Count rows and columns

Question

How would I go about defining a fuctions in counting the number of rows and columns in a list of lists? For example group1 would be 1 row with 6 columns.

group1  =   [['.',  'A',    'A',    '.',    '.',    '.']]



def num_rows(group):



def num_columns(group):

Just check the first index:

def num_rows(group):
    return len(group)

def num_columns(group):
    return len(group[0])

Take in mind this will raise an IndexError exception if there's no rows.
