please help me out.
As said, you should click on the link [source] just at the right hand
side of the page, at the top. There is
numpy.cov(m, y=None, rowvar=True, bias=False, ddof=None, fweights=None,
aweights=None)
and just next to it there is the link. It takes you there:
https://github.com/numpy/numpy/blob/v1.19.0/numpy/lib/function_base.py#L2270-L2481
Which is the source code of the function.
Best regards,

Thanks

You can look it up yourself: Go to the docs
https://numpy.org/doc/stable/reference/generated/numpy.cov.html
At the right hand side, just right of the function signature, there is a
link [source]. Click there and it takes you to the implementation.
Apparently it is done in straightforward Python.

I think the np.cov is from the numpy module (imported/aliased as np?).
