I was watching this video https://www.youtube.com/watch?v=yK2gaTztYqM&index=27&list=PLf0swTFhTI8pronNK7Gm-isKX7tdNb0Go
and practicing it on lab
I typed
ordersStatuses = orders.map(lambda order: order.split(",")[3])
then everything was good
then I typed
for orderStatus in ordersStatuses.collect(): print(orderStatus)
then the lab kinda stopped, I am attaching screenshot here. Kindly help.
