When I try to type "open" in the notebook it gets the color green and later on during the execution the code related to open gives an error message. I tried this in multiple notebooks and same result. The code that I provided in the notebook only serves the purpose that the 'open' statement is shown as green, and when it is green it can not be processed in any of the python code that I write. Therefore I cannot write any custom factors with the 'open' input.
Please help me in this issue.
