how to generate 10000 random no. in a range 30,40

I have issue i want to generate 10000 random float no's in a given range, I cannot use random module because it will always go out of my range

x=random.randrange(30.000000,40.000000,10000)

i tried this

and i'm exepcting 10,000 random float no. b/w them

Solution

  • You could use random.uniform like:

    import random
x = [random.uniform(30.0, 40.0) for i in range(10000)]

    Alternatively, you could use numpy like:

    import numpy as np
x = np.random.uniform(30.0, 40.0, 10000)

    NB: The second option would give you an ndarray, which is normally fine, but if your program requires you to have a list instead, you can just do this instead:

    import numpy as np
x = np.random.uniform(30.0, 40.0, 10000).tolist()
