Python on server showing wrong version?

Question

ubuntu

Hello, I installed python 3.5
the python3.5 command gives version 3.5
the python3 command gives version 3.4 I set up the
Flask application
I put an virtual environment inside the project

virtualenv -p python3.5 envname
source envname/bin/activate I
put the
pip install flask there,
but when I'm already on I print the version of python sys.version on the site, he writes 3.4
This sys.executable outputs this "/usr/bin/python3"
I understand that my project does not use a virtual environment?
How can I get him to start using it?
here is the contents of the envname folder is everything ok here?

Write the full path in virtualenv to the version of Python you need:
virtualenv --python=/bin/usr/python3.5 envname
