Python Variable Scope With Examples Programiz 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
WHAT IS THE GLOBAL VARIABLE IN PYTHON QuickBoosters
What is a Global Variable in Python In Python a variable declared outside the function or in global scope is known as a global variable We can use global variables both inside and outside the function The scope of a global variable is broad It is accessible in all functions of the same module Python Global Variable PYnative. Example Changing Global Variable From Inside a Function using global global variable c 1 def add use of global keyword global c increment c by 2 c c 2 print c add Output 3 Run Code In the above example we have defined c as the global keyword inside add Then we have incremented the variable c by 2 i e c c 2 However this is how you would write the above in Python age 28 age is the variable name or identifier is the assignment operator 28 is the value assigned to the variable so 28 is the value of age The variable name is always on the left hand side and the value you want to assign goes on the right hand side after the
