Answer 1

According to the Requests documentation, you may add headers to the Session object as:

s = requests.Session()
s.auth = ('user', 'pass')
s.headers.update({'x-test': 'true'})

Answer 2

You aren't passing a dictionary, you're passing a string that looks like a dictionary. The solution is to create a proper dictionary and pass that in. Robot has a Create Dictionary keyword for this purpose.
