Show DataFrame as table in iPython Notebook

How to Display DataFrames as Tables in iPython Notebook

Are you using iPython Notebook and struggling to display DataFrames as tables? Don't worry, you're not alone! Many users face this issue where trying to display multiple DataFrames leads to unexpected results. But fear not, we've got you covered with some easy solutions and tricks to ensure your DataFrames are displayed beautifully as tables.

The Problem: Collapsed Tables

Let's start by understanding the problem. When you use the following code in iPython Notebook:

df

You get a beautiful table with cells, neatly displayed. However, if you try to display multiple DataFrames one after another, like this:

df1
df2

You'll notice that the first beautiful table doesn't appear. Instead, you'll see the output of both DataFrames printed separately. Even if you use the "print" statement, like this:

print df1
print df2

The tables are printed in a different format that spills columns over and makes the output very tall, making it less readable and user-friendly.

The Solution: Pandas and Display Options

To force iPython Notebook to display DataFrames as beautiful tables, you can use the display() function from the IPython.display module. Here's how you can do it:

from IPython.display import display

display(df1)
display(df2)

Using display() ensures that each DataFrame is displayed as a separate table, just like how it appeared when you printed them one after another without using the print statement. This solves the problem of collapsed tables and makes it easier to analyze and compare multiple DataFrames.

Bonus Tips: Customizing the Display

If you want to customize the display of your DataFrames further, you can make use of the set_option() function from the pandas module. For example, you can adjust the maximum number of columns or rows to be displayed by using:

import pandas as pd

# Set the maximum number of columns to 10
pd.set_option('display.max_columns', 10)

# Set the maximum number of rows to 100
pd.set_option('display.max_rows', 100)

Feel free to experiment with different options to suit your specific needs and requirements.

Conclusion

Displaying DataFrames as tables in iPython Notebook shouldn't be a hassle. By using the display() function from the IPython.display module, you can easily solve the problem of collapsed tables and ensure that each DataFrame is displayed beautifully. Additionally, by utilizing the set_option() function from the pandas module, you can further customize the display according to your preferences.

Next time you're working with DataFrames in iPython Notebook, give these solutions a try and enjoy the clarity and simplicity of well-organized tables. Happy coding! 😄
