How to print absolute value from list of negative valued tuples?

Question

I have a list that have tuples with negative values say like this

vect=[(-x*3,-y*2) for x in [2,3,4] for y in [1,5,6]]

and i want to print the list with its absolute values like

[(6, 2), (6, 10), (6, 12), (9, 2), (9, 10), (9, 12), (12, 2), (12, 10), (12, 12)]

but i tried to get an output but got an error that

TypeError: bad operand type for abs(): 'tuple'

So I need a help or suggestions regarding this problem.

It's good you've posted the error, but you haven't posted the code that produces the error... — Tom Dalton, May 07 '18 at 12:38
`[(abs(x), abs(y)) for x, y in vect]` or `[tuple(abs(x) for x in tup) for tup in vect]` — Aran-Fey, May 07 '18 at 12:40

Using map

Ex:

vect=[(-x*3,-y*2) for x in [2,3,4] for y in [1,5,6]]
print([map(abs, i) for i in vect])     #Python3 --> print([list(map(abs, i)) for i in vect])

Output:

[[6, 2], [6, 10], [6, 12], [9, 2], [9, 10], [9, 12], [12, 2], [12, 10], [12, 12]]

[(abs(i[0]), abs(i[1])) for i in vect]

# [(6, 2), (6, 10), (6, 12), (9, 2), (9, 10), (9, 12), (12, 2), (12, 10), (12, 12)]
