Which version of Python do I have installed?

  • 772

I'm trying to write a simple Python script using Geany. This IDE will automatically compile the code I write but I'm not sure which version of Python it is using. If I enter python --version in the command line I get:

Python 2.7.3

but if I enter python3 I get:

Python 3.2.3 (default, Oct 19 2012, 19:53:16) 
[GCC 4.7.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>>

Does Ubuntu come with both versions? If so, which one is Geany using to compile?

python

    Ubuntu comes with both versions, yes. The python command will always point to a Python 2.x version, and python3 will always point to the default Python 3.x version. The python command will never point to Python 3.x.

    I'm not sure what Geany uses exactly, but I would suspect it uses Python 2.x (and thus probably puts #!/usr/bin/python (or should put if it uses /usr/bin/env python instead), in the scripts it generates.

  2. Try running import sys;print(sys.version_info) from inside geany.

  3. You can use: 

    import sys
print sys.version

    To find out what version of python you are running.

    Of course due to changes in python 3 print is now a function so this won't work for version 3. In that case you would use: 

    import sys
print(sys.version)
