Local variable is a variable, which can only be used inside the namespace it was defined. Global variable is a variable, which can be used anywhere in the program.

We strongly encourage using local variables, to improve readability and maintainability. Since local variables are almost immediately used after they are declared, we know with certainty that we will never have to makes references to that value in later sections of your code. They also naturally improve memory allocation, since they are quickly eligible for garbage-collection. Global variables are almost never a good idea because it violates encapsulation! Which as others pointed out is accesible everywhere.

x=54 def multiply(): return x*2 multiply () print (x) The X before the function is global while the X with the function is local. Hope that helps

Olorunsogo Abiodun because x is defined in the global scope,it is a global variable and so can be used anywhere,including functions
