Printing 1 to 1000 without loop or conditionals
... @Joseph - The constructor one shouldn't be affected by what order the individual objects are initiated, but it is a good question.

Comparing two dictionaries and checking how many (key, value) pairs are equal
... good idea, because the items in a dictionary are not supposed to have any order. You might be comparing [('a',1),('b',1)] with [('b',1), ('a',1)] (same dictionaries, different order).
For example, see this:
>>> x = dict(a=2, b=2,c=3, d=4)
>>> x
{'a': 2, 'c': 3, 'b': 2, 'd': 4}

Calling constructor from other constructor in same class
...
The order of constructor evaluation must also be taken into consideration when chaining constructors:
To borrow from Gishu's answer, a bit (to keep code somewhat similar):
public Test(bool a, int b, string c)
: this(a, b)

Delete directories recursively in Java
... .forEach(File::delete);
We use a comparator for reversed order, otherwise File::delete won't be able to delete possibly non-empty directory. So, if you want to keep directories and only delete files just remove the comparator in sorted() or remove sorting completely and add files f...
How to retrieve a single file from a specific revision in Git?
...pposed to git show, which allows you to save it under a different name, in order for you to get and see both (the current version and the old version). It is unclear from the question if the OP wants to replace its current version by an old one.

Should one use < or
... @Lie, this only applies if you need to process the items in forward order. With most operations in these kind of loops you can apply them to the items in the loop in any order you like. For example if you are searching for a value it does not matter if you start at the end of the list and wor...
Python nonlocal statement
...rstensen you could pass the function as an arg that's the beauty of higher order functions. Also in functional programming this is called composition, python is not a pure FP language but you can certainly play with a features (generators, higher order functions are some examples)

redis-py : What's the difference between StrictRedis() and Redis()?
... to provide backwards compatibility with older versions of redis-py:
LREM: Order of 'num' and 'value' arguments reversed such that 'num' can provide a default value of zero.
ZADD: Redis specifies the 'score' argument before 'value'. These were swapped accidentally when being implemented and not disc...
Copy the entire contents of a directory in C#
... letter each. I haven’t tried this. But just to illustrate the point: in order to make this code overflow on a typical computer, the directories would have to be nested a few thousand times. This is simply not a realistic scenario.
