二年级上数学练习题生成

作为一个家长不容易啊

 1  1 #coding:utf-8
 2  2 import random
 3  3 #小学二年级上数学练习（100以内加减乘）
 4  4 #生成的题数
 5  5 count = 50
 6  6 #每行题数
 7  7 lineNum = 5
 8  8 while count > 0:
 9  9     #获取符号1为加，2为减，3为乘
10 10     operator = random.randint(1,3)
11 11     #获取操作数和操作结果
12 12     str = ""
13 13     num1 = num2 = result = 0
14 14     if operator == 3:   #乘法口诀
15 15         num1 = random.randint(1,9)
16 16         num2 = random.randint(1,9)
17 17         result = num1*num2
18 18         str = "X"
19 19     elif operator == 2: #减法
20 20         num1 = random.randint(2,100)
21 21         num2 = random.randint(1,num1)
22 22         result = num1 - num2
23 23         str = "-"
24 24     else:               #加法
25 25         num1 = random.randint(1,100)
26 26         num2 = random.randint(0,100-num1)
27 27         result = num1 + num2
28 28         str = "+"
29 29     print("%d%s%d=\t\t" %(num1,str,num2),end = "")
30 30     count -= 1
31 31     if count%5 == 0:
32 32         print()
