What is global and local variables

Answer 1

Lessons:
- Variables declared outside functions can be read in functions (they're globally-available), unless the function sets a variable by the same name...making that name local to the function (note the Exception).
- To set the global variable (which would otherwise immediately be local) you must declare your intention to set it with the word 'global'.

Answer 2

Simply:

A global variable is a variable that can be accessed anywhere in the code - any function etc.

A local variable is a variable that is 'exclusive' to that specific function, and can only be accessed within it- unless the value is returned...
