在本文中，我编译了 25 个 Python 程序的集合。

我已包含链接以了解有关每个脚本的更多信息，例如 packages installation和 how to execute script?.

1. 将 JSON 转换为 CSV

import json
if __name__ == '__main__':try:with open('input.json', 'r') as f:data = json.loads(f.read())output = ','.join([*data[0]])for obj in data:output += f'\n{obj["Name"]},{obj["age"]},{obj["birthyear"]}'with open('output.csv', 'w') as f:f.write(output)except Exception as ex:print(f'Error: {str(ex)}')

2. 密码生成器

import random
import string
total = string.ascii_letters + string.digits + string.punctuation
length = 16
password = "".join(random.sample(total, length))
print(password)

3. 从多个文件中搜索字符串

import os
text = input("input text : ")
path = input("path : ")
# os.chdir(path)
def getfiles(path):f = 0os.chdir(path)files = os.listdir()# print(files)for file_name in files:abs_path = os.path.abspath(file_name)if os.path.isdir(abs_path):getfiles(abs_path)if os.path.isfile(abs_path):f = open(file_name, "r")if text in f.read():f = 1print(text + " found in ")final_path = os.path.abspath(file_name)print(final_path)return Trueif f == 1:print(text + " not found! ")return Falsegetfiles(path)

4. 从给定网页获取所有链接

import requests as rq
from bs4 import BeautifulSoupurl = input("Enter Link: ")
if ("https" or "http") in url:data = rq.get(url)
else:data = rq.get("https://" + url)
soup = BeautifulSoup(data.text, "html.parser")
links = []
for link in soup.find_all("a"):links.append(link.get("href"))# Writing the output to a file (myLinks.txt) instead of to stdout
# You can change 'a' to 'w' to overwrite the file each time
with open("myLinks.txt", 'a') as saved:print(links[:10], file=saved)

key = b'this is a 16 key'# Generate a non-repeatable key vector with a length
# equal to the size of the AES block
iv = Random.new().read(AES.block_size)# Use key and iv to initialize AES object, use MODE_CFB mode
mycipher = AES.new(key, AES.MODE_CFB, iv)# Add iv (key vector) to the beginning of the encrypted ciphertext
# and transmit it together
ciphertext = iv + mycipher.encrypt(plain_text.encode())# To decrypt, use key and iv to generate a new AES object
mydecrypt = AES.new(key, AES.MODE_CFB, ciphertext[:16])# Use the newly generated AES object to decrypt the encrypted ciphertext
decrypttext = mydecrypt.decrypt(ciphertext[16:])# output
file_out = open("encrypted.bin", "wb")
file_out.write(ciphertext[16:])

21. 创建一个简单的秒表

import tkinter as Tkinter
from datetime import datetime
counter = 0
running = Falsedef counter_label(label):def count():if running:global counter# To manage the intial delay. if counter == 0:display = 'Ready!'else:tt = datetime.utcfromtimestamp(counter)string = tt.strftime('%H:%M:%S')display = stringlabel['text'] = display# label.after(arg1, arg2) delays by # first argument given in milliseconds # and then calls the function given as second argument. # Generally like here we need to call the # function in which it is present repeatedly. # Delays by 1000ms=1 seconds and call count again. label.after(1000, count)counter += 1# Triggering the start of the counter. count()# start function of the stopwatch
def Start(label):global runningrunning = Truecounter_label(label)start['state'] = 'disabled'stop['state'] = 'normal'reset['state'] = 'normal'# Stop function of the stopwatch
def Stop():global runningstart['state'] = 'normal'stop['state'] = 'disabled'reset['state'] = 'normal'running = False# Reset function of the stopwatch
def Reset(label):global countercounter = 0# If reset is pressed after pressing stop. if not running:reset['state'] = 'disabled'label['text'] = '00:00:00'# If reset is pressed while the stopwatch is running. else:label['text'] = '00:00:00'root = Tkinter.Tk()
root.title("Stopwatch")# Fixing the window size.
root.minsize(width=250, height=70)
label = Tkinter.Label(root, text='Ready!', fg='black', font='Verdana 30 bold')
label.pack()
f = Tkinter.Frame(root)
start = Tkinter.Button(f, text='Start', width=6, command=lambda: Start(label))
stop = Tkinter.Button(f, text='Stop', width=6, state='disabled', command=Stop)
reset = Tkinter.Button(f, text='Reset', width=6, state='disabled', command=lambda: Reset(label))
f.pack(anchor='center', pady=5)
start.pack(side='left')
stop.pack(side='left')
reset.pack(side='left')
root.mainloop()

