How to create tuple with a loop in python

Question

I want to create this tuple:

a=(1,1,1),(2,2,2),(3,3,3),(4,4,4),(5,5,5),(6,6,6),(7,7,7),(8,8,8),(9,9,9)

I tried with this

a=1,1,         


        

Answer 1

itertools.repeat can also be used here:

>>> from itertools import repeat
>>> [tuple(repeat(i, 3)) for i in range(1, 10)]
[(1, 1, 1), (2, 2, 2), (3, 3, 3), (4, 4, 4), (5, 5, 5), (6, 6, 6), (7, 7, 7), (8, 8, 8), (9, 9, 9)]

If you want the final result to be in a tuple of tuples instead of a list of tuples, you can wrap tuple again:

>>> tuple(tuple(repeat(i, 3)) for i in range(1, 10))
((1, 1, 1), (2, 2, 2), (3, 3, 3), (4, 4, 4), (5, 5, 5), (6, 6, 6), (7, 7, 7), (8, 8, 8), (9, 9, 9))
