I would like to get an array of integers in a certain range. But every number must occur once. Is there a possibility to do this as a simple one liner or simple command ?

Till now I only found

np.random.choice(10,10)

np.random.randint(1,10,9)

But both of these functions do not give back a vector where every number only occurs once.

Hint: I know that Iam not allowed to ask for more numbers than there is compared to the range.

Use `replace=False` in it as the optional arg. – Divakar Dec 23 '16 at 12:56
Thank you, this only worked with the choice command, do you know why ? – Kev1n91 Dec 23 '16 at 12:57
Because `np.random.randint` isn't meant for such a task. – Divakar Dec 23 '16 at 12:58
