You can use a while statement until you get a number out of your excluded numbers excludedNumbers = [1,2,3,4] randomNumber = random.randomint(1,100) while randomNumber in excludedNumbers: randomNumber = random.randomint(1,100) After the while you have a number outside the excluded nu

Re: random number including 1 - i.e. [0,1]

bability of getting 0 or n as any other value. If you want to perform a fair roll of a 6-sided die, you would start with int(random.random() * 6). This gives a random number in the range [0,5], with each value of the same probability. How to get our die roll that goes from 1 to 6? Add 1. Thus:

True random number generator

truerandom.py is a Python module that generates true random numbers obtained from www.random.org. Use with the form: mylist=truerandom.getnum(min,max,amount) mylist will be a list containing the true random numbers. If for some reason the numbers cannot be generated, the list will contain -1. Y

What random number generator is used for Numeric and SciPy?

Python bases its random number generators on the Mersenne Twister.   Do Numeric and SciPy also base their random number generators on the Mersenne Twister? If not, what do they use?-- http://mail.python.org/mailman/listinfo/python-list
