Ah, I think I see where you are coming from. I guess you aren’t intimately familiar with the HTTP protocol. There are various types of “headers” aka header fields, not only User-Agent, but Content-Type and others. When they suggest passing a User-Agent header, that actually means a call like
request.add_header("User-Agent", "custom text here")
using the exact string "User-Agent" as the field name (key).
If you can given a specific comment line to add to a specific example, that might be useful. Even if you aren’t 100% sure of the details :)
