How can I be sure I'm working in the correct Python version with pyenv?

Question

I setup my pyenv by followign the steps on this page.

pyenv versions gives me this:

$ pyenv versions
  system
  2.7.8
  3.4.3
  3.5.0
  3.6.3
  3.6.4
* 3.7.2 (set by /Users/me/PycharmProjects/ConfigureDsNet/.python-version)

I assume that the current active Python version in pyenv is 3.7.2.

If I now do python -V I see this:

Python 3.4.3

How can I be certain which version I'm working with?

As Neeraj Kumar pointed out, adding eval "$(pyenv init -)" in the ~/.bash_profile resolved the issue.
