Display all dataframe lines in python

Sometimes when you want to see all lines in ipython, either in IDE or in notebook, it wont show you because of in-build options. Here are those options, in case you want to change that :

import pandas as pd
pd.set_option('display.max_rows', 500)
pd.set_option('display.max_columns', 500)
pd.set_option('display.width', 1000)
