Match two data sets based on item values

[klllmmm]

I have two data frames, which i want to combine usinga left join or similar.
PV number wise subtotal of the amount column of the dataframe (Pmt) has to be match with the second table (BankWithdrawal).
If such sub total matches then join that row of second table with the relevant first table rows. Resultant table with the other two tables attached.

Get the sub totals in PVNo wise from Pmt dataframe

subtotal=pmt[["PVNo.","Amount"]].groupby('PVNo.').sum()

Great if someone can help me to achive the resultant table.
