For loop

Question

in question
letters = ['a','b']
for l in letters:
print(l)
what does 'l' indicate?
is l is constant or variable?

Answer 1

It's a variable. As the loop iterates through the array, it gets each element's value assigned to it one after another.

First iteration: l = 'a', so when you print l, it prints 'a'.
Second iteration: l = 'b', so it prints 'b'.

If you added more elements it would continue the same way with the rest of them.

Also, it doesn't have to be l, you can use any letter.

Answer 2

letters = ['a', 'b', 'c']
for l in letters :
print(l)

Right answer

Answer 3

similar to for i in range(0,10) loops from 0 to 9 for l in letters loops from 0 to len(letters)

Answer 4

letters = ['a', 'b', 'c']
for l in letters :
print(l)
