I have a data-frame:
df1 = pd.DataFrame({'ShipTo': ["", "", "", ""], 'Item_Description':["SYD_QANTAS ", "SYD_QANTAS", "PVG_SHANGHAI", "HKG_JARDINE"]})
I'd like to create a string merge in the column ShipTo "B" + first 3 characters from the column "Item_Description" so the result would be:
How can I do that?
