Master Python’s Number Guessing Game: Step-by-Step Code & Tips

1. Introduction

A follower asked how to implement a "guess the number" game in Python, where the program randomly selects a number and the user keeps guessing until the correct value is found.

2. Solution Process

Two community members provided complete solutions.

The logic uses a while loop, the random module, and input() to read user guesses.

import random
n=random.randint(1,100)
while True:
    a=int(input('请输入数字：'))
    if a>n:
        print('猜大了')
    elif a<n:
        print('猜小了')
    else:
        print('恭喜你猜对了')
        break

This straightforward approach works well for basic gameplay.

This version adds range feedback, updating the lower and upper bounds after each guess to make the game more interactive.

import random
key=random.randint(1,100)
btm=1
top=100
count=1
while True:
    try:
        user=int(input("请输入数字："))
    except:
        continue
    if user>key:
        print('猜大了')
        print(f'数字区间为{btm}-{user}')
        top=user
    elif user<key:
        print('猜小了')
        print(f'数字区间为{user}-{top}')
        btm=user
    else:
        print(f'恭喜你共使用{count}次机会，猜对正确数字{key}')
        if count>7:
            print('请继续努力！您还需要多练习猜数。')
        elif count==1:
            print('啥也甭说了，快去买彩票！')
        else:
            print('你真是个机灵的小可爱！')
        break
    count+=1

The author later discovered a bug where the displayed range could be incorrect; the updated code fixes this by properly adjusting the bounds before printing the hint.

import random

key = random.randint(1, 100)
btm = 1
top = 100
count = 1
while True:
    try:
        user = int(input("请输入数字："))
    except:
        continue
    if user > key:
        if top >= user:
            top = user
        print(f'错误！正确数字比{user}小，答案就在区间{btm}-{top}之中')
    elif user < key:
        if btm <= user:
            btm = user
        print(f'错误！正确数字比{user}大，答案在区间{btm}-{top}之中')
    else:
        print(f'恭喜你共使用{count}次机会，猜对正确数字{key}')
        if count > 7:
            print('请继续努力！您还需要多练习猜数。')
        elif count == 1:
            print('啥也甭说了，快去买彩票！')
        else:
            print('你真是个机灵的小可爱！')
        break
    count += 1
