Actual behavior

class pc(object):
    def __init__(self, pcname, model):
        self.pcname = pcname
        self.model = model

    def print_name(self):
        print('Workstation name is', self.pcname, 'model is', self.model)

• Format document
• befor def formatter set blank line
• python get error

>>>     def print_name(self):
  File "<stdin>", line 1
    def print_name(self):
    ^
IndentationError: unexpected indent

Expected behavior

If I remove blank line or set space, code run without error
