Question

Is it usually permissible for a local variable in one module to have the same name as a local variable in a different module?

Short answer

Answer: Yes, it is generally permissible for local variables in different modules to have the same name. This is because local variables' scope is limited to their respective modules and they will not collide or create naming conflicts. However, it is good practice to use descriptive variable names to avoid confusion.

Step-by-step solution

Understanding Local Variables

A local variable is a variable that is defined within a function, method, or other scoped code block. Its scope is limited to the block in which it is declared, meaning it can only be accessed and modified within that block.

Understanding Modules

A module is a collection of functions, classes, and variables in a separate file or group of related files. Modules are used to organize code and make it more readable and maintainable. In most programming languages, variables, functions, and classes inside a module have their own namespace and cannot directly access/collide with the namespace of other modules.

Local Variables in Different Modules

As local variables are limited to the scope of the block in which they are declared, it is generally permissible for local variables in different modules to have the same name. This is because each local variable's scope is limited to its respective module and they will not collide or create naming conflicts. However, it is good practice to use descriptive variable names that clearly indicate their purpose to avoid confusion when reading and maintaining your code.
