Almost certainly because you are not running exactly the same code each
time.

Not quite. It depends on what arguments you give it.
py> a = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
py> sum(a, [])
[1, 2, 3, 4, 5, 6, 7, 8, 9]

The code doesn't define 'np', so this line should produce an error.
The code you linked contains this import:
import numpy as np
However you didn't show it here, so I wonder if you poste
Hi,
I run below code, which is downloaded from link:
http://stackoverflow.com/questions/15513792/expectation-maximization-coin-toss-examples?rq=1
# represent the experiments
head_counts = np.array([5,9,8,4,7])
tail_counts = 10-head_counts
experiments = zip(head_counts,tail_counts)
11 matches
