使用 Flask 对 Pandas 中的给定列数据执行算术运算

Question

To retrieve database values of the particular row back into the template (webpage) by doing some calculations. But I don't know how to get particular values from an SQL table and perform calculations.

So for this purpose, I tried Flask along with Pandas . I stored some data in MySQL tables and was able to retrieve its content back into a Flask template in table format:

geo = pd.read_sql_table('rsinputs', engine, columns=['province', 'county', 'depmin', 'inventory', 'geo', 'grades', 'asratio', 'dpbaux', 'deratingai203', 'deratingas', 'becol', 'bfcol', 'bgcol', 'bhcol', 'bicol'])

Yes, the output I got is DB tables, but now how do I perform calculations like some value from province + some value from the inventory?

Answer 1

Yeh, i solved it by myself..

bf12 = geo['bfcol'].iloc[2]

geob = bf12+bf12
