Finds a file with the supplied string in the folder of your choosing.

import os
text = input("input text : ")
path = input("path : ")
# os.chdir(path)
def getfiles(path):
    f = 0
    files = os.listdir()
    # print(files)
    for file_name in files:
        abs_path = os.path.abspath(file_name)
        if os.path.isdir(abs_path):
        if os.path.isfile(abs_path):
            f = open(file_name, "r")
            if text in
                f = 1
                print(text + " found in ")
                final_path = os.path.abspath(file_name)

6. Scrap and Download all images from the WEB Page

This script will utilize the selenium and beautifulsoup4 packages to download all photos from a specified webpage.


  1. We need to install selenium and beautifulsoup4 using pip python package manager pip install selenium beautifulsoup4 .
  2. Then download chrome driver as per your chrome browser version and OS from here —
  3. You have to enter the chromedriver path asked by the program.
from selenium import webdriver
import requests as rq
import os
from bs4 import BeautifulSoup
import time

# path= E:\web scraping\chromedriver_win32\chromedriver.exe
path = input("Enter Path : ")

url = input("Enter URL : ")

output = "output"

def get_url(path, url):
    driver = webdriver.Chrome(executable_path=r"{}".format(path))
    res = driver.execute_script("return document.documentElement.outerHTML")

    return res

def get_img_links(res):
    soup = BeautifulSoup(res, "lxml")
    imglinks = soup.find_all("img", src=True)
    return imglinks

def download_img(img_link, index):
        extensions = [".jpeg", ".jpg", ".png", ".gif"]
        extension = ".jpg"
        for exe in extensions:
            if img_link.find(exe) > 0:
                extension = exe

        img_data = rq.get(img_link).content
        with open(output + "\\" + str(index + 1) + extension, "wb+") as f:

    except Exception:

result = get_url(path, url)
img_links = get_img_links(result)
if not os.path.isdir(output):

for index, img_link in enumerate(img_links):
    img_link = img_link["src"]
    if img_link:
        download_img(img_link, index)
print("Download Complete!!")

Enter fullscreen mode Exit fullscreen mode

Executing the Script

To run the following script you have to open the terminal into the script’s root directory and need to enter the following command


Enter fullscreen mode Exit fullscreen mode

It will ask for the chrome driver path which you have just downloaded and a URL from which you want to download images.

7. Low Battery Notification

8. Calculate Your Age

This script prints your age in three different ways: Years, Months, Days

import time
from calendar import isleap

# judge the leap year
def judge_leap_year(year):
    if isleap(year):
        return True
        return False

# returns the number of days in each month
def month_days(month, leap_year):
    if month in [1, 3, 5, 7, 8, 10, 12]:
        return 31
    elif month in [4, 6, 9, 11]:
        return 30
    elif month == 2 and leap_year:
        return 29
    elif month == 2 and (not leap_year):
        return 28

name = input("input your name: ")
age = input("input your age: ")
localtime = time.localtime(time.time())

year = int(age)
month = year * 12 + localtime.tm_mon
day = 0

begin_year = int(localtime.tm_year) - year
end_year = begin_year + year

# calculate the days
for y in range(begin_year, end_year):
    if (judge_leap_year(y)):
        day = day + 366
        day = day + 365

leap_year = judge_leap_year(localtime.tm_year)
for m in range(1, localtime.tm_mon):
    day = day + month_days(m, leap_year)

day = day + localtime.tm_mday
print("%s's age is %d years or " % (name, year), end="")
print("%d months or %d days" % (month, day))

Enter fullscreen mode Exit fullscreen mode

Executing the Script

It is quite simple to execute the script!

Simply open a terminal in the folder containing your script and enter the following command:


Enter fullscreen mode Exit fullscreen mode

Then you have to enter the name and age

input your name: XYZ  
input your age: 33   
Output - XYZ's age is 33 years or 406 months or 12328 days

9. Organized download folder with different categories

This is a Python script that sorts files in the Download directory into other folders based on their extension.

import os
import shutil

#check number of files in  directory
files = os.listdir()

#list of extension (You can add more if you want)
extentions = {
    "images": [".jpg", ".png", ".jpeg", ".gif"],
    "videos": [".mp4", ".mkv"],
    "musics": [".mp3", ".wav"],
    "zip": [".zip", ".tgz", ".rar", ".tar"],
    "documents": [".pdf", ".docx", ".csv", ".xlsx", ".pptx", ".doc", ".ppt", ".xls"],
    "setup": [".msi", ".exe"],
    "programs": [".py", ".c", ".cpp", ".php", ".C", ".CPP"],
    "design": [".xd", ".psd"]
#sort to specific folder depend on extenstions
def sorting(file):
    keys = list(extentions.keys())
    for key in keys:
        for ext in extentions[key]:
            # print(ext)
            if file.endswith(ext):
                return key

#iterat through each file
for file in files:
    dist = sorting(file)
    if dist:
            shutil.move(file, "../download-sorting/" + dist)
            print(file + " is already exist")
            shutil.move(file, "../download-sorting/others")
            print(file + " is already exist")

10. Send Emails in Bulk From CSV File

This project includes a straightforward bulk email script that delivers the same message to a list of recipients.


