Notnull() explanation

Course Name: Python for Trading: Basic, Section No: 8, Unit No: 16, Unit type: Notebook

Hi team,

In the explanation for notnull(), isn't it supposed to be read as "...it will return 'False' if the data point is a 'NaN' value (boldfaced below)? I think notnull() returns 'True' if the data is not "NaN" value.

Hello Yeong,



It's true what you're saying. We'll get that fixed right away.



Thank you very much for making us notice that.
