undefined variables

[Skaperen]

i run into this problem a lot. i'm writing a new script that does some major stuff like create lots of processes on my laptop for so purpose or downloads a bunch files or creates lots of a cloud resource. the script is done (roughly) and i want to test it out. but some of the call can be very dangerous if the script misbehaves. so what i like to do is comment out the dangerous functions for a while until i am sure it will call them appropriately. what i run into is that these calls were coded to assign results to a variable. when i comment the line,the variable is not assigned, later code that uses that variable will fail. in C at least the variable continues to exist even if it has a wrong value. i wish python had some way to easily deal with this on one line, keeping the variable but not doing the action.
