why code... alist = ['cat','dog','cow'] item in alist: print alist output ['cat', 'dog', 'cow'] ['cat', 'dog', 'cow'] ['cat', 'dog', 'cow'] while changing print alist item outputs: cat dog cow i understand when printing alist print list many times there elements in list guess don't understand why different. i grateful if explain difference me or point me in right direction. you have list - contains cat, dog, , cow. then say: each thing in list, print list. you have 3 things in list (cat, dog, , cow) list gets printed 3 times. when switch statement print item instead of print alist saying each thing in list print thing - each thing in list gets printed, ie cat, dog, cow.

i have graph (and raw data) shown below. the axis in graph in cm. want know area of deep blue area in graph (the answer should 20 sq.cm. or that). there way find it? if you're sure literally mean deepest shade of blue, corresponds minimum of data. can find minval = min(mydata(:)); . once have minimum value, select points equal value minvals = mydata == minval; . note collect elements equal deepest blue, in floating point sense. if didn't literally mean deepest shade of blue, might want consider selecting points within threshold of minimum value instead. count them total = sum(minvals(:)); . then multiply number of points value representing area of each point in cm2.
