Any reason why would you choose method 1 over method 3 or vice versa? Return : Array of defined shape, filled with random values. use numpy to generate many uint8's in one step, (there might be something better using internal functions without the randint-API), uniformity follows from randint's uniformity guarantees, not caring about different result-types of these functions, not caring about -1 vs. 0 (might be important in your use-case), (not even optimal compared to much more low-level approaches; MT used internally can be used as a bit-source, which does not need fp-math, like many other PRNGs!). This only returns values between 0.0 and 1.0 inclusive. x = random.rand () print(x) Try it Yourself ». Can I bring a single shot of live ammunition onto the plane from US to UK as a souvenir?
