What happens when you instruct python to run your script?

Python first compiles your source code to byte code and sends it to python virtual machine (PVM). Byte code is the platform independent representation of your source code. PVM reads the byte code one by one and execute them.

Note:
Byte code is not machine understandable code, it is python specific representation.
