小学四则运算

代码

import random

def szys():
sym = ['+', '-', '×', '÷']

f = random.randint(0, 3)

n1 = random.randint(1, 20)

n2 = random.randint(1, 20)

result = 0

if f == 0:  

    result = n1 + n2

elif f == 1:  

    n1, n2 = max(n1, n2), min(n1, n2)

    result = n1 - n2

elif f == 2:  

    result = n1 * n2

elif f == 3:  

    n1, n2 = max(n1, n2), min(n1, n2)

    while n1 % n2 != 0:
        n1 = random.randint(1, 10)

        n2 = random.randint(1, 10)

        n1, n2 = max(n1, n2), min(n1, n2)

    result = int(n1 / n2)

print(n1, sym[f], n2, '= ', end='')

return result

def test():
sym = ['+', '-', '×', '÷']

print('输入所需要的题目数量')

n = int(input())

result = []

m = 0

while m <= (n - 1):
    print(m + 1, end='、')

    result.append(szys())

    print(' ')

    m = m + 1

m = 0

print('对应的答案:')

while m <= (n - 1):
    print(m + 1, '、', result[m])

    m = m + 1

print('选择想要的模式')

print('1、进行四则运算')

print('2、制作题库')

n = int(input())

if n == 1:

while True:

    result = szys()

    j = input()

    s = int(j)

    if s == result:

        print('right')

    else:

        print('error.,the answer is', result)

if n == 2:
test()
