pythonattributeerror

Getting an AttributeError: <class> has no attribute <method>

I am creating a method in a class in a module mod1 and calling it as follows:

class blahblah:
   def foobar(self, bvar, **dvar)
       ////
       return dvar

And calling it as:

obj1 = mod1.blahblah()
dvar1 = obj1.foobar(True, **somedictionary)

It throws a Attribute error: blahblah has no attribute named foobar

Could you please help me with it? Thanks in advance

Solution

  • The type of error you describe can be caused simply by mismatched indentation. If the method is at the very bottom of your class, move it up in the class a bit and the problem will become apparent.

    When python interpreters run into mismatched indents (like say you started using tabs at the bottom of a file that was indented with spaces), the interpreter will not always throw an error; it can simply ignore the rest of the file. I ran into this just today while updating some old code where the original author used different whitespace chars (that happened to match my Geany tabs), and it threw me for a loop for a lot longer than I'd like to admit. :)
