python - adding value limitations on list comprehension -


i trying find clean way of grabbing difference between values of 2 int tuples. tuples have limitations though represent rgb colors. have far:

tupleone = (255, 0, 255)  # magenta tupletwo = (255, 0, 0)  # red tuple([tupleone[x] - tupletwo[x] x in range(3)])  # makes blue

the problem have here bounds checking since each color value must 0-255. i'm going if larger number subtracted smaller, return 0 given index. have been using test single index:

value = -10 max(0, min(color, 255))  # value = 0

is can cleanly list comprehensions? or there better approach?

sure, combine you've got there:

tuple(max(0, min(tupleone[x] - tupletwo[x], 255)) x in range(3))

c# - DetailsView in ASP.Net - How to add another column on the side/add a control in each row? -

i have detailsview control on page used edit various fields of record, works in respect. i looking way add 1 column (and if works, why not more) right, absolutely read-only, show same fields of record comparison purposes. i aware there no obvious way such thing out of box detailsview . have looked other controls (transposed gridview , recommended formview , listview ), nothing satisfies. have special data binding setup using detailsview , can't out of without losing features. anyone on how "hack in" additional columns (for display only) on detailsview ? the solution have now, use second detailsview , visible set false in aspx. in code, make sure databind hidden detailsview hosts data third column first, initial detailsview named itemdetails . and in item created event, pass third column html rendering of hidden controls (in last code block) : protected void itemdetails_itemcreated(object sender, eventargs e) { if (dataite
