问题的解决思路:
1.生成随机数
2.生成随机算数运算符
3.输入题目数量
4.用户输入答案
5.输出正确答案
代码:
def result(s,n1,n2): if s == ‘+‘: print(‘{} + {} = {}‘.format(n1,n2,n1 + n2)) elif s == ‘-‘: print(‘{} - {} = {}‘.format(n1,n2,n1 - n2)) elif s == ‘*‘: print(‘{} * {} = {}‘.format(n1,n2,n1 * n2)) elif s == ‘/‘: if n2 == 0: print(‘***除数不能为零***‘) else: print(‘{} / {} = {}‘.format(n1,n2,n1 / n2)) else: print(‘输入有误,请重新输入!‘)
def zsResult(): qes = int(input()) for a in range(qes): rsign = random.choice([‘+‘,‘-‘,‘*‘,‘/‘]) rnum1 = random.randint(0,100) rnum2 = random.randint(0,100) if rnum1 < rnum2: rnum1 = max(rnum1, rnum2) rnum2 = min(rnum1, rnum2) result(rsign,rnum1,rnum2) else: result(rsign,rnum1,rnum2)
def zfsResult(): qes = int(input()) for b in range(qes): rsign = random.choice([‘+‘,‘-‘,‘*‘,‘/‘]) snum1 = random.randint(0,100) mnum1 = random.randint(1,100) zfs1 = Fraction(snum1, mnum1) snum2 = random.randint(1,100) mnum2 = random.randint(1,100) zfs2 = Fraction(snum2, mnum2) if zfs1 < zfs2: zfs1 = max(zfs1, zfs2) zfs2 = min(zfs1, zfs2) result(rsign,zfs1,zfs2) else:
result(rsign,zfs1,zfs2
