Mark has already mentioned these:

  https://docs.python.org/3/py-modindex.html
  https://docs.python.org/3/genindex.html

I use the index a lot, especially if I have a (probable) method name.

There is also a search here:

  https://docs.python.org/3/

which has some utility. Note you need to wait for it to load the results.

I just tried searching for "pipe". Admittedly "subprocess.PIPE" is the very 
last thing listed, but still, it is there.

It is like a for loop, but you know that by now.
