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 to 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.

In the first case the global keyword is pointless, so that is not correct. But drop the global keyword, and it is a correct usage. So is the second one. However, the most common usage for global variables are without using the global keyword anywhere.

  The global keyword is needed if you want to reassign the global variables in the function/method. Otherwise not.
