Best place to find sample data

[Nicholas Cannon]

Hey I need some sample data to test out and do stuff with. Also I am having strange errors with idle when i load a .txt file read it and then print it, idle crashes well kind of freezes. Not sure what is wrong here. Also I am having troubles with Numpy and its loadtxt function:

ValueError: cannot set an array element with a sequence

So all i need is a good site to download some data from and maybe some fixes for these problems.