This project only requires the Python standard library (more specifically, the csv, email, and smtplib modules).

import csv
from email.message import EmailMessage
import smtplib

def get_credentials(filepath):
    with open("credentials.txt", "r") as f:
        email_address = f.readline()
        email_pass = f.readline()
    return (email_address, email_pass)

def login(email_address, email_pass, s):
    # start TLS for security
    # Authentication
    s.login(email_address, email_pass)

def send_mail():
    s = smtplib.SMTP("", 587)
    email_address, email_pass = get_credentials("./credentials.txt")
    login(email_address, email_pass, s)
    # message to be sent
    subject = "Welcome to Python"
    body = """Python is an interpreted, high-level,
    general-purpose programming language.\n
    Created by Guido van Rossum and first released in 1991,
    Python's design philosophy emphasizes code readability\n
    with its notable use of significant whitespace"""

    message = EmailMessage()
    message['Subject'] = subject

    with open("emails.csv", newline="") as csvfile:
        spamreader = csv.reader(csvfile, delimiter=" ", quotechar="|")
        for email in spamreader:
            s.send_message(email_address, email[0], message)
            print("Send To " + email[0])

    # terminating the session

if __name__ == "__main__":

Enter fullscreen mode Exit fullscreen mode

Executing the Script

The script necessitates the use of two configuration files:

  • emails.csv should include the email addresses to which the message should be sent.
  • credentials.txt should include your SMTP server login credentials, with your user name and password on separate lines and no extra whitespace or decorations.

The project directory contains two sample files that you will almost certainly desire and need to alter.

Once you’ve got these files in place, all you have to do is

Enter fullscreen mode Exit fullscreen mode

11. Get the IP Address and Hostname of A Website

This script will be used to fetch the IP address and hostname of any website.

# Get Ipaddress and Hostname of Website
# importing socket library
import socket

def get_hostname_IP():
    hostname = input("Please enter website address(URL):")
        print (f'Hostname: {hostname}')
        print (f'IP: {socket.gethostbyname(hostname)}')
    except socket.gaierror as error:
        print (f'Invalid Hostname, error raised is {error}')

12. Terminal Progress Bar

Here I just take the example of image resizing for displaying the progress bar. when we convert lots of images at a time we can use the progress bar to show how many images are resized.


  • Library to show the progress bar
pip install tqdm

Enter fullscreen mode Exit fullscreen mode
  • Library to resize the images
pip install Pillow

Enter fullscreen mode Exit fullscreen mode
from tqdm import tqdm
from PIL import Image
import os
from time import sleep

def Resize_image(size, image):
    if os.path.isfile(image):
            im =
            im.thumbnail(size, Image.ANTIALIAS)
  "resize/" + str(image) + ".jpg")
        except Exception as ex:
            print(f"Error: {str(ex)} to {image}")

path = input("Enter Path to images : ")
size = input("Size Height , Width : ")
size = tuple(map(int, size.split(",")))


list_images = os.listdir(path)
if "resize" not in list_images:

for image in tqdm(list_images, desc="Resizing Images"):
    Resize_image(size, image)
print("Resizing Completed!")

13. Wifi Password Ejector

Get saved wifi password from your windows operating system

import subprocess

data = (
    subprocess.check_output(["netsh", "wlan", "show", "profiles"])
profiles = [i.split(":")[1][1:-1] for i in data if "All User Profile" in i]
for i in profiles:
    results = (
        .check_output(["netsh", "wlan", "show", "profile", i, "key=clear"])
    results = [b.split(":")[1][1:-1] for b in results if "Key Content" in b]
        print("{:<30}|  {:<}".format(i, results[0]))

16. Encrypt and Decrypt Texts

A small python program that encodes and decodes text.

$ Prerequisites

  • pycryptodome 3.9.8
  • Python 3
from Crypto.Cipher import AES
from Crypto import Random
from binascii import b2a_hex
import sys

# get the plaintext
plain_text = sys.argv[1]

# The key length must be 16 (AES-128), 24 (AES-192), or 32 (AES-256) Bytes.
