Run the following command to check the path to your Python 3 installation:

$ which python3

This will show the full path of your Python 3 binary. On most systems, it should be /usr/bin/python3 or /opt/homebrew/bin/python3

cat ~/.zshrc

add line if not available : alias python=/correct-path-to-python3

example : alias python=/usr/bin/python3

source ~/.zshrc or restart terminal

python --version
