I created a border which works but I want to draw a box in the border here is my code import curses screen = curses.initscr() try: screen.border(0) box1 = curses.newwin(20, 20, 5, 5) box1.box() screen.getch() finally: curses.endwin() any advice? furas From curses docs : When you call a method to display or erase text, the effect doesn’t immediately show up on the display. ... Accordingly, curses requires that you explicitly tell it to redraw windows, using the refresh() method of window objects. ... You need screen.refresh()

I'm looking for a way to draw a cone at a specific location in a 3D surf plot. Would it also be possible to have the cone 50% transparent? Right now I'm drawing a basic 3d environment using the surf function. I'm trying to use the function plot3 to draw a cone with specific dimensions at a specific location. The following code creates a cone by pinching a cylinder between zero and one with t=[0;1] . The alpha(...) function fan then be used to set the transparency. To reposition a cylinder you must add a value to the x,y, or z or perform a rotation (beyond the scope of this answer). t = [0;1];

i have an nested tuple like this: mostfrequent = (('16.37.97.17', '178.237.19.228', '55177', '443', '6', '1', '46'), ('16.37.97.17', '178.237.17.97', '44492', '443', '6', '1', '46'), ('16.37.97.29', '178.237.17.61', '56326', '443', '6', '1', '46'), ('16.37.97.222', '104.131.44.62', '60179', '80', '6', '2', '620'), ('16.37.93.196', '16.37.157.74', '2049', '691', '6', '1', '100')) I want to draw every element of every subtuple with networkx declared via nodelist: nx.draw_networkx_nodes(G, pos, nodelist=flattened_list_nodes, node_size=1600, node_color='blue', alpha=0.6) For that i flattened the
