Troubles with place_order.py

🐍 Full Python Script: place_order.py

I can not get this to function properly. This is where I keep having errors. I have inserted the key into the Beem wallet. I may need to unlock it but I'm not sure how, or do I get the code to do so while running the trade bot?... Any help is good help

Below is the complete code for placing buy/sell orders on Hive Engine using your Hive account and BEEM API
