- Python: Random numbers into a list - Stack Overflow
The one random list generator in the random module not mentioned here is random choices: my_randoms = random choices(range(0, 100), k=10) It's like random sample but with replacement The sequence passed doesn't have to be a range; it doesn't even have to be numbers The following works just as well: my_randoms = random choices(['a','b'], k=10)

If you're only pulling a single item from a list though, choice is less clunky, as using sample would have the syntax random sample(some_list, 1)[0] instead of random choice(some_list) Unfortunately though, choice only works for a single output from sequences (such as lists or tuples)
- python - Create a list of random numbers - Stack Overflow
Assignment (but I wrote my own code): Asks the user for size, L_size, and creates a list, L, with L_size real numbers in it The numbers should be generated randomly (the random generator should be
- Generate n unique random numbers within a range [duplicate]
I know how to generate a random number within a range in Python random randint(numLow, numHigh) And I know I can put this in a loop to generate n amount of these numbers for x in range (0, n): listOfNumbers append(random randint(numLow, numHigh)) However, I need to make sure each number in that list is unique
- How do I create a list of random numbers without duplicates?
@wjandrea yeah I'm aware that Python 3 range produces a generator Back when I posted that comment if you tried sample = random sample(range(1000000000000000000), 10) you could watch the memory of the process grow as it tried to materialize the range before extracting a sample
- Create random list of integers in Python - Stack Overflow
It is not entirely clear what you want, but I would use numpy random randint: import numpy random as nprnd import timeit t1 = timeit Timer('[random randint(0, 1000) for r in xrange(10000)]', 'import random') # v1 ### Change v2 so that it picks numbers in (0, 10000) and thus runs t2 = timeit Timer('random sample(range(10000), 10000)', 'import random') # v2 t3 = timeit Timer('nprnd randint
- Generating a list of random numbers, summing to 1
For e g: lets say you want to generate 3 numbers, with min_thresh=0 2 We create a portion to fill by random numbers [1 - (0 2x3) = 0 4] We fill that portion and add 0 2 to all values, so we can get 0 6 filled too This is standard scaling and shifting used in random numbers generation theory
- python - Create a list of N random numbers with max and min value and . . .
I'm trying to create a list (call it: weights) of N random numbers between 0 005 and 0 045 with a total sum equal to 1 N can be any integer between 22 and 200 So the following restrictions: Number of numbers in weights = N; For every n in weights: 0 005 < n < 0 045; sum of all n's in weights = 1; The first restriction is easy I think
