No, this isn't so. And besides, the main function isn't even the first thing in your program to run. The standard library does some setting up first. For instance populating argc and argv.

There is definitely a main function in the CPython source code.

The code to parse and populate commandline arguments comes from the linker, and is part of the generated binary, not the standard library. Here's a much better explanation https://embeddedartistry.com/blog/2019/04/08/a-general-overv...
