Learning to have Class and doing stuff with it...

[bako]

PSA: Python noob trying to learn the whole module import, Class usage, and function creation stuff.

Error:
Traceback (most recent call last): File "waveshare.py", line 3, in <module> cmd(AT) NameError: name 'cmd' is not defined

=== Waveshare.py ===

import SIM800 cmd(AT)

=== SIM800/V25ter.py ===

import serial import time class V25ter(): def __init__(command): self.cmd = command def cmd(): print(command)

=== SIM800/__init__.py ===

import V25ter

"AT" is an example of a command that I want to send.

Not sure what you are trying to do, it seems that you want just to print the command to stdout;
To do this by the sophisticated way you chose, you need to do the following changes:

#=== SIM800/__init__.py === from .V25ter import V25ter #=== Waveshare.py === import SIM800 cmd_at = SIM800.V25ter("AT") cmd_at.cmd() #=== SIM800/V25ter.py === import serial import time class V25ter(): def __init__(self, command): self.cmd = command def cmd(self): print(self.cmd)

BTW, method cmd runs the command,
so its appropriate name should be, e.g. run?!

Hope that helps...

Ok, didn't know that. I changed it to run.

Did the changes, but now I have a new error...

Error:

Well... The end project is to convert/map a bunch of serial "AT" commands for the SIM800 chip to python along with simpler easy to use functions to do some of the common stuff. The print line is intended to be a serial.write() that uses the arguments of the defined function for variable options for the AT command. As far as I know there's two PIP packages for what I'm trying to do, but they seem dead and are not complete.
