How do you check each letter of a word?

Short answer. Use a for loop: for ch in word gives one letter each round.

How do you get the index while looping?

Loop over range(len(word)) to get each index.

Remember

for ch in word: one by one
range(len(word)) gives index

How do you check each letter of a word? Traversing means visiting each character in order. The variable ch, short for character, takes one letter each round. For ch in word gives each letter. Range of length gives each index.
