A variable defined inside a function and it can only be used/called within this function. Calling this variable outside of the function it is defined in will lead to an error. This is an important idea in Python, as new users are frequently confused over the scope of defined variables.

Local Variable

Any variable defined outside of a function is a global variable. Its value is accessible inside of and outside of any function. Global variables are overridden by local variables if given the same name, meaning in a function, the local variable will be called rather than the global one.
