I didn’t get the concept of local and global variable. please explain briefly.
Local and global variable
Hello Shivam, first of all see the basic meaning of these words. Global means we can access that variable anywhere in the program and we need to define it globally and defining it globally means that we need to define it in global scope and local means that it can be under any function or the class and we are restricted to use in that scope only. And in case we need to use global variable inside the function or the class we can use the global keyword.