22. Python脚本压缩文件夹和文件

import zipfile
import sys
import os# compress file function
def zip_file(file_path):compress_file = zipfile.ZipFile(file_path + '.zip', 'w')compress_file.write(path, compress_type=zipfile.ZIP_DEFLATED)compress_file.close()# Declare the function to return all file paths of the particular directory
def retrieve_file_paths(dir_name):# setup file paths variablefile_paths = []# Read all directory, subdirectories and file listsfor root, directories, files in os.walk(dir_name):for filename in files:# Create the full file path by using os module.file_path = os.path.join(root, filename)file_paths.append(file_path)# return all pathsreturn file_pathsdef zip_dir(dir_path, file_paths):# write files and folders to a zipfilecompress_dir = zipfile.ZipFile(dir_path + '.zip', 'w')with compress_dir:# write each file separatelyfor file in file_paths:compress_dir.write(file)if __name__ == "__main__":path = sys.argv[1]if os.path.isdir(path):files_path = retrieve_file_paths(path)# print the list of files to be zippedprint('The following list of files will be zipped:')for file_name in files_path:print(file_name)zip_dir(path, files_path)elif os.path.isfile(path):print('The %s will be zipped:' % path)zip_file(path)else:print('a special file(socket,FIFO,device file), please input file or dir')

23. 查找 IMDB 评级

from bs4 import BeautifulSoup
import requests
import pandas as pd
import os# Setting up session
s = requests.session()  # List contaiting all the films for which data has to be scraped from IMDB
films = []# Lists contaiting web scraped data
names = []
ratings = []
genres = []# Define path where your films are present
# For eg: "/Users/utkarsh/Desktop/films"
path = input("Enter the path where your films are: ")# Films with extensions
filmswe = os.listdir(path)for film in filmswe:# Append into my films list (without extensions)films.append(os.path.splitext(film)[0])# print(os.path.splitext(film)[0])for line in films:# x = line.split(", ")title = line.lower()# release = x[1]query = "+".join(title.split()) URL = "https://www.imdb.com/search/title/?title=" + queryprint(URL)# print(release)try: response = s.get(URL)#getting contect from IMDB Websitecontent = response.content# print(response.status_code)soup = BeautifulSoup(response.content, features="html.parser") #searching all films containers foundcontainers = soup.find_all("div", class_="lister-item-content")for result in containers:name1 = result.h3.a.textname = result.h3.a.text.lower()# Uncomment below lines if you want year specific as well, define year variable before this # year = result.h3.find(# "span", class_="lister-item-year text-muted unbold"# ).text.lower() #if film found (searching using name)if title in name:#scraping ratingrating = result.find("div",class_="inline-block ratings-imdb-rating")["data-value"]#scraping genregenre = result.p.find("span", class_="genre")genre = genre.contents[0]#appending name, rating and genre to individual listsnames.append(name1)ratings.append(rating)genres.append(genre)except Exception:print("Try again with valid combination of tile and release year")#storing in pandas dataframe
df = pd.DataFrame({'Film Name':names,'Rating':ratings,'Genre':genres}) #making csv using pandas
df.to_csv('film_ratings.csv', index=False, encoding='utf-8')

24. 网络爬虫 Youtube 评论

from selenium import webdriver
import csv
import timeitems=[]
driver=webdriver.Chrome(r"C:/Users/hp/Anaconda3/chromedriver.exe")driver.get('https://www.youtube.com/watch?v=iFPMz36std4')driver.execute_script('window.scrollTo(1, 500);')#now wait let load the comments
time.sleep(5)driver.execute_script('window.scrollTo(1, 3000);')username_elems = driver.find_elements_by_xpath('//*[@id="author-text"]')
comment_elems = driver.find_elements_by_xpath('//*[@id="content-text"]')
for username, comment in zip(username_elems, comment_elems):item = {}item['Author'] = username.textitem['Comment'] = comment.textitems.append(item)
filename = 'C:/Users/hp/Desktop/commentlist.csv'
with open(filename, 'w', newline='', encoding='utf-8') as f: w = csv.DictWriter(f,['Author','Comment']) w.writeheader() for item in items: w.writerow(item)

25. 文字转语音

from gtts import gTTS
import os
file = open("abc.txt", "r").read()speech = gTTS(text=file, lang='en', slow=False)
speech.save("voice.mp3")
os.system("voice.mp3")
