import pkg resources packages    dist project name for dist in pkg resources working set  try     for count  item in enumerate packages         print item  pkg resources get distribution item  version  except      pass here  The indentations might not be perfect  The reason I am using a Try- Except block is that few library names will throw errors because of parsing the library names to process the versions  even though packages variable will contain all the libraries install in your environment

The python function returning just the package version in a machine-readable format   from importlib metadata import version  version  numpy     Prior to python 3 8   pip install importlib-metadata  from importlib metadata import version version  numpy     The bash equivalent  here also invoked from python  would be much more complex  but more robust - see caution below    import subprocess def get installed ver pkg name       bash str  pip freeze   grep -w  s    awk -F        print  2     tr -d   n     pkg name      return subprocess check output bash str  shell True  decode      Sample usage     pkg name  xgboost    pkg name  Flask    pkg name  Flask-Caching  pkg name  scikit-learn   print get installed ver pkg name    gt  gt  gt  0 22   Note that in both cases pkg name parameter should contain package name in the format as returned by pip freeze and not as used during import  e g  scikit-learn not sklearn or Flask-Caching  not flask caching   Note that while invoking pip freeze in bash version may seem inefficient  only this method proves to be sufficiently robust to package naming peculiarities and inconsistencies  e g  underscores vs dashes  small vs large caps  and abbreviations such as sklearn vs scikit-learn    Caution  in complex environments both variants can return surprise version numbers  inconsistent with what you can actually get during import    One such problem arises when there are other versions of the package hidden in a user site-packages subfolder  As an illustration of the perils of using version   here s a situation I encountered     pip freeze   grep lightgbm lightgbm  2 3 1  and    python -c  import lightgbm  print lightgbm   version     2 3 1  vs     python -c  from importlib metadata import version  print version   lightgbm      2 2 3  until you delete the subfolder with the old version  here 2 2 3  from the user folder  only one would normally be preserved by  pip  - the one installed as last with the  --user  switch      ls  home jovyan  local lib python3 7 site-packages lightgbm   home jovyan  local lib python3 7 site-packages lightgbm-2 2 3 dist-info  home jovyan  local lib python3 7 site-packages lightgbm-2 3 1 dist-info   Another problem is having some conda-installed packages in the same environment  If they share dependencies with your pip-installed packages  and versions of these dependencies differ  you may get downgrades of your pip-installed dependencies   To illustrate  the latest version of numpy available in PyPI on 04-01-2020 was 1 18 0  while at the same time Anaconda s conda-forge channel had only 1 17 3 version on numpy as their latest  So when you installed a basemap package with conda  as second   your previously pip-installed numpy would get downgraded by conda to 1 17 3  and version 1 18 0 would become unavailable to the import function  In this case version   would be right  and pip freeze conda list wrong     python -c  from importlib metadata import version  print version   numpy      1 17 3    python -c  import numpy  print numpy   version     1 17 3    pip freeze   grep numpy numpy  1 18 0    conda list   grep numpy numpy                     1 18 0                   pypi 0    pypi

and with --outdated as an extra argument  you will get the Current and Latest versions of the packages you are using      pip list --outdated distribute  Current  0 6 34 Latest  0 7 3  django-bootstrap3  Current  1 1 0 Latest  4 3 0  Django  Current  1 5 4 Latest  1 6 4  Jinja2  Current  2 6 Latest  2 8    So combining with AdamKG  s answer      pip list --outdated   grep Jinja2 Jinja2  Current  2 6 Latest  2 8    Check pip-tools too   https   github com nvie pip-tools
