Can't subclass SevenSegment?

[jakekarnes42]

Hi rolfyone,

Did you run the setup script? Check the readme for this project. There are a few steps (assuming Debian system):

1. sudo apt-get update
2. sudo apt-get install build-essential python-dev
3. sudo apt-get install python-smbus python-imaging
4. sudo python setup.py install

Possibly you missed step 4?

Other than that, I would double check that the code you provided from memory really matches up with the code you are trying to execute.

I've definitely run step 4. I've got anther script that is using the same import and working (without subclassing) just using SevenSegment like in the example script.
I was trying to encapsulate setting other aspects of the metacharacter (center colon, left colon dots) within this subclass, as well as having it write a 12 hour clock... Maybe I should just hack it straight into seven segment i guess, I just figured that subclassing would let me implement all the bits i need without updating the library initially and having to make install all the time...

Give this a try:

from Adafruit_LED_Backpack import SevenSegment

class ClockDisplay(SevenSegment.SevenSegment):
   ...

If that doesn't help, please include the error message.

Thanks for that, that was precisely the problem! I'm sorry to raise an issue and it was something silly :( I was assuming it was something I was doing wrong...
