DOC: rm np import

I had thought we didn't do this by convention (neither for numpy, which is in the line below, contradicting that convention), because it would be everywhere.

Is that the case? I don't have a particularly strong view either way, though we could decide on the convention now.

that's what I was thinking, too: technically we don't need any imports of numpy, pandas or xarray:

xarray/conftest.py

Lines 26 to 41 in 351b0aa

	@pytest.fixture(autouse=True)
	def add_standard_imports(doctest_namespace, tmpdir):
	import numpy as np
	import pandas as pd
	import xarray as xr
	doctest_namespace["np"] = np
	doctest_namespace["pd"] = pd
	doctest_namespace["xr"] = xr
	# always seed numpy.random to make the examples deterministic
	np.random.seed(0)
	# always switch to the temporary directory, so files get written there
	tmpdir.chdir()

so I would lean towards removing all of those. That said, it would probably be good to have some obvious part of the docs (api.rst?) explain that all examples assume these imports.

Thanks for the FYI. Guessed it would go one way or the other.

I guess that's good to go, then. thanks @raybellwaves
