Why terminal on Mac OS X doesn't see python?

Question

Python

I wanted to disable python2.7 and enable python3.5. But I did it wrong, disabled python2.7 with this command

sudo ln -f /usr/bin/python2.6 /usr/local/bin/python

Now the terminal does not respond to commands such as:

python
which python

I know that some programs on Mac OS X work on python2.7.
I need to return the previous state of python so that it reacts to commands in the terminal because

python
which python

These files in /usr/bin are available, they have not been removed:

python-config
python2.6
python2.6-config
python2.7
python2.7-config
pythonw
pythonw2.6
pythonw2.7

Answer 1

ln -f removes the symbolic link
ln -s creates the symbolic link
you disabled 2.7 and 3.5 did not re-enable.

Answer 2

in fact, you just deleted a symbolic link to one of /usr/bin/python*
, you need to create it and life will get better
