Python: converting tuple into 2D array

Question

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?

Answer 1

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]]
