October 12, 2026 - The entire Python directory is cleaned of temporary files that may have resulted from a previous compilation. An instrumented version of the interpreter is built, using suitable compiler flags for each flavor. Note that this is just an intermediary step.

Debate: Enforcing Python source encoding as UTF-8
However, I recently was told that forcing the source encoding to UTF-8 can be bad for cross-platform compatibility, since Windows doesn't default to UTF-8. First of all, as far as source files go, Windows doesn't default to anything, programs do. Notepad in Windows-7 defaults to UTF-8, if your code editor is worse than Notepad then you probably should get another code editor. Maybe the person who told you that was thinking about encoding of stuff like file names in syscalls? I'm not sure what's supposed to be the alternative approach then. If you use ASCII encoding for source files and manually encode Unicode characters with backslash escapes in bytestrings you still has to decide how to encode them, in UTF-8 or UCS-2 that Windows expects. And the correct way is, of course, to just use unicode literals instead. Also, you can't "not enforce" the source encoding, if you don't specify UTF-8 then it's 7-bit ASCII. Which is good, because I can't imagine how an unspecified source encoding can be good for cross-platform compatibility -- if someone runs your script on Windows and Python there somehow decided to use UTF-16, they get garbage printed out?

July 31, 2014CPython internals: A ten-hour codewalk through the Python interpreter source code - YouTube
Here are nine lectures walking through the internals of CPython, the canonical Python interpreter implemented in C. They were from a dynamic programming languages course that I taught in Fall 2014 at the University of Rochester. The format isn't ideal, but I haven't seen this level of detail about CPython presented online, so I wanted to share these videos.

May 8, 2021 -
Which programming language was used to build python interpreter from scratch?I want to make a workable mini python like interpreter from scratch , not as hobby but as big project.
I want to see a minimalistic python interpreter (but same python workable) not as big today is, this would help me graps more .
Thank you for helping me

One exception to the first line rule is when the source code starts with a UNIX “shebang” line. In this case, the encoding declaration should be added as the second line of the file. For example: ... On Unix, the Python 3.x interpreter is by default not installed with the executable named python, so that it does not conflict with a simultaneously installed Python 2.x executable.

Each code object contains a set of instructions to be executed—that's the bytecode—plus other information that the interpreter will need. Bytecode is an intermediate representation of Python code: it expresses the source code that you wrote in a way the interpreter can understand.

November 27, 2019 - The Interpreter’s Core: ceval.c At the heart of Python’s execution lies a massive switch statement in ceval.c. It cycles through each opcode, handles stack operations, and dispatches calls to underlying C functions. Although this file is large and heavy with macros, it’s the best place to see exactly “how Python runs your code.”
