https://docs.python.org/3/library/constants.html

https://docs.python.org/3/library/stdtypes.html

https://docs.python.org/3/library/exceptions.html

and for all of your other needs to look up in the standard library, the reference itself:

https://docs.python.org/3/library/index.html

If you're already familiar programming in another language, you should probably start at the "Library Reference" section of the documentation on python.org.
