Format integer column of Dataframe in Python pandas

In this Tutorial we will learn how to format integer column of Dataframe in Python pandas with an example. We will learn

  • Round off a column values of dataframe to two decimal places
  • Format the column value of dataframe with commas
  • Format the column value of dataframe with dollar
  • Format the column value of dataframe with scientific notation

Let’s see each with an example. First lest create a dataframe.

 

Create Dataframe:

# create dataframe

import pandas as pd
d = {'Quarters' : ['Quarter1','Quarter2','Quarter3','Quarter4'],
     'Revenue':[23400344.567,54363744.678,56789117.456,4132454.987]}
df=pd.DataFrame(d)
print df

So the resultant dataframe will be
