pandas DataFrames are two-dimensional data structures, which you can think of as spreadsheets in Excel. DataFrames allow us to easily import the .csv files using a simple command. For example, the following sample code allows us to import the raw_data.csv file:

import pandas as pddf = pd.read_csv("raw_data.csv")

Once the data is imported as a DataFrame, we can easily perform data preprocessing on it. Let's work through it using the Iris flower dataset. The Iris flower dataset is a commonly used dataset that contains data on the measurements (sepal length and width, petal length and width) of several classes of flowers. First, let's import the dataset as provided for free by University of California Irvine (UCI). Notice that ...
