How to upload file with selenium (Python)?

import time
from selenium import webdriver

# Using Chrome to access web

# Open the website

time.sleep(3)
# Select the id Box

# Send id @R_618_4045@ion
id_Box.send_keys(parser['User']['id'])

# Find login button

# Find and click on list of user
user_button = driver.find_element_by_css_selector('#global_nav_profile_link')
