Code:

import sys
from sage.all import *
def rand_LS(n):
    m=LatinSquare(n)
    m[0,0]=randint(0,n-1)
    for i in range(0,n-1):
        for j in range(0,n-1):
            while true:
                m[i,j]=randint(0,n-1)
                if (m.is_completable()):
                    break
    return m

range(0,n-1) goes from 0 to n-2, you should use range(0,n) or range(n).

But keep the randint(0, n-1) as it is! It is one of the confusing Python conventions.

Indeed, and you can replace randint(0, n-1) with randrange(n).
