import random

comNum = random.randint(1,3)
userSelect = int(input('가위/바위/보: 1.가위 \t2.바위 \t 3.보'))

if (comNum == 1 and userSelect == 3) or \
    (comNum == 2 and userSelect == 1) or \
    (comNum == 3 and userSelect == 2):
     print('컴퓨터 승!  ')
elif (comNum == 2 and userSelect == 2) or \
    (comNum == 1 and userSelect == 1) or \
    (comNum == 3 and userSelect == 3):
    print('비김비김!  ')
elif (comNum == 1 and userSelect == 2) or \
    (comNum == 2 and userSelect == 3)or \
    (comNum == 3 and userSelect == 1):
     print('유저 승!  ')

2. 팩토리얼

fNum = int(input('숫자를 입력하세요: '))

#전체합
addSum = 0

for i in range(1, (fNum + 1)):
    addSum += i

addSumFormat =format(addSum, ',')
print('합 결과: {}'.format(addSumFormat))

#홀수합
oddSum = 0

for i in range(1, (fNum + 1)):
    if i % 2 != 0:
        oddSum += i

oddSumFormat =format(oddSum, ',')
print('홀수합 결과: {}'.format(oddSumFormat))

#짝수합
evenSum = 0

for i in range(1, (fNum + 1)):
    if i % 2 == 0:
        evenSum += i

evenSumFormat =format(evenSum, ',')
print('짝수합 결과: {}'.format(evenSumFormat))

#팩토리얼의 경우는 시작이 1! 
facResult = 1

for i in range(1, (fNum + 1)):
    facResult *= i

facResultFormat =format(facResult, ',')
print('팩토리얼합 결과: {}'.format(facResultFormat))

3. 반복문(별)
