My import not working

[man_in_the_hill]

Hi Everybody

I am trying to learn python and I created my first script with a package that contains an imported module but it does not work!
Both scripts work independently. 

I put the package in the site-packages of the virtualenv and no import.
I tried many things but nothing worked and I understood how the import works!

I do not understand why it does not work! Can you help me please ?

Thanks a lot


My OS: Debian 8 KDE
IDE: PyCharm also Vim + terminal
Virtualenv: Python 3.5
My Working directory: PycharmProject
My sys.path with Pycharm:

>>> import sys
>>> sys.path
['/home/user/bin/PYTHON/pycharm-community-2016.2.3/helpers/pydev', '/home/user/bin/PYTHON/PycharmProject', '/home/user/bin/PYTHON/pycharm-community-2016.2.3/helpers/pydev', '/home/user/bin/PYTHON/virtualenv/py35/lib/python35.zip', '/home/user/bin/PYTHON/virtualenv/py35/lib/python3.5', '/home/user/bin/PYTHON/virtualenv/py35/lib/python3.5/plat-linux', '/home/user/bin/PYTHON/virtualenv/py35/lib/python3.5/lib-dynload', '/usr/local/lib/python3.5', '/usr/local/lib/python3.5/plat-linux', '/home/user/bin/PYTHON/virtualenv/py35/lib/python3.5/site-packages', '/home/user/bin/PYTHON/PycharmProject']

The Two littles scripts:

The main script:

You're missing the most important part. Please post your error trace.

Thanks

Thanks ! Sorry ...

envoi_mon_courier seems to be a method of class MonCourier...
So you should call it with
MonCourier.envoi_mon_courier("ALERTE ! {}G de disponible sur le disk !".format(valeur))

Hello,

You need to start reading the error messages, they will always tell you what's wrong (with blatant errors).
The trace shows the last few commands that were executed, and the final one shows the line where the system crashed.

NameError: name 'envoi_mon_courier' is not defined

This certainly is at least issue number 1.

it requires the name that you assigned to the import:

MonCourier.envoi_mon_courier
