Generate a list of integer excluding -1, 1 and 0.

savecancel

In python, I made this code to pick numbers from a list of numbers, excluding -1, 0 and 1. I can't find the equivalent in sage.

def alea(n, max):
    complete_list = [i for i in range(-max, max+1, 1) if i != 0 and i != -1 and i != 1]
    list = random.sample(complete_list, n)
    return(list)

With Sage, I've done this :

sage: def alea(n, max):
....:     list = [randrange(-max, max+1) for i in range(n)]
....:     return list
....: 
sage: a = alea(5,10)
sage: a
[1, 3, 8, -9, 7]

and as you can see, 1 is in the list of course.

My goal will then be to take for example 4 random numbers a, b, c and d, to make a sum of fractions a/b+c/d, and to generate the answer automatically to make a series of exercises in a document written with latex/sagetex. That's why I need to exclude -1, 0 and 1.

Thanks in advance for your help .

edit :

under sage (jupyter) I have this error
