Styling multi-line conditions in 'if' statements? [closed]
...' and \
cond3 == 'val3' and cond4 == 'val4':
do_something
This at least gives you some differentiation.
Or even:
if cond1 == 'val1' and cond2 == 'val2' and \
cond3 == 'val3' and \
cond4 == 'val4':
do_something
I think I prefer:

Best exception for an invalid generic type argument
...emselves, then
InvalidOperationException should be
used.
There is at least one leap of faith in there, that method parameters recommendations are also to be applied to generic parameters, but there isn't anything better in the SystemException hierachy imho.

Failed to serialize the response in Web API with Json
...
There is no need to add the json serialiser (at least in my case) but removing the Xml formatting was needed. I guess the xml serialiser can't serialise anonymous types and by removing it the result is serialised as json. If my guess is correct one would be able to get dat...

Is there a “do … until” in Python? [duplicate]
...op-and-a-half construct guarantees that do_something() will be executed at least once, even if condition() is true at the beginning of the loop. Your while not condition(): do_something() construct will never execute do_something() if condition() evaluates to true at the beginning.

Compile time string hashing

At least by my reading of §7.1.5/3 and §5.19, the following might be legitimate:

Convert numpy array to tuple
...for a condition that is almost as common as the non-exceptional state. At least in c++, flow control by exceptions is usually frowned upon. Would it be better to test if type(a)==numpy.ndarray?
