Is there any way to programmatically determine if the array you are parsing is a regular array or a two dimensional array?
For example, how would you distinguish:
array1 = ["This", "Is", "A", "Sample", "Array", "."]
from
array2 = [["This", "Is"], ["A", "Sample"], ["Array", "."]]

A really really ghetto way of doing it could be:

Code

if str(array2).count("[") > 1 and str(array2).count("],") > 1:
    print "Multi dimensional"
else:
      print "One dimensional"

You can use type() to check the type of something. If you check the first item in the list, you can check if it's a list. It the first element of a list is a list, then it is two dimensional. Like this:

Code

ls = [[1,2],[3,4]]
if type(ls[0]) is list:
    print ("Is 2D")
else:
    print ("Not 2D")

That or you could use isinstance:

PHP Code


<?php 
a = [[1,2,3],[4,5,6]]
print isinstance(a[0],list) 


And if you wanted to check if any of the items are a list:

PHP Code


<?php 
a = [[1,2,3],[4,5,6]]
print any(map(lambda x:isinstance(x,list),a))
