Changing an int datatype column to a float

To do this, we first check the datatypes of columns from our real dataset:

data.dtypes

The following is the output:

We assign the change back to the original column as follows:

data['Zhvi'] = data.Zhvi.astype(float) data.dtypes

In the following screenshot, we can see that the change has been made—the datatype of our column has been changed from int64 to float64:
