Explain the difference between local and global variables
The difference is the scope. A local variable can only be seen within its scope, for example a variable defined in a method can only be seen within this method. However, a global variable can be seen by everything within the program.y = 1 def foo(): x = 5 def bar(): print(x) # Doesn't work print(y) # Prints 1
