I was studying the difference between lists and tuples (in Python). An obvious one is that tuples are immutable (the values cannot be changed after initial assignment), while lists are mutable. A sentence in the article got me: Only immutable elements can be used as dictionary keys, and hence only tuples and not lists can be us...

Hi, My program uses PyOpenGL (so it's Python) with psyco. I have around 21,000 line segments which I need to render in each frame of my render (unless the user zooms in, in which case line segments are culled and not sent to the card at all). This is currently taking around 1.5 seconds each frame to complete. That's just not good enoug...
I have a big csv file which lists connections between nodes in a graph. example: 0001,95784 0001,98743 0002,00082 0002,00091 So this means that node id 0001 is connected to node 95784 and 98743 and so on. I need to read this into a sparse matrix in numpy. How can i do this? I am new to python so tutorials on this would also help. ...

Hi, I need to send a file to another server using oauth and webpy. For now I'll ignore the oauth part as sending the file itself is already a challenge.
