how to get source code of python print function?

Question

I am trying to get source code of python print using inspect but it is throwing error. Can someone please tell me how to get the source code of python2.7 print statement.

inspect.getsourcefile(print)

Answer 1

The print function is implemented in C language. That's why you can not reach its source code with the inspect module. The code is here: https://github.com/python/cpython/blob/2.7/Python/bltinmodule.c#L1580

• computergorl: Here's a link to the current source code if anyone's wondering: github.com/python/cpython/blob/3.8/Python/bltinmodule.c#L1821

Answer 2

There is an implementation of print() in C. The project has the closest generic implementation of print() I've even seen.

And the cpy project aims to implement all built-in methods of Python in C most minimally. It should be helpful.
