Convert spaces to %20 in list

I would recommend using urllib.parse module and its quote() function. https://docs.python.org/3.6/library/urllib.parse.html#urllib.parse.quote Example for Python3:

from urllib.parse import quote
text_encoded = quote(t.text)

Note: using quote_plus() won't work in your case as this function replaces spaces by plus char.

Use the String.replace() method as described here: http://www.tutorialspoint.com/python/string_replace.htm

So for t.text, it would be t.text.replace(" ", "%20")
