Accessing elements in a multidimensional list in python

list is a data type in Python which consists of a group of elements.The elements are declared in a pair of square brackets.For example to declare a simple list you can use the following:

nums=[1,2,3,4]

you can even mix elements of different types in a list as:

listObj=[1,5,"a","b"]

The items in the list can be other lists.Instead of a string or numeric value we can declare a list as list item.This is called multidimensional list.

A multi dimensional list is declared as:

multiList=[['a','b','c'],['a','b','c']]

Accessing elements in a multidimensional list

after declaring a multi dimensional list you need to access the elements of a multi dimensional list.In the following example we are iterating all the elements of a multidimensional list

 listObj=[[1,2,3],[1,2,3]]
rows=len(listObj)
cols=len(listObj[0])
for x in range(rows):
 for y in range(cols):
   print("item=%s"%(listObj[x][y]))
