You can also use special library functions to create arrays. To learn more, see our tips on writing great answers. btw, you can test boundary values by mocking random.Random to provide special values (it is enough to override .random, .getrandbits). I'm struggling to think of a case where this potential inability to return 1.0 in this case would have practical importance, given the extreme unlikelihood of returning that value even if it was possible to return it. This gives a number between 0.0 and 1.0, though you could easily set up a way to get around this. The syntax of this function is: random.randint(a,b) This returns a number N in the inclusive range [a,b], meaning a <= N <= b, where the endpoints are included in the range. To use Numpy in our code we need to import following module i.e. Why round the number at all? Using function random.uniform () To generate a random number between 0 and 1, there are several solutions for example using the random module with uniform (): >>> import random >>> x = random.uniform (0,1) >>> x 0.24773029475050623. The general randomness can be checked by existing tests (as a black box). Contribute your code (and comments) through Disqus. Failing tests and solutions that use os.urandom, ssl.RAND_bytes, etc could be checked by hand. The random() method in random module generates a float number between 0 and 1. Running the above code gives us the following result − 0.2112200 Generating Number in a Range. nextafter will produce the platform specific next representable floating pointing number towards a direction.

The probability density function of the normal distribution, first derived by De Moivre and 200 years later by both Gauss and Laplace independently , is often called the bell curve because of its characteristic shape (see the example below). Book that I read long ago. OK, so putting the craziness of your requirements aside: The fact that the lower bound for your random floats is higher than 0 gives you a disturbingly elegant way to use random.random, which guarantees return values in the interval [0.0, 1.0): Simply keep calling random.random, throwing away any values less than 0.1, except 0.0. The chance of getting exactly 1.0 is virtually 0 anyway...
