# Python Program to display characters
# from A to Z or a to z using iteration
# ***************************************

# take input of the number
print("Enter 1 to display A to Z")
print("Enter 2 to display a to z")
s = int(input("Your choice >> "))

# display result
if s == 1:
    # display uppercase letters
    for i in range(ord("A"), ord("Z") + 1):
        print(chr(i), end=" ")
elif s == 2:
    # display lowercase letters
    for i in range(ord("a"), ord("z") + 1):
        print(chr(i), end=" ")
else:
    print("Wrong choice!")

Output

Case 1:

Enter 1 to display A to Z

Enter 2 to display a to z

Your choice >> 1

    # display result
    if s == 1:
        # display uppercase letters
        # by calling recursive function
        print_uppercase(ord("A"), ord("Z"))

    elif s == 2:
        # display lowercase letters
        # by calling recursive function
        print_lowercase(ord("a"), ord("z"))
    else:
