请大家帮我看看 Python基础改错问题谢谢（新手求助）

Question

 from random import choice
def goal(i,score_you):
   print('========round %d u kick=========' % i+1)
   print('choose one side to shoot:')
   print(list(direction))
   you=input()
   print('you kicked'+ you)
   com=choice(direction)
   print('computer saved '+ com)
   if you != com:
       print('goal!')
       score_you += 1
   else:
       print('oops~')
def save(i,score_com):
   print('========round %d u save======== '% i+1)
   print('choose one side to save:')
   print(list(direction))
   you = input()
   print('you saved'+ you)
   com= choice(direction)
   print('computer kicked '+ com)
   if you != com:
       print('goal')
       score_com +=1
   else:
       print('oops~')


score_you = 0
score_com = 0
direction=('left','center','right')

for i in range(5):
    if (i+2)/2 == 0:
        goal(i,score_you)
        print('''round %d
            you:%d computer:%d'''% (i+1,score_you,score_com))
    else:
        save(i,score_com)
        print('''round %d
            you:%d computer:%d''' % (i + 1, score_you, score_com))

下面这是错误信息：
C:\Users\heavymetalmaniac\AppData\Local\Programs\Python\Python36-32\python.exe C:/Users/heavymetalmaniac/PycharmProjects/list_goal/goal.py
Traceback (most recent call last):

File "C:/Users/heavymetalmaniac/PycharmProjects/list_goal/goal.py", line 16, in save
print('========round %d u save======== '% i+1)
TypeError: must be str, not int
应该怎么改啊

Answer 1

print('========round %d u save======== '% i+1)
TypeError: must be str, not int
他都错误告诉你了吗，需要字符串，不能是int。
你把i+1用括号括起来就行了吗
print('========round %d u save======== '%(i+1))
