在使用Python的过程中,我最喜欢的就是Python的各种第三方库,能够完成很多操作。 下面就给大家介绍22个通过Python构建的项目,以此来学习Python编程。 大家也可根据项目的目的及提示,自己构建解决方法,提高编程水平。
① 骰子模拟器

② 石头剪刀布游戏
目标:创建一个命令行游戏,游戏者可以在石头、剪刀和布之间进行选择,与计算机PK。如果游戏者赢了,得分就会添加,直到结束游戏时,最终的分数会展示给游戏者。
提示:接收游戏者的选择,并且与计算机的选择进行比较。计算机的选择是从选择列表中随机选取的。如果游戏者获胜,则增加1分。
import random
choices = ["Rock", "Paper", "Scissors"]
computer = random.choice(choices)
player = False
cpu_score = 0
player_score = 0
while True:
player = input("Rock, Paper or Scissors?").capitalize()
# 判断游戏者和电脑的选择
if player == computer:
print("Tie!")
elif player == "Rock":
if computer == "Paper":
print("You lose!", computer, "covers", player)
cpu_score+=1
else:
print("You win!", player, "smashes", computer)
player_score+=1
elif player == "Paper":
if computer == "Scissors":
print("You lose!", computer, "cut", player)
cpu_score+=1
else:
print("You win!", player, "covers", computer)
player_score+=1
elif player == "Scissors":
if computer == "Rock":
print("You lose...", computer, "smashes", player)
cpu_score+=1
else: print("You win!", player, "cut", computer)
player_score+=1
elif player=='E':
print("Final Scores:")
print(f"CPU:{cpu_score}")
print(f"Plaer:{player_score}")
break
else:
print("That's not a valid play. Check your spelling!")
computer = random.choice(choices)
③ 随机密码生成器
目标:创建一个程序,可指定密码长度,生成一串随机密码。 提示:创建一个数字+大写字母+小写字母+特殊字符的字符串。根据设定的密码长度随机生成一串密码。

## sending request to server
smtp.ehlo() ## server object
smtp.starttls() ## used to send data between server and client
smtp.login("email_id","Password") ## login id and password of gmail
smtp.send_message(email) ## Sending email
print("email send") ## Printing success message

⑩ 文字冒险游戏
目的:编写一个有趣的Python脚本,通过为路径选择不同的选项让用户进行有趣的冒险。
⑪ Hangman
目的:创建一个简单的命令行hangman游戏。
提示:创建一个密码词的列表并随机选择一个单词。现在将每个单词用下划线“_”表示,给用户提供猜单词的机会,如果用户猜对了单词,则将“_”用单词替换。

import random
name = input("What is your name? ")
print ("Hello, " + name, "Time to play hangman!")
time.sleep(1)
print ("Start guessing...\n")
time.sleep(0.5)

alarm_seconds=alarm_time[6:8]
alarm_period = alarm_time[9:11].upper()
print("Setting up alarm..")
while True:
now = datetime.now()
current_hour = now.strftime("%I")
current_minute = now.strftime("%M")
current_seconds = now.strftime("%S")
current_period = now.strftime("%p")
if(alarm_period==current_period):
if(alarm_hour==current_hour):
