"Could not find a version that satisfies the requirement itertools" while installing itertools

Question

I am getting an error while installing itertools on Windows 8.

C:\>pip install itertools
Collecting itertools
ERROR: Could not find a version that satisfies the requirement itertools (from versions: none)
ERROR: No matching distribution found for itertools

It should install the itertools package.

Answer 1

itertools is one of the modules included in the Python Standard Library, so it is not necessary to install: https://docs.python.org/3.8/library/itertools.html#module-itertools

Answer 2

You can already import from itertools directly.

For example, to use the chain module's from_iterable function which belongs in itertools, you can write it as:

from itertools import chain as ch

And then use it as:

ch.from_iterable()
