How to Check the Pandas Version in Your Script?

What is the Pandas Library?

The pandas library provides data structures and functionality to represent and manipulate labelled and tabular data.

Think of it as like an advanced spreadsheet program in your code with functionality including—but not limited to:

• creating spreadsheets,
• accessing individual rows by name,
• calculating basic statistics over rows and columns, and
• summing over cells that fulfill a certain condition.

How to Check Your Pandas Version in Your Script?

To check the pandas version running in your script, run two commands in your shell:

1. Import the library with import pandas as pd, and
2. Run and print the attribute pd.__version__ to check the pandas version running in your script.

Here’s the code and the output version on my computer:

import pandas as pd
print(pd.__version__)

The output in my Python script is:

1.0.1

How to Check Your Pandas Version with Pip? [Terminal, Shell, CMD]

To check your pandas version with pip in your Windows command line, Powershell, macOS terminal, or Linux shell, run pip show pandas. The second line of the output provides your pandas version.

$ pip show pandas
Name: pandas

How to Find the Dependency Versions for Your Given Pandas Version?

Pandas is a complicated library that depends on many external libraries (dependencies) itself.

To check the versions assumed by your current pandas version, run pd.show_versions() that returns a string representation with one dependency version per line.

• Import the library with import pandas as pd, and
• Run and print the function pd.show_versions() to check the version of the Pandas running in your script.

Here’s the code:

import pandas as pd
print(pd.show_versions())

And the output:
