How to create a module?

[psbasha]

Hi ,


I have set of Python files,How to make that Python files as module?.

Is it compulsory that we have to make all the python files as module?.What I understood about module in python is that ,it is similar to Library and DLL in programming languages.

When we have to say that we have to create a Module?


Thanks in advance

You misunderstand your terminology:
Each .py file is a "module".
Modules may be put into a directory with an __init__ file to make a package.
You have been given links to PI and py2exe previously. Please see the posts by truelove911 in the python>articles section of this forum (links in the announcement and in the sticky above).

Thanks for the reply.

I have to read on modules to know more about it.

It's not as complex as you might think. Here is a partial directory listing for my 'modules'.:

Directory of C:\SDS2_7.0\macro\macrolib\
 
__init__.py
__init__.pyc
angle.py
angle.pyc
AngleBetMemTrue.py
AngleBetMemTrue.pyc
Basis3D.py
Basis3D.pyc
beam_point_list.py
...........................

Most of these files can be run as stand-alone scripts with this code:

if __name__ == '__main__':
    ....execute the function or class defined in this file........

To import a function or class from a module:

    from macrolib.Basis3D import BasisTransToGlobal

The parent directory to macrolib must be on the system path.

Hi,

In my project I am creating each class ( they have minimum 500 to 1000 LOC) as different python file ( .py).But as per discussion in the forum ,each python file is called as a module.

I would like to know whether I am proceeding in a right direction.

Sample1.py

class Sample1:
.......

Sample2.py

class Sample2:
.......

Samplen.py

class Samplen:

Is the above approach is right?. or is there any best way to handle the approach.

Thanks in advance

Generally, it is OK to have one class per module. Naming as you have suggested can become a little confusing for beginners, but is valid and often used. ie:

import samle1
mySampleObject = sample1.sample1()

For encapsulation with the Model/View/Control model in mind, I usually end up with low level (model) class(es) and functions in one module that will run without any GUI. Then build the GUI (View/Control) on top of that work in a separate module. Ultimately, there is one module to get the whole thing running, with separate modules importing the classes and functions that they need. Keep and eye on the Code sub section of this forum for updates soon.

There is no reason why each class has to be in a separate file. I prefer to name the module file different than the functions and class defined in it. I would:

from samples import Sample1, Sample2, Samplen, sampler, .........

That's just my preference.
