I'm going crazy here. I'm facing a problem that should have been solved by logic already. The problem is this:

I have two folders:

novapasta /
novapasta / classes

In the first folder there is a file:

novapasta / main.py

In the second folder, there are two files:

novapasta / classes / classPrint.py
novapasta / classes / classGerar.py

The logic is as follows:

I open the main.

Main imports class classPrint

class classPrint imports class classGenerate

So far so good. In the main.py file is the following:

    from classes import classPrint
    objeto = classPrint.printar()
    print(objeto.b)

In the classPrint file is this code:

    import classGerar
    objeto = classGerar.Gerar()
    class printar():
        b = objeto.a

The problem is that classPrint can not import the classGerate. Both classes are in the same folder. But one can not import the other.

obs: If I put main.py in the same class folder. A main works correctly.

Has anyone ever faced this problem and knows the solution?

Within the classes directory create a file named "__init__.py" with the following content:

from classPrint import printar

This will tell Python that the classes directory has a bunch of modules and then you can use from classes import classPrint inside "main.py".

The solution is as follows:

create a folder called the Generate folder and put the classGerrar.py inside   her.

in the classPrint file change the first line to: "from .pastaGerar   import classGerate "

That blessed one. before theGerar folder makes a lot of difference. I just do not   I understand why I can not put these classes all in the same   folder.

I found a better solution. Go in classPrint.py and replace "import classGerar "by" from. import classGerate "

You do not even have to create a subfolder for the classGenerate. Just change that line.
