One of the many use cases of Python is task automation. Python provides several libraries for automating tasks, such as file manipulation, sending emails, and web browsing. In this lesson, we’ll explore some of the basics of task automation with Python.
Task automation is the use of software to reduce the manual handling of different tasks. In programming, this typically means writing software scripts that can automate repetitive tasks.
os
shutil
Python’s built-in os library can be used to perform tasks such as navigating the file system, retrieving file information, and modifying file data. The shutil library can be used for high-level file operations.
import os import shutil # List files and directories print(os.listdir()) # Change the current working directory os.chdir('/path/to/directory') print(os.getcwd()) # Copy file shutil.copy('source.txt', 'destination.txt')
selenium
The selenium library is a powerful tool for controlling a web browser through the program. It can automate real user behaviors such as clicking and scrolling.
from selenium import webdriver # Create a new instance of the Firefox driver driver = webdriver.Firefox() # Go to a webpage driver.get("http://www.google.com") # Find the search box element search_box = driver.find_element_by_name('q') # Type into the search box search_box.send_keys('Python') # Submit the form search_box.submit() # Close the browser driver.quit()
In this lesson, you’ve learned about how Python can be used to automate tasks. We’ve covered file and directory manipulation with the os and shutil libraries, and web browsing automation with the selenium library. Task automation is a powerful way to save time and effort on repetitive tasks.
