Hey I've been working on a labyrinth game and I wrote a function to make the character (which is a robot) move. The problem is that Python says my function is not define
NameError: name 'move' is not defined
but I defined it and I imported the function file in the main file.
This is my function file (modified so it's a little bite cleaner)
import pickle
from classes.labyrinthe import *
from roboc import *
from carte import *
from creer_labyrinthe import *
def move(oldLab, direction, steps):
global isOnExit
...
return oldLab
And this is my main file (again modified...)
import os
from classes.carte import Carte
from fonctions.receiveRobotMoves import *
from fonctions.move import *
...
isOnExit = False
while isOnExit == False: #Tant que le robot n'est pas sur la sortie...
#On demande au joueur la direction qu'il veut prendre
receiveRobotMoves()
#On fait avancer le robot
conteneur = move(Labyrinthe, movesInformation['direction'],
movesInformation['steps'])
#On met à jour le labyrinthe
Labyrinthe = conteneur
Could you please tell me what I can do to make it work.

I was working with fernet to encrypt. In the tests I founded that if I change the last character of the key, fernet it is able to dencrypt.
For example if the key is ZwvCXUGvnG0RvkhNszIQsQOqz8yaKjUSJpxraDVsxd4= and i type ZwvCXUGvnG0RvkhNszIQsQOqz8yaKjUSJpxraDVsxd5= instead, the program dencrypt my code. I founded this error bc i was lazy to copy a whole new key, so i decided to only change the last character. This happen with every consecuent character in the last one character of the key.
If anyone could help me i would be very thankfull

If I launch this script on a console it works perfectly. I need but I can't launch it at boot in the rc.local.
....
if [ "$_IP" ]; then
printf "My IP address is %s\n" "$_IP"
fi
python /home/pi/thermostat.py &
exit 0
This don't work and I don't understand what happen ?! (I launched other scripts in rc.local whithout any problem)
Does someone has an idea to help me ???
Thanks in advancecd
This is because the python script will get killed when the script that started it exits even if it is pushed to the background with &.
The hacky solution is to prefix the command with nohup (which means the process will not get sent the Hang Up signal when the parent script exits).
The better option would be to write a proper systemd service definition for your script.

I'm using socket in python between 2 laptop to send informations. But I have an error and i can't resolve it. (I'm a debutant in python). The problem is when i trierd to send information with send() function
Traceback (most recent call last):
File "client.py", line 60, in <module>
client.send(GetMyInfo.scan())
TypeError: send() argument 1 must be string or buffer, not None
Maybe the error is due my function Getinfo ?
I'm using a class with functions (listinfo() here).
Thx
