从1~100之间猜测数字

import random
numMin = 1
numMax = 100
m = random.randint(numMin, numMax)
while True:
    n = eval(input('请输入你猜测的整数：'))
    if n > m:
        print("区间为{}到{}".format(numMin,n))
        numMax = m
    elif n < m:
        print("区间为{}到{}".format(n,numMax))
        numMin = n
    if n == m:
        print("恭喜你，猜对了！！")
        break
