I want to convert tuple like

t = [(4,10),(9,7),(11,2),(2,2)]

into 2D array like:

a = [[4,10],[9,7],[11,2],[2,2]]

I tried

a = []
for i in t:  
    a.append(np.asarray(i))
print a

is there any easier way?

    a = map(list, t) Py2 , map changes in Py3 and you need a = list(map(list, t)) for Py3 Commented Jan 17, 2016 at 17:15
  • @AChampion As OP is using Python 2.7, I think there is no need to cast the map()result to a list. Commented Jan 17, 2016 at 17:17
  • Thanks, I was in the process of fixing - I work almost exclusively in 3 now so tend to forget these anachronisms. Commented Jan 17, 2016 at 17:18

Use a list comprehension as follows:

>>> t = [(4,10),(9,7),(11,2),(2,2)]
>>> [list(item) for item in t]
[[4, 10], [9, 7], [11, 2], [2, 2]]
