Remove misc python programming recommendations

We want to keep the style guide as minimal as possible.  A separate
miscellaneous programming recommendations document might be added
in the future.

@@ -167,44 +167,3 @@ Use `f"...{var}"` when writing Python 3.6+ code, or `"...{0}".format(var)`
 anywhere. `"..." + var` may be used for simple cases, but beware of pitfalls
 such as easily missed whitespace, or `var` not being a string. Don't use the
 old `"...%s" % var`-notation.

-It seems a bit lost here. -->

-- Avoid large vertical separation of `if` and `else` keywords.
- ```python
- # NO:
- if bizbaz:
- frobnicate(flimflam)
- ...
- ...
- ...
-
- else:
- raise YamException("No bizbaz, no frobnicate!")
- ```
- Use the *"return early"* pattern, if the `else` clause would raise an
- exception or returns:
-
- ```python
- # YES:
- if not bizbaz:
- raise YamException("No bizbaz, no frobnicate!")
-
- frobnicate(flimflam)
- ...
- ...
- ...
-
- ```
- Returning early is generally useful to avoid excessive levels of nesting
- (aka. *"arrowhead anti-pattern"*).
-
- If returning early is not an option, and `if` and `else` are thus both
- needed, it is slightly preferable to keep the shorter clause first, so that
- the `else` isn't too far from the `if`.
