getting index of element in list (python) -

-
didn't understand why getting index of elements in list works differnt in next examples: list = [1, 1, 1, 4] print list.index(list[3]) returns expected 3 index fourth element in list but list = [1, 1, 1, 1] print list.index(list[3]) unexpectedly returns 0. what difference? it's python 3.3 list.index(x) returns index of first match. in first case first match @ index 3 i.e., 4 @ index 3, while in second case first match @ index 0 i.e, 1 @ index 0. 1 @ indices 1,2 , 3.

does write method of serialport write bytes told to? have code send data via serial port. serialport port = new serialport( "com1", 9600, parity.none, 8, stopbits.one); // open port communications port.open(); // write bytes byte[] bytes = encoding.ascii.getbytes("hello world pc"); port.write(bytes, 0, bytes.length); // close port port.close(); if send string "hello" device connected pc via serial port receives well. if send string "hello world pc" receives first 16 bytes instead of 19. there way can verify in code bytes sent? or problem of hardware connected via serial port? yes, .write synchronous data send before returns. anyway, 30 second timeout more enough, event if wouldn't.

optimization - Python, combinations, permutations without repeat -

-
python. have 2 lists, same length. idea build paired data (for regression analysis). figured out loops , this. a=(1,3,5,7) #first list b=(2,4,6,10) #second list w=zip(a,b) #paired values both lists i=0 j=0 each in w: x= w[i] in xrange(i,len(w)-1): i+=1 print x, w[i] j+=1 i=j the output expected - first pair second, third.. on, second pair third, fourth.. , on (skipping combination between second pair , first pair, because kinda same combination of first , second pairs...) (1, 2) (3, 4) (1, 2) (5, 6) (1, 2) (7, 10) (3, 4) (5, 6) (3, 4) (7, 10) (5, 6) (7, 10) [..] , on expecting. the question - there other, shorter, optimized ways how rewrite code, maybe using itertools? yes: itertools.combinations print list(itertools.combinations(w, 2)) you mention in question - i'm not sure why wouldn't in docs before asking on stackoverflow.

i'm performing drawing operations on canvas. best way calculate cursor position relative canvase top left corner is, in opinion, usage of .getboundingclientrect() : htmlcanvaselement.prototype.relativecoords = function(event) { var x,y; //this current screen rectangle of canvas var rect = this.getboundingclientrect(); //recalculate mouse offsets relative offsets x = event.clientx - rect.x; y = event.clienty - rect.y; //debug console.log("x(",x,") = event.clientx(",event.clientx,") - rect.x(",rect.x,")"); //return array return [x,y]; } i see nothing wrong code , works in firefox. test it. in google chrome however, debug line prints this: x( nan ) = event.clientx( 166 ) - rect.x( undefined ) what doing wrong? is not according specifications? edit: seems code follows w3c: from specs: getboundingclientrect() the getboundingclientrect() method, when invoked, must return result of following algo
