> Obviously, you can't put every variable on the 'def' line. Obviously. Or at least maybe not. If your program is well designed its unusual to have more that a few global varoables so you could in fact pass them in to each fuinctrion - but thats bad practice too.
You shouldn't ever have to. If you access every variable in every function (or even in one function!) then there is something fundamentally wrong with your design. In an ideal world: Functions should be designed to be highly cohesive - meaning all the things inside are related to each other - and loosely coupled - meaning they don't rely on a lot of data being passed between them. Functions should also have few side-effcts - they shouldn't alter global variables - and should be predictable and stateless - meaning calling the same function with the same arguments should return the same results each time. Following these rules should result in code that is more reliable, more maintainable and easier to reuse. > utility of some sort that will present me with a list of the variables used > in an application? dir() will tell you what names exist in the namespace of the argument.
