Use tuple of prefixes, use requests to encode params

[g-mc]

• Use tuple of prefixes in str.startswith (instead of two separate calls)

  Return True if string starts with the prefix, otherwise return False. prefix can also be a tuple of prefixes to look for.

  >>> input_source = 'http://www.google.com'
  >>> input_source.startswith('http://') or input_source.startswith('https://')
  True
  >>> input_source.startswith(('http://', 'https://'))
  True
  >>> input_source = 'https://www.google.com'
  >>> input_source.startswith('http://') or input_source.startswith('https://')
  True
  >>> input_source.startswith(('http://', 'https://'))
  True

• Use requests to encode & pass in parameters (instead of manually building the url)
