#How to get contingency table
import pandas as pd

#Read the csv data file
data = pd.read_csv('train.csv')

#Getting 'Embarked' feature values without null value
embarked = data[pd.notnull(data['Embarked'])]['Embarked']

#Getting 'Survival' feature values correponding to 'Embarked' 
survived = data[pd.notnull(data['Embarked'])]['Survived']

#Creating contingency table using pd.crosstab() function
con_table = pd.crosstab(embarked, survived)
