How to change datatype of a column/series in pandas (Python)

[@KraivKris]

Hi. Thank you for the tutorial, but i have a question ¿How can you save permanently that change?

Hi,
The change takes place immediately. In order to revert back, you need to change the datatype again. Thanks

@@TechMoney33 once I save the dtype changes in a new csv, when I read that new csv doesnt preserve the changes.

@@kraivprob4529 For that one you can change the datatype while you are importing dataset into python. You have the option to specify datatypes for columns with read csv. Thanks
