[Python] Why does my Python for loop skip the last element in a list?

I’m working on a simple Python program where I want to print all the items in a list. Here’s my code:

numbers = [1, 2, 3, 4]
for i in range(len(numbers)-1):
print(numbers)


Problem: The code is only printing:

1
2
3


But it is skipping the last number 4.

What I tried:

I tried printing len(numbers) and it shows 4, which is expected.
