Fixing command not found python in Mac after installing Python3(python3 will be available)

Python python

You have two main options to make the python command work, and I recommend Option 1 as the cleanest modern solution.

Option 1: Use `python3` (Recommended)

The most straightforward and modern way is to always use python3 in your command line.

To run a script:
```
python3 your_script.py
```
To enter the interpreter:
```
python3
```
This is the current best practice for Python development.

Option 2: Create a Shell Alias

If you really prefer typing python, you can tell your shell (Zsh) to treat the command python as python3.

Open your Zsh configuration file (.zshrc):
```
nano ~/.zshrc
```
Add the following line to the end of the file:

alias python='python3'
Save and close the file (press Control-X, then Y, then Enter).
Reload your shell configuration to apply the change:
```
source ~/.zshrc
```

Now, when you type python, your system will actually execute python3.
