Have you ever tried to do math with a pandas Series that you thought was numeric, but it turned out that your numbers were stored as strings? @Suraj-Thorat said in Pandas Dataframe issue (int object has no attribute to_pydatetime): datetime open high low close volume 0 2019-09-03 15.50 15.50 14.30 14.45 681 1 2019-09-04 14.20 15.45 14.10 14.90 5120 And you have an index which is made up of int values. It is now possible to create a pandas column containing NaNs as dtype int, since it is now officially added on pandas 0.24.0. pandas 0.24.x release notes Quote: "Pandas has gained the ability to hold integer dtypes with missing values Convert a pandas column of int to timestamp datatype. pandas.
