问题
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

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. :)

I had the same issue, and for me it happened when I moved the class file, but I left a .pyo file in the old folder, and python was still reading that .pyo file instead of reading the moved .py file.

Very old question, but I quote @Jacquot 's comment since it solved my problem (I was using %autoreload in ipython).
For what it's worth, it can also happen when using the %autoreload magic command in jupyter notebook, when you modify some methods in your module code (ipython.org/ipython-doc/3/config/extensions/…)
In particular, I solved the problem re-running the cell that was importing my class.

Faced the same issue until I realized I had named the classes in both the files with the same name - pretty dumb!
