Is Python main at top or bottom?

This is done to ensure all necessary functions and classes are defined before they are called.Should main be at the top or bottom in Python?
Most important functions should be at the top, so people can know what the program does, without going through every implementation details.

Musk started with a book on the BASIC programming language, a popular language in the 1960s, which many computers still used in the 1980s. The book offered a six-month program to learn to code, but Musk raced through the entire program in three days. It wasn't long before Musk programmed his first video game.Does NASA use C++ or Python?
