# How to check your Python version in Jupyter Notebook

The easiest way to check your Python version in Jupyter Notebook is to:

Import the python_version method from the platform module.
Call the python_version() method to print the Python version as a string.

Start Jupyter Notebook by issuing the jupyter-notebook command from your terminal.

Click on New and select Python 3 (ipykernel).

Now, import the python_version method from the platform module and call it.

Copied!
from platform import python_version print(python_version())

Once you import and call the method, click on the Run button or press Ctrl + Enter .

The screenshot shows that my Python version is 3.11.3.

The code sample imports the python_version method from the platform module.

Unlike the sys.version attribute, the string always contains the patch component (even if it’s 0 ).

If you have virtual environments that you are trying to switch to from within Jupyter Notebook:

Click on Kernel.
Hover over Change kernel.
Select your virtual environment.

If you encounter any issues when switching virtual environments, restart the kernel.

If you need to create a new virtual environment in Jupyter Notebook, follow the instructions in this article.

# Check your Python interpreter in Jupyter Notebook using the sys module

You can use the sys module if you need to check your Python interpreter in Jupyter Notebook.

Copied!
import sys print(sys.executable) # 👉️ /usr/bin/python3.11

The sys.executable attribute returns the absolute path of the executable binary of the Python interpreter.

If Python can’t determine the path to the interpreter, then sys.executable returns an empty string or a None value.

There is also a sys.version attribute that returns a string containing:

the version number of the Python interpreter
additional information about the build number and the compiler

Copied!
import sys print(sys.executable) # /usr/bin/python3.11 # 👇️ 3.11.3 (main, Apr 5 2023, 14:14:37) [GCC 11.3.0] print(sys.version) # 👇️ sys.version_info(major=3, minor=11, # micro=3, releaselevel='final', serial=0) print(sys.version_info)

The sys.version_info attribute returns a tuple that contains five components of the version number:

All components except for the release level are integers.

The release level component can be one of the following:

You can access specific tuple elements at an index.

Copied!
import sys # 👇️ sys.version_info(major=3, minor=11, # micro=3, releaselevel='final', serial=0) print(sys.version_info) print(sys.version_info[0]) # 3 print(sys.version_info[1]) # 11 print(sys.version_info[2]) # 3 print(sys.version_info[3]) # final

# Using the !python —version command to check your version

You can also use the !python —version command to check your Python version in Jupyter Notebook.

Copied!
!python --version # same as above !python -V

The !python -V command is an alias of the !python —version command.

Notice that the command is prefixed with an exclamation mark.

This is necessary when issuing the command in a Jupyter cell.

The exclamation mark ! is used to run a shell command in Jupyter.

You can use the !jupyter —version command if you need to check your Jupyter version.

You can also use the Help menu to check your Python version in Jupyter Notebook:

The version of the notebook server
The Python version that is run in Jupyter Notebook
Additional information about the current kernel

If you encounter issues when checking your version, try restarting the kernel.

Python check which python version jupyter notebook isusing

If you meant «packages»: Question 3: Even though you did not ask the question, «How do I set the Python version I want to use in Sublime text, VS Code or Jupyter Notebook?» , here’s some things you can try. Solution: You can locate Jupyter startup script and check what interpreter it uses: In my case it is /usr/bin/python3 , so it uses Python 3.

How can I know that which python my jupyter notebook is using and how can I change to use conda python?

You can locate Jupyter startup script and check what interpreter it uses:

user@pc:~$ which jupyter /home/user/.local/bin/jupyter user@pc:~$ cat /home/user/.local/bin/jupyter #!/usr/bin/python3 # -*- coding: utf-8 -*-

In my case it is /usr/bin/python3 , so it uses Python 3.

You can uninstall current version and install Jupyter for another python installation by executing

pip3 uninstall jupyter /path/to/another/python -m pip install jupyter

Which Python — Versions, locations and uses

Question 1: How can I know which one is being used in Sublime text, Vs Code or Jupyter notebook?

Run the following code in any of those applications to get the Python version that it is using:

import sys print(sys.version)

Question 2: How can I know which packets (sic) I have installed in each python version?

import sys import pkg_resources print(sys.version) packages = pkg_resources.working_set packages_list = sorted(["%s==%s" % (i.key, i.version) for i in packages]) for p in packages_list: print(p)

Question 3: Even though you did not ask the question, «How do I set the Python version I want to use in Sublime text, VS Code or Jupyter Notebook?» , here’s some things you can try.

In Sublime Text:
- Select Tools -> Build System -> New Build System .
- Enter the following text:
```
< "cmd": [, "-u", "$file"], "file_regex": "^[ ]*File \"(. *?)\", line (2*)", "selector": "source.python", > 
```
How to check python version in jupyter notebook Code Example, from platform import python_version print(python_version())

How do I match version of python version between jupyter notebook and terminal? 3.6.5 to 3.7

First you need to install Jupyter for Python 3.7. As you can see when you run python3 in the console it comes up with Python 3.7 so that’s the command you want to be using.

Installing Jupyter
Here is the documentation for reference. According to the documentation you simply just run:
```
python3 -m pip --upgrade pip python3 -m pip install jupyter 
```
Running Jupyter on Python 3.7
python3 -m pip install jupyter
Will run Jupyter, but specifically on python3 , which is bound to Python 3.7 for you.

*This is how I remember doing it but I haven’t tested it right now so if something has changed this may not work.

Jupiter notebook doesn’t find libraries from the virtual env

I would suggest to click on «Kernel» in the jupyter notebook bar (in the top). Next go to «Change Kernel» then select the venv you created

Edit: ok I tried it myself

after you activate your venv make sure to ..

install jupyter within the venv:
```
ipython kernel install --name "my-venv" --user 
```
(or however you want to name it) -> this will add your virtualenvironment as kernel for jupyter

when inside the notebook click on «New» in top right corner, then choose the name you gave the kernel before («my-venv») -> et vilà
