Hey, it's because python is written in C, so when you have code in C, your going from C to machine code and it's compiled at the beginning. Python is written in C, so your going from python to c and there's something about the compilation which isn't at the beginning but dynamic. Which means with c you going back and forth in 2 levels and in python 4 levels. All of which will add on time. With say a for loop day it's going to increase the steps by *2 but because of the added time of compilation and wait compile down one level, the speed decrease is significantly more.
No, "C to machine code" is just plain wrong. C is not interpreted. C is compiled, meaning there is no "go back and forth". If you write a programming language, let us say a compiled one, using C or using other language, and with an addition rule that the compiler can optimizes it, then the speed would be the same as C. Take a look at Rust, the language itself is using OCaml (at first, which is made using C).
Nowadays, C is compiled first to Assembly. There are some compilers that translate, assembling, C directly to machine code, TCC for example.
Python does not go to C. Who compiles Python code into C in terms of normal Python? Python use the opcode itself to optimizes itself. Take a look at the "dis" module in Python.

Sorry your right if your going one way. I was thinking of the classic nested for loop.
For i in xxx
For b in xxx
Should have added that in. In my head that was the classic example. Back and forth.
