The Prompt
You need to write a Python program that systematically generates all possible three-letter usernames using lowercase English letters.
The program should:
– Utilize the letters ‘a’ through ‘z’ from the English alphabet.
– Generate every combination of three letters (with repetitions allowed).
– Print each username on a separate line.
# Steps
1. Define the string `alphabet` containing all lowercase letters.
2. Use the `itertools.product` function with `repeat=3` to create all possible 3-letter combinations.
3. Iterate over the generated combinations.
4. Join each tuple of letters into a string.
5. Print each username string.
# Output Format
– Print all generated usernames, one per line.
– Ensure there is no additional text in the output.
# Example
If `alphabet = ‘ab’` and `repeat = 2`, the output should be:
“`
aa
ab
ba
bb
“`
