This recipe helps you create a dataframe in python


Recipe Objective

While working with dataset, many a times we face a need of creating multidimensional array for storing data. In python, we can easily do it using by using the concept of dataframe.

So this recipe is a short example on how to create a dataframe in python. Let's get started.

Step 1 - Import the library

import pandas as pd

Let's pause and look at these imports. Pandas is generally used for data manipulation and analysis.

Step 2 - Setup the Data

grade_distribution = {'Student': ['Ram','Rohan','Shyam','Mohan'], 'Grade': ['A','C','B','Ex'] }

Let us create a simple dataset and store it in the form of dictionary.

Step 3 - Converting Dataset to Dataframe

Now we simply use pandas library imported earlier to covert the dataset to Dataframe

df = pd.DataFrame(grade_distribution, columns = ['Student','Grade'])

Step 4 - Printing Dataframe

Simply use print function to print the previously created dataframe.


Step 5 - Lets look at our dataset now

Once we run the above code snippet, we will see:
