经典入门编程题

1.猜数字

经典的猜数字游戏，几乎所有人学编程时都会做。

功能描述： 随机选择一个三位以内的数字作为答案。用户输入一个数字，程序会提示大了或是小了，直到用户猜中。

#!/usr/bin/env python3import randomresult = random.randint(1,999)while True:num = int(input("please input number between 0-999:"))if num == result:print ("you are right")breakelif num > result:print("high")else :print("low")

2. FizzBuzz

另一道经典编程题。

功能描述：遍历并打印0到100，如果数字能被3整除，显示Fizz；如果数字能被5整除，显示Buzz；如果能同时被3和5整除，就显示FizzBuzz。结果应该类似：0,1,2，Fizz，4，Buzz，6……14，FizzBuzz，16……

for num in range(101):if num % 3 == 0 and num % 5 == 0:print("FizzBuzz", end=", ")elif num % 3 == 0:print("Fizz", end=", ")elif num % 5 == 0:print("Buzz", end=", ")else:print(num, end=", ")
#! /usr/bin/env python3num = 0
while num < 100:num += 1if num % 3 == 0 && num % 5 == 0:print("FizzBuzz".",")elif num % 3 == 0:print("Fizz".",")elif num % 5 == 0:print("Buzz".",")else:print(num.",")
while num =100:print("Buzz")break

3.猜数字的AI

和猜数字一样，不过这次是设计一个能猜数字的AI

功能描述：用户输入一个单位以内的数字，AI要用最少的次数猜中，并且显示出猜的次数和数字。

import randomdef guess_number():low = 1high = 100  # 可根据需要调整上下限target = int(input("请输入一个1到100之间的数字："))count = 0while True:guess = random.randint(low, high)count += 1print("AI猜的数字是：", guess)if guess == target:print("AI猜中了！猜的次数是：", count)breakelif guess < target:print("AI猜的数字太小了！")low = guess + 1else:print("AI猜的数字太大了！")high = guess - 1guess_number()

#!/usr/bin/env python3import randomanswer = random.randint(0,999)guess = random.randint(0,999)
count = 0while True:if guess < answer:print("AI guess number is ",guess)print("but it is low")guess = random.randint(guess,999)count += 1elif guess > answer :print("AI guess number is ",guess)print("but it is high")guess = random.randint(0,guess)count += 1else :print ("AI guess number is ",guess)print("it is right ")count += 1breakprint("it guess ",count,"times")
