冒泡排序

def bubbleSort(arr): n = len(arr) for i in range(n): for j in range(0, n - i - 1): if arr[j] > arr[j + 1]: arr[j], arr[j + 1] = arr[j + 1], arr[j] arr = [8, 5, 7, 19, 4, 5, 9] bubbleSort(arr) print("排序后的数组:") for i in range(len(arr)): print("%d" % arr[i], end=" ") 排序后的数组: 4 5 5 7 8 9 19

猜数字小游戏

import random number = random.randint(0, 9) n = 0 while (True): try: use_input = int(input("请输入数字：")) n += 1 if use_input == number: print(f'预测了{n}次，你猜中了') break elif use_input > number: print("遗憾，太大了") else: print("遗憾，太小了") except ValueError: print("输入必须为整数！ ") continue 请输入数字：5 遗憾，太小了 请输入数字：8 遗憾，太小了 请输入数字：9 预测了3次，你猜中了

猜数字小游戏 函数版

import random def user_input(n): while (True): try: use_input = int(input("请输入数字：")) n += 1 if use_input == number: print(f'预测了{n}次，你猜中了') break elif use_input > number: print("遗憾，太大了") else: print("遗憾，太小了") except ValueError: print("输入必须为整数！ ") continue number = random.randint(0, 9) n = 0 user_input(n) 请输入数字：2 遗憾，太大了 请输入数字：1 遗憾，太大了 请输入数字：0 预测了3次，你猜中了

字符串敏感词过滤

Sensitive_list = ["茄子", "香蕉"] new_str = input("请输入一句话:") for i in Sensitive_list: new_str = new_str.replace(i, '*') print(new_str) 请输入一句话：茄子 香蕉 **

异常捕获练习

try: alp = "ABCDEFGHIJKLMNOPQRSTUVWXYZ" idx = eval(input("请输入一个整数")) print(alp[idx]) except NameError: print("输入错误，请输入一个整数！") else:print("没有发生异常") finally: print("程序执行完毕，不知道是否发生了异常") 请输入一个整数斤斤计较 输入错误，请输入一个整数！ 程序执行完毕，不知道是否发生了异常

年会 年会 你在哪

month_input = eval(input("请输入月份: ")) if month_input == 1: print("这个月有年会。") date_input = eval(input("请输入当天日期: ")) if date_input <= 12: print(f'距离举办年会还有{12 - date_input}天') else: print("这个月没有年会") else: print("已经开过年会了") 请输入月份: 2 已经开过年会了

生日歌

def happy(): print("Happy birthday to you!") def happyB(name): happy() happy() print("Happy birthday, dear {}!".format(name)) happy() happyB("Mike") print() happyB("Lily") Happy birthday to you! Happy birthday to you! Happy birthday, dear Mike! Happy birthday to you! Happy birthday to you! Happy birthday to you! Happy birthday, dear Lily! Happy birthday to you!
