Have you ever worked on uploading files in your projects?

Yes, file uploads are common in projects related to web development and automated testing. In my projects, I have worked with file uploads both as a user action (e.g., uploading documents through a form) and with automated testing of such scenarios using tools that simulate selecting and submitting files to a server.

Example of automating file upload with Selenium in Python:

from selenium import webdriver
from selenium.webdriver.common.by import By

browser = webdriver.Chrome()
browser.get('https://example.com/upload')

upload_input = browser.find_element(By.ID, 'file-upload')
upload_input.send_keys('/path/to/file.txt')

submit_button = browser.find_element(By.ID, 'submit')
submit_button.click()
