In Selenium how to give a name to a file when it is downloading

Question

I'm working with a Selenium script where I'm trying to download an Excel file and give it a particular name. I've written the code as well. 

Is there any way that I could give the file which is being downloaded a specific name?

Code:

#!/usr/bin/python
from selenium import webdriver
from selenium.webdriver.firefox.firefox_profile import FirefoxProfile

profile = FirefoxProfile()
profile.set_preference("browser.helperApps.neverAsk.saveToDisk", "text/plain, application/vnd.ms-excel, text/csv, text/comma-separated-values, application/octet-stream")
profile.set_preference("browser.download.dir", "C:\\Downloads" )
browser = webdriver.Firefox(firefox_profile=profile)

browser.get('https://test.com/')
browser.find_element_by_partial_link_text("Excel").click() # Download file
