The first step is to make sure that we have included all of the necessary Python libraries for all of the tasks that will be performed. This includes matplotlib for graphs, datetime
to manage various dates and time in the data, a few methods from NumPy, and random number capabilities from the random library:
In [1]: # necessary imports for the workbook import pandas as pd import pandas.io.data import numpy as np import datetime import matplotlib.pyplot as plt # Set some pandas options pd.set_option('display.notebook_repr_html', False) pd.set_option('display.max_columns', 6) pd.set_option('display.max_rows', 10) pd.set_option('display.width', 78) pd.set_option('precision', 4) # do all our graphics inline %matplotlib inline
