What are “named tuples” in Python?
... __slots__ = ()
def __init__(self, *args):
for slot, arg in zip(self.__slots__, args):
setattr(self, slot, arg)
def __repr__(self):
return type(self).__name__ + repr(tuple(self))
# more direct __iter__ than Sequence's

Most simple but complete CMake example
...ocal/share/ and something equivalent on windows. I wanted to have a simple zip/tar.gz that you can extract anywhere and run. Therefore resources are loaded relative to the executable.
the basic rule to understand cmake commands is the following syntax:

What's the difference between equal?, eql?, ===, and ==?
...uals(o)
ops = [:==, :===, :eql?, :equal?]
Hash[ops.map(&:to_s).zip(ops.map {|s| send(s, o) })]
end
end
"a".all_equals "a" # => {"=="=>true, "==="=>true, "eql?"=>true, "equal?"=>false}
== — generic "equality"
At the Object level, == returns true only if obj and othe...
Why is the order in dictionaries and sets arbitrary?
...ctionary in between. That means that d.items() is essentially identical to zip(d.keys(), d.values()). If any items are added to the dictionary however, all bets are off. The order could change completely (if the hash table needed to be resized), though most of the time you'd just find the new item t...
