Re: Need help initializing a list or tuple.

Strange behaviour... a = [[None] * 256] * 256 for i in range(0,256): for j in range(0,256): a[i][j] = i**2 a = sum(a, []) print a[0] print a[65535] Prints: 65025 65025 -- http://mail.python.org/mailman/listinfo/python-list

Re: Argument Precedence (possible bug?)

Hello, Steven D'Aprano, Terry Jan Reedy! I would really like to extend my thanks to you guys. I hope I've got it right this time! def posKeyArgs(a, b=2, c=3): print a, b, c #posKeyArgs(b=20) # too few positional arguments. a needs an arg. #posKeyArgs(10, c=30, 20) # pos_args cannot follow

Fetch info from website and write to txt file.

I want to make a program that get info from a website and prints it out in a txt file. I made this: import urllib f = urllib.urlopen("http://www.imdb.com/title/tt0407304/";) s = f.read() k = open("test.txt","w") k.write(s) k.close() f.close() That saves all the html code into the test.txt file.
