Completed Exercise Python Global Variables Variables that are created outside of a function (as in all of the examples in the previous pages) are known as global variables. global variables can be used by everyone, both inside of functions and outside. create a variable outside of a function, and use it inside the function. A variable created in the main body of the python code is a global variable and belongs to the global scope. global variables are available from within any scope, global and local.

This video explains how global variables work in python. part of a series of video tutorials to learn python for beginners! more. The global keyword in python is used to modify a global variable in a local context (as explained here). this means that if the op modifies some constant within myfunc the change will affect also outside the function scope (globally). In python, global variables are declared outside any function and can be accessed anywhere in the program, including inside functions. on the other hand, local variables are created within a function and are only accessible during that function’s execution. If you want to refer to a global variable in a function, you can use the global keyword to declare which variables are global. you don't have to use it in all cases (as someone here incorrectly claims) if the name referenced in an expression cannot be found in local scope or scopes in the functions in which this function is defined, it is. Variables are containers for storing data values. python has no command for declaring a variable. a variable is created the moment you first assign a value to it. variables do not need to be declared with any particular type, and can even change type after they have been set.
