Send out press notifications to any platform from any again stop. Batch
while in the function definition. The worldwide assertion doesn't have for being originally in the purpose definition, but that's wherever it is check my site generally positioned. Anywhere it is placed, the global declaration would make feed a world variable almost everywhere
Thus it tends to make more substantial courses harder to comprehend. By preventing mutating globals, In the long term your code is going to be a lot easier to understand, examination and keep.
