Learn Pandas - The Most Popular and Useful Python Library for Data Science

Pandas is one of the most popular Python libraries in data science. In fact, Pandas is among those elite libraries that draw instant recognition from programmers of all backgrounds, from developers to data scientists.

According to a recent survey by StackOverflow, Pandas is the 4th most used library/framework in the world. That is quite an achievement!

Pandas is the first library we import when we fire up our Jupyter notebooks (‘import pandas as pd’ is indelibly etched in our minds!). It is a super flexible tool that enables us to perform data analysis and data manipulation on Pandas dataframes in double-quick time.

As a beginner in data science and especially Python, you’ll have a lot of questions about Pandas

Common Questions Beginners ask about Pandas

  • What is Pandas?

    Pandas is a fast, powerful, flexible and easy to use open source data analysis and manipulation library built in Python.

    Pandas is THE most popular Python library in data science and the 4th most popular library in the world (according to StackOverflow’s global survey). The open source nature of Pandas isone of the primary reasons for its popularity and adoption rate in the community.

    Here’s a golden nugget about Pandas from Wikipedia: The name ‘Pandas’ is derived from the term "panel data", an econometrics term for data sets that include observations over multiple time periods for the same individuals.

  • How can I install Pandas in Python?

    The easiest way to install Pandas is to install it as part of the Anaconda distribution. Anaconda is free and easy to install (it’s the installer we use for setting up Python as well).

    We highly recommend doing this instead of trying to install Pandas from scratch (it will be a slightly difficult process if you’re not familiar with Python or programming in general).

  • Where is Pandas used in data science?

    Pandas is primarily used in data science and machine learning in the form of dataframes. As we’ve mentioned above, Pandas enables us to perform all sorts of data analysis and manipulation tasks in Python, including importing different data files like CSV, Excel, JSON, etc.

    Most data science projects use Pandas to perform aggregating functions like GroupBy, merge and join dataframes, impute missing values in Python, among other things.

    In short, Pandas is an essential part of a data science project!

  • What is a Pandas dataframe?

    In Pandas, a dataframe is a data structure used to store and manipulate tabular data. The tabular data has it’s columns, column names and rows - we can easily perform operations on large dataframes using Pandas functions.

    A Pandas dataframe is also the standard structure used to store the data from common formats of data like CSV file, Excel sheets and others.

  • How difficult is it to learn Pandas?

    It’s actually quite straightforward! Even though Pandas has a ton of features and functions, you can easily pick those up with a bit of practice.

    And that’s exactly how we’ve designed the course! You’ll learn all the different Pandas functions in Python and then work on various exercises after each lesson to solidify what you’ve learned.

  • Do I need to know Python to learn Pandas?

    It would definitely help to have basic Python programming knowledge if you want to maximize your Pandas experience. The ability to merge or join Pandas dataframes, manipulating data and so on will require a bit of Python programming.

    If you’re completely new to Python, we recommend taking our free Python for Data Science course.

  • What kind of data analysis can I perform using Pandas?

    You can perform all kinds of data analysis and data manipulation using Pandas. We cover the key points in this course but here is a list for your reference:
    ● Reading and writing data from different file formats like CSV, Excel, JSON, etc.
    ● Data alignment
    ● Handling missing data
    ● Reshaping data and building pivot tables using Pandas
    ● Label-based slicing, fancy indexing, and subsetting of large datasets
    ● Column insertion and deletion using Pandas dataframes
    ● Group by allowing split-apply-combine operations on datasets
    ● Dataset merging and joining
    ● Filtering dataframes, and so on

  • Will Pandas help me become a better data scientist?

    Short answer - yes. Which data science project won’t appreciate someone who can perform quick analysis and data manipulation? This is a key part of any data science project and mastering Pandas will go a long way towards making you a better and more efficient data scientist.

    Additionally, this will also help you in your interview rounds when you’re asked to analyze certain data (Pandas is your best friend!).

  • What kind of data formats can I import using Pandas?

    The beauty about Pandas is the remarkable number of files we can read into Python. Here’s a quick list:
    1. Comma-separated values (CSV)
    2. XLSX
    3. ZIP
    4. Plain Text (txt)
    5. JSON
