Scrape YouTube search suggestions into list - see details!

I'm looking for you to scrape a list for me of YouTube search suggestions on a particular topic. When you type this search query: "download a" YouTube will bring up 10 suggestions. Further if you type "download ab" it will bring up 10 more search suggestions. YOUR TASK: I need you scrape all these suggestions for all permutations of "download a", "download aa", "download ab", "download ac", "download ad" all through the alphabet until "download az" Then when are done with "download a" you move to "download b", "download ba", "download bb", "download bc", "download bd" - "download bz" ETC ETC You should scrape a big list of suggestions from all the permutations of the alphabet, even until "download zz". Note: Some permutations such as "download bz" will not have any suggestions. Which is ok, but you should know this in case it can mess up your scraping. The list should be complied into 1 suggestion per line, in .txt and also a spreadsheet.
