Python初级练手项目

Python闹钟

DateTime模块以Python编程语言预先安装，因此您可以轻松地将其导入程序中。可以使用pip命令轻松安装playsound库。点安装playsound。希望您能够将其安装在系统中，现在让我们看看如何编写程序以使用Python创建闹钟警报。
在编写程序之前，您应该知道您还需要一个警报音，在警报时会响起。因此，您可以在公众号后台回复警报音获取各类警报音频 。现在，当我们准备好库和警报歌曲时，让我们看看如何编写程序以使用Python创建闹钟：

from datetime import datetime
from playsound import playsound
alarm_time = input("Enter the time of alarm to be set:HH:MM:SS\n")
alarm_hour=alarm_time[0:2]
alarm_minute=alarm_time[3:5]
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):
if(alarm_minute==current_minute):
if(alarm_seconds==current_seconds):
print("Wake Up!")
playsound('audio.mp3')
break

电子邮件切片器

要使用Python创建电子邮件切片器，我们的任务是编写一个程序，该程序可以检索电子邮件的用户名和域名。例如，查看下面的图像，其中显示了“ [email protected]”的域和用户名：

因此，我们需要使用“ @”作为分隔符将电子邮件分为两个字符串。让我们看看如何使用Python分隔电子邮件和域名：

email = input("Enter Your Email: ").strip()
username = email[:email.index("@")]
domain_name = email[email.index("@")+1:]
format_ = (f"Your user name is '{username}' and your domain is '{domain_name}'")
print(format_)

最后，我们只是格式化以打印输出。上面的代码可以根据您的需要增加更多的想法。作为初学者，您必须尝试这些类型的程序以提高您的编码技能。从长远来看，它也将帮助您构建算法并提高逻辑思考的能力。

故事生成器

我们的任务是每次用户运行程序时生成一个随机故事。我将首先将故事的各个部分存储在不同的列表中，然后可以使用Random模块来选择存储在不同列表中的故事的随机部分：

import random
when = ['几年前', '昨天', '昨晚', '很久以前','20天前']
who = ['一只兔子', '一只大象', '一只老鼠', '一只乌龟','一只猫咪']
name = ['Ali', 'Miriam','daniel', 'Hoouk', 'Starwalker']
residence = ['杭州','上海', '北京', '广东', '深圳']
went = ['电影院', '大学','超市', '学校', '公园']
happened = ['交了很多朋友','吃了个汉堡', '找到一个藏宝图', '解决了一个问题', '写了本书']
print(random.choice(when) + ', ' + random.choice(who) + ' that lived in ' + random.choice(residence) + ', went to the ' + random.choice(went) + ' and ' + random.choice(happened))

密码生成器

要编写Python程序来创建密码，请声明数字字符串+大写字母+小写字母+特殊字符。随机抽取用户指定长度的字符串：

import random
passlen = int(input("输入密码的长度"))
s="a[email protected]#$%^&*()?"
p = "".join(random.sample(s,passlen ))
print(p)

石头剪刀布的游戏

使用Python创建石头、剪刀、布的游戏，我们需要接受用户的选择，然后将其与使用Python随机模块从选择列表中获得的计算机选择进行比较，如果用户获胜，那么分数将增加1：

import random
choices = ["Rock", "Scissors", "Paper"]
computer = random.choice(choices)
player = False
cpu_score = 0
player_score = 0
while True:
player = input("Rock，Scissors，Paper？").capitalize()
## 游戏状况
if player == computer:
print("平局!")
elif player == "Rock":
if computer == "Paper":
print("你输了", computer, "covers", player)
cpu_score+=1
else:
print("你赢了", player, "smashes", computer)
player_score+=1
elif player == "Paper":
if computer == "Scissors":
print(你输了!", computer, "cut", player)
cpu_score+=1
else:
print("你赢了!", player, "covers", computer)
player_score+=1
elif player == "Scissors":
if computer == "Rock":
print("You lose...", computer, "smashes", player)
cpu_score+=1
else:
print("你赢了!", player, "cut", computer)
player_score+=1
elif player=='End':
print("Final Scores:")
print(f"CPU:{cpu_score}")
print(f"Plaer:{player_score}")
break

骰子滚动模拟器

#导入random模块用于随机数生成
import random
#骰子的范围
min_val = 1
max_val = 6
#to loop the rolling through user input
roll_again = "yes"
#循环
while roll_again == "yes" or roll_again == "y":
print("Rolling The Dices...")
print("The Values are :")
#打印并生成1-6的第一个随机数
print(random.randint(min_val, max_val))
#打印并生成1-6的第二个随机数
print(random.randint(min_val, max_val))
#告诉用户再次掷骰子，除yes或者y的任何输入都会终止程序
roll_again = input("Roll the Dices Again?") 

