Column Operations

pandas provides vectorized operations by specifying the individual Series in the DataFrame. New columns can be assigned in the same way. The :meth:DataFrame.drop method drops a column from the DataFrame.

tips["total_bill"] = tips["total_bill"] - 2 tips["new_bill"] = tips["total_bill"] / 2 tips

tips = tips.drop("new_bill", axis=1)
