A problem occurred while running a Python script. Here is the sequence of function calls leading up to the error, with the most recent (innermost) call first. The exception attributes are:
      __doc__ = 'Name not found globally.'
      __getitem__ = <bound method NameError.__getitem__ of <exceptions.NameError instance>>
      __init__ = <bound method NameError.__init__ of <exceptions.NameError instance>>
      __module__ = 'exceptions'
      __str__ = <bound method NameError.__str__ of <exceptions.NameError instance>>
      args = ("global name 'PermissionError' is not defined",)
