The built-ins in categories 3 and 4 are the specialized built-ins, which are often very useful but your need for them will vary based on your use for Python.

Not sure where you got that code, but anyhow the math module documentation doesn't point to the module's source code, it is implemented in C in https://hg.python.org/cpython/file/tip/Modules/mathmodule.c.

To do what you want all you need is to raise to the power of 0.5:

>>> 4**0.5
2.0

As for the second question, you'd need to find the balance between your natural curiosity and the desire to dig and learn, and the constraints of time and productivity. It is important to expand your knowledge, but not as an excuse for procrastination.
