[FIXED] sample from randomly generated numbers?

Issue

There is a program that needs to get 100 samples from 1000 randomly generated number distributed in [1, 500]. How can do I get a random sample from the output?

I wrote the following:

N = 1000
x = 1 + 500 * np.random.rand(N) 
sp_x = random.sample(x, 100)

I am getting an error:

TypeError: Population must be a sequence or set.  For dicts, use list(d).

Solution

From your code, the resulting x is a numpy array. To check type(x) output: numpy.ndarray

But the function random.sample(sequence, k) can only take in a sequence that is a list, tuple, string, or set. So your code could be:

import random
N=1000
x = 1+500*np.random.rand(N) 
x = list(x)
sp_x = random.sample(x,100)
print(len(sp_x))

output: 100
