use a for loop to iterate through each character in a string. For example:

my_string = "Hello"
for char in my_string:
    print(char)

What if I want to get the index of each character?

You can use the enumerate() function, which provides both the index and the character:

for index, char in enumerate(my_string):
    print(index, char)

Can I iterate in reverse order?

Yes, you can use slicing to reverse the string:

for char in my_string[::-1]:
    print(char)

Are there any built-in functions for string iteration?

Yes, functions like map() can be used to apply a function to each character in a string. For example:

result = list(map(str.upper, my_string))
