I've already installed python3 on my computer. when I started a new Jupyter notebook I selected python 3 but now on the notebook, it is saying it isn't there
when I run this: print(python_version())
i get this error:
NameError Traceback (most recent call last) in ----> 1 print(python_version())
NameError: name 'python_version' is not defined
import sys; print(sys.version)
