How to find dimension of a nested tuple?

Question

I have a tuple that looks like this

  array=(1,2,3,4)
  lenM = numpy.shape(array)
  print lenM
  (4,)

  if not lenM[1]:
       "Code"

Now how do I automate the my code to find if the tuple is one dimensional or two dimensional?

Answer 1

You can use numpy.ndim for this:

In [4]: np.ndim((1,2,3,4))
Out[4]: 1
In [5]: np.ndim(((1,2),(3,4)))
Out[5]: 2

Answer 2

array=(1,2,3,4)
lenM = numpy.shape(array)
print lenM
(4,)

if len(lenM) == 1:
    "1 dimensional code"
elif len(lenM) == 2:
    "2 dimensional code"

len(lenM) will tell you if there is more than one dimension in array. If len(lenM) is 1, there's only one dimension. if array has more than one dimension, lenM will have more than one element.
