Python 2.7 is end-of-life since January 2020 and not supported by python-control since version 0.9.1

Please use a more recent Python. It looks like you installed python-control into your Python 2.7 user site-lib with pip install control using the system wide pip. Make sure pip points to a Python 3 version or use pip3. Use python3 instead of python afterwards. (See also PEP 294)
