Just want to know why str keyword is passed in isinstance() method?

def to_str(data):
  if isinstance(data, str):
    return data
  elif isinstance(data, bytes):
    return data.decode(‘utf-8’)
  else:
    raise TypeError(‘Must supply str or bytes, ‘ ‘found: %r’ % data)

I added code tags for you, read about bbcode
and use it on future posts
isinstance asks if the first argument is of the second arguments type,
in other words if data is a string then return it.

str isn't a keyword, it's a type. isinstance's second parameter, is a type (or class).
