python-3.x - Python加法数学测验

Question

只是学习python，我试图做一个非常简单的数学测验，但运行时出现语法错误，请解释我做错了什么

from random import randint
inf = 0
while inf < 10:
    num1 = randint(0,5000)
    num2 = randint(0,5000)
    ans = num1+num2
    print(num1,"+",num2)
    plrans = input(int()"What's the answer?")
    if plrans = ans
        print("Correct!")
    else
        print("Incorrect :(")

Answer 1

这里有些错误:

获得输入后，应完成到 int的转换。

=是赋值运算符。为了检查是否相等，您应该使用==运算符

您的if语句缺少冒号(:)

您的else语句也是如此:

from random import randint
inf = 0
while inf < 10:
    num1 = randint(0,5000)
    num2 = randint(0,5000)
    ans = num1+num2
    print(num1,"+",num2)
    plrans = int(input("What's the answer?")) # issue 1
    if plrans == ans : # issues 2 and 3
        print("Correct!")
    else: # issue 4
        print("Incorrect :(")
