Variables defined in the local scope are only accessible within that function and are destroyed once the function completes execution. Local variables have the highest priority in accessing over global variables of the same name. def func(): x = 10 print(x) func() -- the variable x is defined inside the function, and it can only be accessed within the function. #3 Global variable -- global variable means variable which is defined outside the function -- we can access the global variable inside the function -- we can access the global variable outside the function x = 10 def func(): print(x) func() -- the variable x is defined outside the function, and it can be accessed within the function. #4 Global keyword -- if we want to access the global variable inside the function and we want to change the value of global variable inside the function then we have to use global keyword. x = 10 def func(): global x x = 15 print(x) func() -- in this case no new variable is created inside the function, but the global variable x is accessed and modified inside the function. #5 Global() function -- if we want to access the global variable inside the function and we want to change the value of global variable inside the function then we have to use global() function. e.g x = 10 def func(): x = 15 print("local x: ",x) y = globals()['x'] print("global x: ",y) globals()['x'] = 20 -- using globals()['x'] we can access the global variable x inside the function and we can change the value of global variable x inside the function.
