Python global and user config variables + git. The idea behind this is that you have one central place to keep config variables with the option of having user-specific variables outside of user control. Useful for working with API keys and other sensitive data. Simply put user-specific variables in config_user.py.

.gitignore

config_user.py

config.py

secretKey = ""

try:
  from config_user import *
except ImportError:
  pass # Could not find user config

config_user.py

# Contains user-specific config variables

secretKey = "MY SUPER SECRET KEY"

main.py

import config

print "The secret key is: " + config.secretKey

Great, thanks Val! Is there a reason you put the import functionality in config.py, as opposed to in main.py?
