Solution in Python (3.8.2) (judge verdict: Runtime Error)

alpha = input()
upperCase = ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q','R', 'S', 'T', 'U', 'V', 'W', 'X',Y','Z']
lowerCase = ['a','b', 'c', 'd', 'e','f', 'g', 'h', 'j', 'k', 'l', 'm', 'n', 'o','p', 'q', 'r', 's','t', 'u', 'v', 'w', 'x', 'y', 'z']
if alpha in upperCase:
             print("Upper Case")
if alpha in lowerCase:
             print("Lower Case")
