suffix

I have the following source: int main() { 000J; } With gcc 4.8.4 it compiles without errors. I know there are suffixes like L or U, but I didn't find anything about J. So what does it do? I get a warning: Imaginary constants are a GNU extension The J suffix is a GNU extension, which causes the literal to be of a _Complex type. More info here: https://gcc.gnu.org/onlinedocs/gcc/Complex.html As zenith mentioned, this is a GNU extension for writing imaginary literals. I really want to comment on the rationale of using j for this purpose as imallett is wondering but I don't have enough reputation

I currently have a number of inputs like this: <input type="number" id="milliseconds"> This input field is used to represent a value in milliseconds. I do however have multiple number inputs which take a value in dB or percentages. <input type="number" id="decibel"> <input type="number" id="percentages"> What I would like to do is add a type suffix to the input field to let users know what kind of value the input represents. Something like this: (This image is edited to show what result I want to have,I hid the up and down arrows from the input type as well). I have tried to Google this but I

I have a list, a : a = ['a','b','c'] and need to duplicate some values with the suffix _ind added this way (order is important): ['a', 'a_ind', 'b', 'b_ind', 'c', 'c_ind'] I tried: b = [[x, x + '_ind'] for x in a] c = [item for sublist in b for item in sublist] print (c) ['a', 'a_ind', 'b', 'b_ind', 'c', 'c_ind'] I think my solution is a bit over-complicated. Is there some better, more pythonic solution? MSeifert You could make it a generator: def mygen(lst): for item in lst: yield item yield item + '_ind' >>> a = ['a','b','c'] >>> list(mygen(a)) ['a', 'a_ind', 'b', 'b_ind', 'c', 'c_ind'] You
