大家好，我是陈程~

在应用 Python 的过程中，我最喜爱的就是 Python 的各种第三方库，可能实现很多操作。

上面就给大家介绍 8 个通过 Python 构建的我的项目，以此来学习 Python 编程。

大家也可依据我的项目的目标及提醒，本人构建解决办法，进步编程程度。

目标：编写一个 Python 脚本，主动从提供的链接读取文章。

import pyttsx3

import requests

from bs4 import BeautifulSoup

url = str(input("Paste article url\n"))

def content(url):

res = requests.get(url)

soup = BeautifulSoup(res.text,'html.parser')

articles = []

for i in range(len(soup.select('.p'))):

article = soup.select('.p')[i].getText().strip()

articles.append(article)

contents = " ".join(articles)

return contents

engine = pyttsx3.init('sapi5')

voices = engine.getProperty('voices')

engine.setProperty('voice', voices[0].id)\

def speak(audio):

engine.say(audio)

engine.runAndWait()\

contents = content(url)

## print(contents) ## In case you want to see the content#engine.save_to_file

#engine.runAndWait() ## In case if you want to save the article as a audio file

目标：编写一个 Python 脚本，能够应用这个脚本发送电子邮件。

提醒：email 库可用于发送电子邮件。

import smtplib 

from email.message import EmailMessage

email = EmailMessage() ## Creating a object for EmailMessage

email['from'] = 'xyz name'   ## Person who is sending

email['to'] = 'xyz id'       ## Whom we are sending

email['subject'] = 'xyz subject'  ## Subject of email

email.set_content("Xyz content of email") ## content of email

with smtlib.SMTP(host='smtp.gmail.com',port=587)as smtp:     

## 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

目标：编写一个 Python 脚本，应用 API 缩短给定的 URL。

fromfutureimport with_statement

import contextlib

try:

from urllib.parse import urlencode

except ImportError:

from urllib import urlencode

try:

from urllib.request import urlopen

except ImportError:

from urllib2 import urlopen

import sys

def make_tiny(url):

request_url = ('tinyurl.com/api-create.…urlencode({'url':url}))

with contextlib.closing(urlopen(request_url)) as response:

return response.read().decode('utf-8')

def main():

for tinyurl in map(make_tiny, sys.argv[1:]):

print(tinyurl)

ifname== 'main':

main()

目标：创立一个揭示应用程序，在特定的工夫揭示你做一些事件 (桌面告诉)。

提醒：Time 模块能够用来跟踪揭示工夫，toastnotifier 库能够用来显示桌面告诉。

装置：win10toast

from win10toast import ToastNotifier

import time

toaster = ToastNotifier()

try:

print("Title of reminder")

header = input()

print("Message of reminder")

text = input()

print("In how many minutes?")

time_min = input()

time_min=float(time_min)

except:

header = input("Title of reminder\n")

text = input("Message of remindar\n")

time_min=float(input("In how many minutes?\n"))

time_min = time_min * 60

print("Setting up reminder..")

time.sleep(2)

print("all set!")

time.sleep(time_min)

toaster.show_toast(f"{header}",

f"{text}",

duration=10,

threaded=True)

while toaster.notification_active(): time.sleep(0.005)

目标：编写一个创立闹钟的 Python 脚本。

提醒：你能够应用 date-time 模块创立闹钟，以及 playsound 库播放声音。

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') ## download the alarm sound from link

break

目标：编写一个 Python 脚本，接管城市名称并应用爬虫获取该城市的天气信息。

提醒：你能够应用 Beautifulsoup 和 requests 库间接从谷歌主页爬取数据。

装置：requests，BeautifulSoup

from bs4 import BeautifulSoup

import requests

headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'}

def weather(city):

city=city.replace("","+")

res = requests.get(f'www.google.com/search?q={c…print("Searching in google......\n")

soup = BeautifulSoup(res.text,'html.parser')

location = soup.select('#wob_loc')[0].getText().strip()

time = soup.select('#wob_dts')[0].getText().strip()

info = soup.select('#wob_dc')[0].getText().strip()

weather = soup.select('#wob_tm')[0].getText().strip()

print(location)

print(time)

print(info)

print(weather+"°C")

print("enter the city name")

city=input()

city=city+"weather"

weather(city)

目标：编写一个 Python 脚本，能够检测图像中的人脸，并将所有的人脸保留在一个文件夹中。

提醒：能够应用 haar 级联分类器对人脸进行检测。它返回的人脸坐标信息，能够保留在一个文件中。

装置：OpenCV。

下载：haarcascade_frontalface_default.xml\

raw.githubusercontent.com/opencv/open…

import cv2

# Load the cascade

face_cascade = cv2.CascadeClassifier('haarcascade_frontalface_default.xml')

# Read the input image

img = cv2.imread('images/img0.jpg')

# Convert into grayscale

gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

# Detect faces

faces = face_cascade.detectMultiScale(gray, 1.3, 4)

# Draw rectangle around the faces

for (x, y, w, h) in faces:

cv2.rectangle(img, (x, y), (x+w, y+h), (255, 0, 0), 2)

crop_face = img[y:y + h, x:x + w]

cv2.imwrite(str(w) + str(h) + '_faces.jpg', crop_face)

# Display the output

cv2.imshow('img', img)

cv2.imshow("imgcropped",crop_face)

cv2.waitKey()

目标：编写一个 Python 脚本，将用户按下的所有键保留在一个文本文件中。

提醒：pynput 是 Python 中的一个库，用于管制键盘和鼠标的挪动，它也能够用于制作键盘记录器。简略地读取用户按下的键，并在肯定数量的键后将它们保留在一个文本文件中。

from pynput.keyboard import Key, Controller,Listener

import time

keyboard = Controller()

keys=[]

def on_press(key):

global keys

#keys.append(str(key).replace("'",""))

string = str(key).replace("'","")

keys.append(string)

main_string = "".join(keys)

print(main_string)

if len(main_string)>15:

with open('keys.txt', 'a') as f:

f.write(main_string)

keys= []

def on_release(key):

if key == Key.esc:

return False

with listener(on_press=on_press,on_release=on_release) as listener:

listener.join()
