Re: "once" assigment in Python

This is one of the things that I often see people trying to do in Python, where the best solution is simply to understand how Python works and craft the code to work with the language.

"once" assigment in Python

Hello, I've been using Python for some DES simulations because we don't need full C speed and it's so much faster for writing models. During coding I find it handy to assign a variable *unless it has been already assigned*: I've found that this is often referred to as "once" assigment. The best
