Python 乘法测验语法错误

Question

在编写一个总体上为用户创建包含 10 个乘法问题的测验的程序时，我遇到了一个语法错误，但未能成功修复。当我尝试运行代码时，出现语法错误，指向 "if userAns == numAns:" 之后的冒号这是我的代码：

import random
numOne = 0
numTwo = 0
numRight = 0
numProblems = 0
numAns = 0
userAns = 0

while numProblems < 10:
    numProblems+=1
    numOne = random.randint(0,100)
    numTwo = random.randint(0,100)
    numAnswer = numOne*numTwo
    userAnswer = int(input("What is:",numOne,"*",numTwo,"?")
    if userAns == numAns:
        numRight += 1
if numRight >0<3:
    print("That was pretty bad.. ")
elif numRight >3 and numRight<=6:
    print("Hey not bad..")
elif numRight >6 and numRight <=9:
    print("You're pretty good....")
elif numRight == 10:
    print("OK OK...You're smarter than me...")
else:
    print("ERROR")

感谢您提供的任何帮助

Answer 1

此行需要一个右括号。

userAnswer = int(input("What is:",numOne,"*",numTwo,"?"))

而且你最好这样写提示信息：

...
while numProblems < 10:
    numProblems+=1
    numOne = random.randint(0,100)
    numTwo = random.randint(0,100)
    numAnswer = numOne*numTwo
    hint = "What is:" + str(numOne) + "*" + str(numTwo) + "?"
    userAnswer = int(input(hint))

    if userAns == numAns:
        numRight += 1
...

Answer 2

网上有几个问题userAnswer = ...：

末尾缺少括号
input 需要一个参数

为了解决这些问题，试试这个：

userAnswer = int(input("What is: {} * {}? ".format(numOne, numTwo)))
