Correct Use Of Global Variables In Python 3

In the first case the global keyword is pointless, so that is not correct. Defining a variable on the module level makes it a global variable, you don’t need the global keyword.

The second example is correct usage.

However, the most common usage for global variables are without using the global keyword anywhere. The global keyword is needed only if you want to reassign the global variables in the function/method.
