Print(timeit. Print(timeit.timeit("sample_bits(1024)", setup="from _main_ import sample_bits", number=10000)) Rbytes = np.random.randint(0, 255, dtype=np.uint8, size=n_bytes) You do not need to enter any values, just click the. Here is some more demo-approach using numpy (which surprisingly does not have a method dedicated for this job exactly): import numpy as np Our 10 between 1 and 100 random number generator allows you to quickly pick up random numbers online. If you need many bits or can pre-calculate bit-arrays for later consumption, numpy's methods might shine. If you need single bits (one per call), you already did your benchmark and other answers provide additional info. Although method 1 is shortest (main advantege) for now I would choose method 3: def positive_or_negative():Īny better (faster or shorter) method to randomly generate -1 or 1 in Python? Any reason why would you choose method 1 over method 3 or vice versa? Part 1: Enter List Items Enter your items in the field below, each on a separate line. The randomness comes from atmospheric noise, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs. Also both method 1 (since Python 3.6 I think?) and 3 give the possibility to introduce uneven distributions. List Randomizer This form allows you to arrange the items of a list in random order. Nearly 200 different animals Random Things Stuff, things, and 1000s common everyday objects pulled together at random for list of. Also filter by part of speech Random Animals Generated a random animal species: A goat, armadillo, orangutan, porpoise, cheetah. My bet was on method 1 to be the fastest as it is also shortest. Generate a random list of words from 2500+ of the most common English words. Timeit.timeit(stmt = s, setup = "import random") Random Numbers Combination Generator Number Generator 1-10 Number Generator 1-100 Number Generator 4-digit Number Generator 6-digit Number List Randomizer Popular Random Number Generators. For example, to generate 12 random numbers between 1 and 100, you can use RANDARRAY like this: RANDARRAY (12,1,1,100,TRUE) The rows argument sets how many numbers are returned, columns is 1, start is 1, end is 100, and integer is set to TRUE. If you want 1 to 100, you could use this (thanks to martineau for pointing out my convoluted solution): myrandoms random. S = "my_number = (-1)**random.randrange(2)" The RANDARRAY function makes it easy to generate a list of random integers. You could use random.sample to generate the list with one call: import random myrandoms random.sample(range(100), 10) That generates numbers in the (inclusive) range from 0 to 99. # if I understand correctly random.random() should never return exactly 1 What would be the best way to generate 1 or -1 in Python? Assuming even distribution I know I could use: import random I wanted to generate 1 or -1 in Python as a step to randomizing between non-negative and non-positive numbers or to randomly changing sign of an already existing integer.
