Include files

Is there any way to include another python files in the main program, for example i've two files in python and i want to share the functions between them.

You use the import statement, like with any module. The code will be imported into its own namespace, and any top-level code will be executed.

To import into the same namespace, use the 'from your_module import your_things' construct.

Seems that this does not work, i''ve

from pfornumb.py import *

if __name__ == '__main__':
print "Hola mundo"


and I get this

Traceback (most recent call last):
File "pruimp.py", line 4, in ?
from pfornumb.py import *
ImportError: No module named pfornumb.py

The error your getting means that Python can't find the file you want to import.. In order for you to import a module into Python it must be on Python's search path (sys.path).

If the pfornumb.py isn't in the same location as your main program you will need to move it. The import statment doesn't use the files extension i.e .py so it should look like this .

from pfornumb import *

alternatively it could look like this

import pfornumb

After Python imports a module for the first time (of if the files changed) it compiles it to Python bytecode (.pyc), this is more a speed thing than anything else. Don't be comfused if you suddenly knowtice a .pyc file a long with your .py files.

To check what's your your search path you can do somthing like this .

>>> import sys
>>> sys.path
['C:\\PYTHON23\\Lib\\idlelib', 'C:\\WINDOWS\\SYSTEM\\PYTHON23.zip', 'C:\\Python23', 'C:\\PYTHON23\\DLLs', 'C:\\PYTHON23\\lib', 'C:\\PYTHON23\\lib\\plat-win', 'C:\\PYTHON23\\lib\\lib-tk', 'C:\\PYTHON23\\lib\\site-packages']

I hope this helps ,

Have fun,

Actually, your problem is that you had a .py in the import statement.
You don't need the .py.
import q.py #WRONG
import q #RIGHT

Didn't i just say that Mamba .



I just chose to explain what was going on as well as how to fix it

And how to ADD a new path to SYS PATH ? I tried :

sys.path += "\\TEMP"

and it did not work - it added each letter one by one to the path (T,E,M,P) instead of adding TEMP

sys.path is a list, so try:

Thanks - the APPEND worked fine
