The eval() function can also be used to evaluate the sum of rows with the specified columns. At first, let us create a DataFrame with Product records −dataFrame = pd.DataFrame({"Product": ["SmartTV", "ChromeCast", "Speaker", "Earphone"], "Opening_Stock": [300, 700, 1200, 1500], "Closing_Stock": [200, 500, 1000, 900]})Finding sum using eval(). The resultant column with the sum is also mentioned in the eval(). The expression displays the sum formulae assigned to the resultant column −dataFrame = dataFrame.eval('Result_Sum = Opening_Stock + Closing_Stock')ExampleFollowing is the complete code −import pandas as pd dataFrame = pd.DataFrame({"Product": ["SmartTV", "ChromeCast", "Speaker", "Earphone"], "Opening_Stock": [300, 700, 1200, 1500], "Closing_Stock": [200, ...
