Namespaces

Namespaces are a logical way to organize variable names, to allow a variable inside a function or an imported module to share the same name as a variable in the main script body, without overwriting the variable. Referred to as "local" variables versus "global" variables, local variables are contained within a function (either in the script or within an imported module), while global variables are within the main body of the script.

These issues often arise when a variable within an imported module unexpectedly has the same name of a variable in the script, and the interpreter has to use namespace rules to decide between the two variables.
