How do I check if a string has certain letters in them to delete them?

For example: The string contains the word "Traffic lights" but I want to delete every "a" and "i" letters in it and then print the string. How do I write that kind of code?

Strings have a "replace" method that would work well here. And it can be chained:

print("Traffic lights".replace("a", "").replace("i", ""))  # shows "Trffc lghts"

For more details, see the official documentation for str.replace().

Note that while it's possible, I would not recommend a long "replace" chain as a solution to the "Disemvowel" challenge. You might consider using a loop to keep the code more compact and easy to read.