QR码生成器

在本节中，我将带您学习如何使用Python生成QR码的教程。要使用Python生成QR码，您只需安装一个Python库即可完成此任务

pip install pyqrcode

现在让我们看看如何使用Python编程语言创建QR代码：

import pyqrcode
from pyqrcode import QRCode
# 代表QR码的字符串
s = "https://www.youtube.com/channel/UCeO9hPCfRzqb2yTuAn713Mg"
# 生成QR码
url = pyqrcode.create(s)
# 创建并保存命名为"myqr.png"的文件
url.svg("myyoutube.svg", scale = 8) 

使用Python打印彩色文本

使用Colorama模块，我们可以使用Python打印彩色文本。我们可以使用它并调用其内置变量，这些变量是所需ANSI代码的别名。这使我们的代码更具可读性，并且在脚本开始时调用colorama.init（）后可以更好地与Windows命令提示符配合使用。

import colorama
from colorama import Fore, Back, Style
colorama.init(autoreset=True)
print(Fore.BLUE+Back.YELLOW+"Hi My name is Aman Kharwal "+ Fore.YELLOW+ Back.BLUE+"I am your Machine Learning Instructor")
print(Back.CYAN+"Hi My name is Aman Kharwal")
print(Fore.RED + Back.GREEN+ "Hi My name is Aman Kharwal")

带Python的BMI计算器

Height=float(input("输入你的身高（cm）"))
Weight=float(input("输入你的体重（kg） "))
Height = Height/100
BMI=Weight/(Height*Height)
print("your Body Mass Index is: ",BMI)
if(BMI>0):
if(BMI<=16):
print("you are severely underweight")
elif(BMI<=18.5):
print("you are underweight")
elif(BMI<=25):
print("you are Healthy")
elif(BMI<=30):
print("you are overweight")
else: print("you are severely overweight")
else:("enter valid details")

华氏温度转摄氏温度转换器

def convert(s):
f = float(s)
c = (f - 32) * 5/9
return c
print(convert(78))

接收多个用户输入

假设系统提示您编写一个Python程序，该程序在控制台窗口中与用户交互。您可能正在接受输入以发送到数据库，或者正在读取要在计算中使用的数字。

无论目的是什么，您都应该编写一个循环，以从键盘上键入的用户读取一个或多个用户输入，并为每个输出打印结果。换句话说，您必须编写一个经典的打印循环程序。

while True:
reply = input("输入文本: ")
if reply == 'stop': break
print(reply)

罗马数字转换为小数

因此，我们需要按照上述逻辑编写一个程序，以使用Python将罗马数字转换为小数。因此，让我们看一下将罗马数字转换为小数的过程：

从左到右浏览罗马数字字符串，一次检查两个相邻的字符。如果需要的话，还可以指定循环的方向，但是没有关系，只要相应地实现了比较即可。

1. 如果左侧的值大于右侧的值，则从最终值中减去该位置的计数。否则，只需添加它。

一旦处

1. 如果左侧的值大于右侧的值，则从最终值中减去该位置的计数。否则，只需添加它。
2. 一旦处理完成，最终值就是罗马数字的十进制值。

tallies = {
'I': 1,
'V': 5,
'X': 10,
'L': 50,
'C': 100,
'D': 500,
'M': 1000,
# specify more numerals if you wish
}
def RomanNumeralToDecimal(romanNumeral):
sum = 0
for i in range(len(romanNumeral) - 1):
left = romanNumeral[i]
right = romanNumeral[i + 1]
if tallies[left] < tallies[right]:
sum -= tallies[left]
else:
sum += tallies[left]
sum += tallies[romanNumeral[-1]]
return sum
