Welcome to DataFrames

A DataFrame is how Pandas represents a table. You can access columns, rows and individual cells.

Suppose you constructed a DataFrame by 

import pandas as pd

df = pd.DataFrame({'name': ['Jeff', 'Esha', 'Jia'], 
                   'age': [30, 56, 8]})

Giving you the DataFrame

name age
1 Jeff 30
2 Esha 56
3 Jia 8

Now, you want to select a value out of the table, say the first name:

first_name = df.name[0]

Define a variable expected_name with the value first_name will have.
