Using Selenium in Python to save a webpage on Firefox

Question

I am trying to use Selenium in Python to save webpages on MacOS Firefox.

So far, I have managed to click COMMAND + S to pop up the SAVE AS window. However,

I don't know how to:

1. change the directory of the file,
2. change the name of the file, and
3. click the SAVE AS button.

Could someone help?

Below is the code I have use to click COMMAND + S:

ActionChains(browser).key_down(Keys.COMMAND).send_keys("s").key_up(Keys.COMMAND).perform()

Besides, the reason for me to use this method is that I encounter Unicode Encode Error when I :-

1. write the page_source to a html file and
2. store scrapped information to a csv file.

Write to a html file:

file_object = open(completeName, "w")
html = browser.page_source
file_object.write(html)
file_object.close() 

Write to a csv file:

csv_file_write.writerow(to_write)

Error:

UnicodeEncodeError: 'ascii' codec can't encode character u'\xf8' in position 1: ordinal not in range(128)

Answer 1

with open('page.html', 'w') as f:
    f.write(driver.page_source)
