How to convert data type: Object to Float/Decimal

Question

Hello. I tried float(), to_numeric(), convert_object, astype() but still can't make operations from column A and Column B of a Dataframe. How can I convert such datatypes? Or are there any ways to fetch the column then convert it to float? The data in the columns are both amounts with 2 decimals places. I'm 1 month new to Python. What I want to do with the columns is to get their difference.
Thanks in advance! Happy Learning.

Answer 1

In general, this should work
data['A'] = data['A'].astype(float)
