A very basic one but important part here to know is most of the command will have the same syntax to get the version details

python3 --version

Simplest Hello (without world)

Again a basic once, but this tells us that we can run a small python snippet just via the cli, without writing/creating a python file. a lot of other programming languages (basically their executables) also gives the same functionality

python -c "print('Hello')"

Get MD5 Hash

A quick way to get MD5 hash of a string

python3 -c "import hashlib; print(hashlib.md5(b'Ashish').hexdigest())"

same goes for sha512

python3 -c "import hashlib; print(hashlib.sha512(b'Ashish').hexdigest())"
