How to page through results using Shopify Python API wrapper

As mentioned by @babis21, this was a bug in the shopify python api wrapper. The library was updated in January of 2020 to fix it.

For anyone stumbling upon this, here is an easy way to page through all results. This same format also works for other API objects like Products as well.

orders = shopify.Order.find(since_id=0, status='any', limit=250)
for order in orders:
    # Do something with the order
while orders.has_next_page():
    orders = orders.next_page()
    for order in orders:
        # Do something with the remaining orders

Using since_id=0 will fetch ALL orders because order IDs are guaranteed to be greater than 0.

If you don't want to repeat the code that processes the order objects, you can wrap it all in an iterator like this:

def iter_all_orders(status='any', limit=250):
    orders = shopify.Order.find(since_id=0, status=status, limit=limit)
    for order in orders:
        yield order
    
    while orders.has_next_page():
        orders = orders.next_page()
        for order in orders:
            yield order

for order in iter_all_orders():
    # Do something with each order

If you are fetching a large number of orders or other objects (for offline analysis like I was), you will find that this is slow compared to your other options. The GraphQL API is faster than the REST API, but performing bulk operations with the GraphQL API was by far the most efficient.
