Doing the ‘hands-on’ for Data Engineer Basics - “Learn to Use the Cognite Python SDK “ Course."
I have done the following:
- Make a dataframe from reading from a csv file:
One of the columns in the csv file is ‘region’. The 5 different values in the region column are
When the above code is run, the following appears on the screen:
Q1. Does this mean pandas has interpreted the region “None” as “nan”?
If so that would explain why the following code throws “ValueError: Out of range float values are not JSON compliant. Make sure your data does not contain NaN(s) or +/- Inf!”

I would value your guidance as I have not worked with pandas() much at all.
Thank you,
Doug
