Using Python Syntax in Configuration Files
As a rule it thumb, it's best to place as many configuration options in a configuration file. This way you don't need to edit/compile the code to change its behavior.
However writing a parser for configuration files takes time, and the standard ones (.ini and .xml) have their limitations. Lucky for us each Python program comes with the full interpreter bundled. We can do stuff like:
Then using

from sys import platform
if platform == "win32":
APP_HOME = "c:\\my_cool_app"
else:
APP_HOME = "/opt/my_cool_app"
Then using
__import__
in our application we can load the configuration file and parse it without a sweat:
# my_cool_app.py
settings = __import__("settings.py")
print settings.APP_HOME

"Hard" breakpoints in Python
Sometimes, when debugging, you want a to stop at abreakpoint no matter what.
Use the following code:
When you run the script with python (not with
BTW: You can do the same trick on MSVC if you write
Use the following code:
from pdb import set_trace
def buggy_function():
pass
pass
set_trace() # Break here
pass
pass
if __name__ == "__main__":
buggy_function()
When you run the script with python (not with
pdb
), set_trace
will cause the program to stop at this line and pdb
console will show.BTW: You can do the same trick on MSVC if you write
__asm int 3
