You can loop over lists, but did you know you can also loop over strings? A loop over a string goes character by character, processing one letter at a time.

How it reads

for char in word: assigns each letter of "neon" to char in sequence

char.upper() converts the current letter to uppercase

Cloud tip: Looping through characters or items is called iteration. It is one of the most common tasks in programming.
