For example: df= gi ptt_loc 0 384444683 593 1 384444684 594 2 384444686 596 To, df= index1 gi ptt_loc 0 0 384444683 593 1 1 384444684 594 2 2 384444686 596 回答1: either: df['index1'] = df.index or, .reset_index : df.reset_index(level=0, inplace=True) so, if you have a multi-index frame with 3 levels of index, like: >>> df val tick tag obs 2016-02-26 C 2 0.0139 2016-02-27 A 2 0.5577 2016-02-28 C 6 0.0303 and you want to convert the

Users provide their data in the form 0xARGB, and I need to convert it to 0xAARRGGBB . And yes, there could be millions, because each could be a pixel. 1000x1000 pixels equals to one million.

Here is how I do it: let array = Array(results) // la fin 回答2: If you absolutely must convert your Results to Array , keep in mind there's a performance and memory overhead, since Results is lazy. But you can do it in one line, as results.map { $0 } in swift 2.0 (or map(results)

In perl, there is an easy (and fast) way to do this: my @array = qw( 1 2 3 ); my %hash; @hash{@array} = undef; This generates a hash that looks like: { 1 => undef, 2 => undef, 3 => undef, } The best I've come up with in Ruby is: array = [1, 2, 3] hash = Hash[array.map {|x| [x, nil]}] which gives: {1=>nil, 2=>nil, 3=>nil} Is there a better Ruby way? EDIT 1 No, Array.include? is not a good idea. Its slow . It does a query in O(n) instead of O(1). My example

It would be a better idea not to store structured data in a string if you can avoid it, though. 回答2: Within Django's templates you can use the date Template Filter: {{ value|date:"h:i:s a" }} # '18:30:00' would appear as 6:30:00 p.m. {{ value|date:"g:i:s a" }} # '18:30:00' would appear as 06:30:00 p.m.
