Hello all - brand new to Quantopian but with some basic Python experience. Beginner question incoming - How do you call functions in the notebook? I have just tried executing a simple function and call (attached) and receive an error message.
I had a quick look around but could find no obvious answer. I have already developed a script which calls a few custom functions in Python, and want to hook it up to Quantopian research environment for data / testing.
All the best
Blake
