The quickest way to check the Python version is to run this command in the command line:
|
1 |
python --version |
Another, and quicker way (note the capital v):
|
1 |
python -V |
Both commands will work on all popular systems: Windows, Linux, and Mac.
More information
You can add another capital v, if you want more information, like the Python version, release date.
It will also display whether you use the 32-bit or 64-bit versions.
|
1 |
python -VV |
Python versions
There are two major Python versions: Python 2 and Python 3 that are not fully compatible.
If both versions are installed on the machine you can check for Python 2 using this command:
|
1 |
python --version |
or
|
1 |
python2 --version |
If you want to check python3 version, use this command:
|
1 |
python3 --version |
Check Python version inside the code
To check the version of Python interpreter inside the script you have to import the sys module first, and then display the Python version.
|
1 2 |
import sys print(sys.version) |
The print function will display this result:
|
1 |
3.7.2 (tags/v3.7.2:9a3ffc0492, Dec 23 2018, 23:09:28) [MSC v.1916 64 bit (AMD64)] |
You can also display the system version info:
|
1 |
print(sys.version_info) |
Result:
|
1 |
sys.version_info(major=3, minor=7, micro=2, releaselevel='final', serial=0) |
