How do I add the contents of an iterable to a set?
...You can add elements of a list to a set like this:

>>> foo
set([0, 1, 2, 3])

set([0, 1, 2, 3, 4, 5])

The above will still not stop a user from manually entering a value outside of the specified range. Instead he will be displayed a popup telling him ...
Converting string to byte array in C#
... This will fail for characters that fall into the surrogate pair range.. GetBytes will have a byte array that misses one normal char per surrogate pair off the end. The GetString will have empty chars at the end. The only way it would work is if microsoft's default were UTF32, or if char...

Generate a random date between two other dates
... the later, multiply your random number (assuming it is distributed in the range [0, 1]) with that difference, and add again to the earlier one. Convert the timestamp back to date string and you have a random time in that range.
Python example (output is almost in the format you specified, other t...

More elegant way of declaring multiple variables at the same time

@Zac to correctly do so use a, b, c = ([] for i in range(3)). source. For consistency, you could also use a variant of that for this answer, i.e., a,b,c,d,e,g,h,i,j = (True for i in range(9)) f=(False i in range(1)).
