Class Modules, and Passing Variables: Seeking Advice

[Robo_Pi]

What I posted earlier is correct.
You have changed it.

it should read:

import AlyshaPass
task = AlyshaPass.AlyshaPass()

the whenever you are calling a method in AlyshaPass, use

task.read()

Thanks for the suggestion.

I prefer to use names that have meaninging for me.

So I have chosen to rewrite my main program as follows:

1. First I've changed main() to Alysha() because that's what I want this to be called.
   
2. I took your advice and used the specific import format.
   
3. I then set the class name to the pointer AlyshaPass
   
4. I'm using title case for this to remind me that this is pointing to a class
   
5. This removes the need to use parentheses after AlyshaPass in the actual calls.
   
6. I don't want to use just "ap", or "task" for this pointer because I'll forget what that means.
   
7. When I see AlyshaPass.something I'll know that this is pointing to the AlyshaPass() class.
   
8. According to PEP 8 style convention class names are supposed to be capitalized.
   

So I'm very happy with this code as written below and it seems to work just fine.

from alysha_pass.AlyshaPass import AlyshaPass
AlyshaPass = AlyshaPass()


def Alysha():
		# get tasks
	tasks = AlyshaPass.read()
	print tasks
		
		# write reply
	AlyshaPass.write("Dummy Message")
	
	
		# for documentation purposes
	help(AlyshaPass.read)
	help(AlyshaPass.write)
	
		# Just a temporary break for debugging
	a = int(raw_input("Press enter:"))
	
	return 0
if __name__ == '__main__':
	Alysha()

Just in case anyone is interested in the full project here's the modified AlyshaPass.py module

Just as a heads-up I've changed the following items:

1. The text file I'm working with is now called tasks.txt (formerly commands.txt)
   
2. The file_path and name are also now defined in Alysha() and passed to AlyshaPass.read()
   
3. In the actual read() method I'm made some major changes.
   
4. The main change was to add the ability to pass in the file_path.
   
5. Basically I do everything on a single line now (line 37 in the code below)
   
6. I've also renamed the variables to "words" instead of "tasks"
   
7. The reason for this is that I now see where I can make this a more generalized method.
   
8. Also hopefully everything has been cleaned up to meet PEP 8 style conventions.
