Even at the interactive prompt some of the dangers (mostly the potential for name collisions) of from xxx import * are still present. -Peter -- http://mail.python.org/mailman/listinfo/python-list

Beginner question: Logs?
Hey everyone! I'm a math student working on a short script involving logs. I have a function on my scientific calculator, and was wondering if there was a similar funtion in python. For example: (log65536)/(log4)= 8 I've searched around a bit and haven't been able to find anything. Thanks! -Christian -- http://mail.python.org/mailman/listinfo/python-list

Hey thanks... Still getting an error message though. Here's what i'm doing: -- import math log10(15625) -- -It says that log10 is not defined, but it is since the module is imported, right? -- http://mail.python.org/mailman/listinfo/python-list
