Python Variable Scope In Python we can declare variables in three different scopes local scope global and nonlocal scope A variable scope specifies the region where we can access a variable For example def add numbers sum 5 4 Here the sum variable is created inside the function so it can only be accessed within it local scope Python Variable Scope With Examples Programiz. The variable s is defined as the global variable and is used both inside the function as well as outside the function Note As there are no locals the value from the globals will be used but make sure both the local and the global variables should have same name Why do we use Local and Global variables in Python To create a global variable inside a function you can use the global keyword Example If you use the global keyword the variable belongs to the global scope def myfunc global x x fantastic myfunc print Python is x Try it Yourself Also use the global keyword if you want to change a global variable inside a function Example
