Elements in the list can be accessed with
[] brackets. We can slice lists like strings with [] as well:l = [77, 0, -1, 4, 2, 1, 5, -2]
print(l) # [77, 0, -1, 4, 2, 1, 5, -2]
print(l[2]) # -1
print(l[1: 3]) # [0, -1]
print(l[1: 4]) # [0, -1, 4]
print(l[1: 5]) # [0, -1, 4, 2]
print(l[2: 3]) # [-1]
print(l[:2]) # [77, 0]
print(l[2:]) # [-1, 4, 2, 1, 5, -2]Challenge
Declare a variable called
alphabet that keeps all the uppercase letters of the English language: alphabet = ['A', 'B', ..., 'Z']. The input contains a single integer n. The program should print the first n letters in the alphabet. It’s guaranteed that 1 ≤ n ≤ 26.Input | Output |
