Python Exercises

1. Exercise 1

Design a program to help students practice addition within 10
Details:
- randomly generated addition topic;
- students view the subject and enter the answers;
- determine students answer correctly?
- When you exit, the total number of statistics students answer, the correct amount and the correct rate (Reserved two decimal places);

import random

count = 0
right = 0
while True:

     num1 = random.randint(0, 10)
     num2 = random.randint(0, 10)
     print('题目：%d+%d= ' % (num1, num2))
     answer = num1 + num2
     answer1 = input('请输入你的答案(输入exit退出)')
     if answer1 == str(answer):
         right += 1
         count += 1
         print('你答对了')
     elif answer1 == 'exit':
         a = right / count
         print("你共答了%d道题,正确%d道题，正确率为%.2f%% " %(count, right, a*100))
         break
     else:
         print('你答错了')
         count += 1

Output:

2. English II

Primary arithmetic capability test system:
design a program to help implement arithmetic pupils within one hundred practice,
it has the following functions:
to provide 10 to add, subtract, multiply or topic other four basic arithmetic operations;
practitioners of the display title input their answers;
the program automatically determines if the input answer is correct and display the corresponding information.

import random

op = ['+', '-', '*', '/']
i=0
for i in range(1,11):
    a = random.choice(op)
    num1=random.randint(0,100)
    num2=random.randint(0,100)
    print('%d%s%d='%(num1,a,num2))
    if a == '+':
        ans=num1+num2
    if a == '-':
        ans=num1-num2
    if a == '*':
        ans=num1*num2
    if a == '/':
        ans=num1/num2
    ans1=int(input('输入你的答案：'))
    if ans1==ans:
        print('答案正确')
    else:
        print('答案错误，正确答案为%d' %(ans))
print('练习结束')
