本文主要是介绍用python生成小学生一年级算术模板，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
孩子学习口算压力山大，现在的要求太高了需要5分钟内答满150道题，完成这个目标需要多多的练习。
加法要求和不能大于21，考虑到20以上的进位问题，孩子目前还是不熟练没有添加进去。减法差不能是负数，被减数是个位数的。除法先取乘法的商作为被除数，这样就可以被整除了。还加入了左右括号的填空，灵活转换被加数和被减数的算法。由于输出的加减乘除符号字符会因为字体不同而有差异，在pycharm的控制台输出是整齐排列的，而复制到word就会各种不对齐，对比使用Courier New字体排列的最完美了。所以复制到word要修改一下字体，达到强迫症的对齐要求。

口算大概是需要一步步的练习，先从没有进位的加减，接着是只涉及十位的加减，然后是个位数的有进退位的加减，最后是混合的加减。一个个阶梯拾级而上，练习进步。出现的被加减数为0的可能性比较大，去除为0的可能。随机数random.randint(a, b)，a不可以大于b,否则报错ValueError: empty range for randrange() (1,1, 0)，因此要加入分支条件，当a=1时，剔除b=0的情形。
int(a/10) 取出被加数的十位数， a%10 求余取出被加数的个位数
def generate_num():a = random.randint(0, 99)oper = random.choice(operList)if oper == "-":# t1是个位的减法，不涉及退位,被减数是两位数同时个位是0，则进行十位的减法if a == 0:t1 = 0elif a % 10 == 0:t1 = random.randint(1, int(a / 10)) * 10else:t1 = random.randint(1, a % 10)# t2是十位的减法，个位为零if a < 10:t2 = random.randint(1, 10)else:t2 = random.randint(1, int(a / 10)) * 10# t3是个位的减法，都是有退位的，被减数个位相同，再随机一次t3 = random.randint(a % 10,9)if t3 == a % 10:t3 = random.randint(a % 10 +1, 10)b = random.choice([ t1,t2,t3]) # b = random.randint(1, 10)if a < b:a, b = b, aans = eval('%d%s%d' % (a, oper, b))oper = "-"elif oper == "+":# p1是个位的加法，不涉及进位p1 =random.randint(1, 10 - (a % 10))# p2是十位的加法if a>=90:p2 = random.randint(1, 10 - (a % 10))else:p2 =random.randint(1, 9 - int(a / 10)) * 10# p3是个位的加法，都是有进位if a >= 90:p3 = random.randint(1, 100 -a)elif a %10 ==0: #把求余为0的可能去除掉，方便下面randint下标不越界p3 =random.randint(1, 9 - int(a / 10)) * 10else:p3 = random.randint( 10-a % 10, 9)b = random.choice( [p1,p2,p3]) ans = eval(str(a) + oper + str(b))if str(a) + oper + str(b) in unique:a, b, oper, ans = generate_num()unique.append(str(a) + str(oper) + str(b))return a, b, oper, ans
输出结果如下：可以将 b = random.choice([ t1,t2,t3]) 只剩下一个，从t1到t3,逐个打印。
