1. 猜字游戏
功能:通过字母猜测隐藏的水果单词
import random def guess_word_game(): words = ["apple", "banana", "cherry"] target = random.choice(words) guessed = [] attempts = 6 print("欢迎来到猜字游戏!") while attempts > 0: guess = input("猜一个字母: ").lower() if guess in guessed: print("已猜过该字母") continue guessed.append(guess) if guess in target: display = " ".join([c if c in guessed else "_" for c in target]) print(display) if "_" not in display: print("胜利!") break else: attempts -= 1 if attempts == 0: print(f"失败!答案是{target}") if __name__ == "__main__": guess_word_game()2. 加密解密工具
功能:实现凯撒密码加密与解密
def encrypt(text, shift): encrypted = "" for char in text: if char.isalpha(): base = ord('a') if char.islower() else ord('A') encrypted += chr((ord(char)-base + shift)%26 + base) else: encrypted += char return encrypted def decrypt(text, shift): return encrypt(text, -shift) # 示例 original = "Hello" encrypted = encrypt(original, 3) # 输出 Khoor decrypted = decrypt(encrypted, 3) # 还原 Hello3. 天气查询应用
功能:通过爬虫获取实时天气
import requests from bs4 import BeautifulSoup def get_weather(city): url = f" .google /search?q={city}+weather" headers = {'User-Agent': 'Mozilla/5.0'} res = requests.get(url, headers=headers) soup = BeautifulSoup(res.text, 'html.parser') location = soup.find("div", {"id": "wob_loc"}).text temp = soup.find("span", {"id": "wob_tm"}).text print(f"{location}: {temp}°C") get_weather("北京") # 示例输出:北京市天气: 25°C4. 人脸检测工具
功能:识别并裁剪图像中的人脸
import cv2 def detect_faces(image_path): face_cascade = cv2.CascadeClassifier('haarcascade_frontalface_default.xml') img = cv2.imread(image_path) gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY) faces = face_cascade.detectMultiScale(gray, 1.3, 5) for (x,y,w,h) in faces: cv2.rectangle(img, (x,y), (x+w,y+h), (255,0,0), 2) cv2.imwrite(f"face_{x}.jpg", img[y:y+h, x:x+w]) cv2.imshow('Detected Faces', img) cv2.waitKey(0) detect_faces("group_photo.jpg")5. 倒计时器
功能:实现终端倒计时
import time def countdown(seconds): while seconds: mins, secs = divmod(seconds, 60) print(f"{mins:02d}:{secs:02d}", end="\r") time.sleep(1) seconds -= 1 print("时间到!") countdown(60) # 60秒倒计时6. URL短链生成器
功能:使用API生成短链接
import pyshorteners def shorten_url(url): s = pyshorteners.Shortener() return s.tinyurl.short(url) print(shorten_url(" .example ")) # 输出类似 tinyurl /abc123项目扩展建议:
代码优化方向:
为GUI项目添加异常处理(如闹钟的非法输入检测)1使用多线程优化阻塞操作(如倒计时器的实时输入响应)3依赖管理:
安装必要库:pip install opencv-python pyttsx3 pyshorteners学习路径:
