+### 4.4 Python tests
+
+You can run the python tests from the build or test directory:
+
+```bash
+$ cd <exiv2dir>/build (or cd <exiv2dir>/test)
+$ make python_tests  
+```
+
+If you wish to run in verbose mode:
+
+```bash
+$ cd <exiv2dir>/build   (or cd <exiv2dir>/test)
+$ make python_tests VERBOSE=1
+```
+
+The python tests are stored in the directory `tests` and you can run them all with the command:
+
+```bash
+$ cd <exiv2dir>/tests
+$ python3 runner.py
+```
+
+You can run them individually with the commands such as:
+
+```bash
+$ cd <exiv2dir>/tests
+$ python3 runner.py --verbose bugfixes/redmine/test_issue_841.py  # or $(find . -name "*841*.py")
+```
+
+You may wish to get a brief summary of failures with commands such as:
+
+```bash
+$ cd <exiv2dir>/build   ( or cd <exiv2dir>/test)
+$ make python_tests 2>&1 | grep FAIL
