Question

This question maybe asked earlier (atleast topic wise) , but still I couldn’t find a solution for my specific problem. Basically, I need a multidimensional array in python. Such that:

I will be able to access contents in list by :

contenets[no_of_record][record]. 

So I have a file like :

101, Mrs. Jones' Math Class, 10100000001, Jones, Barbara, , , , 10100000011, Gutierrez, Kimberly, 2
101, Mrs. Jones' Math Class, 10100000001, Jones, Barbara, , , , 10100000013, Mercado, Toby, 1
101, Mrs. Jones' Math Class, 10100000001, Jones, Barbara, , , , 10100000014, Garcia, Lizzie, 1
101, Mrs. Jones' Math Class, 10100000001, Jones, Barbara, , , , 10100000015, Cruz, Alex, 1

Now I have to maintain a multi dimensional array where no_of_record points to row number and the record will be the column number.

I want something similar to this:

contents=[][]

for lines in source_file:
                contents[no_of_records][]=lines.rstrip().split(',')
                print contents[no_of_records]
                no_of_records+=1

I am sure the snippet above is syntactically wrong, I am just trying to give an idea of what im searching for. Thanks for your help.

You can also do it with dicts, which may be better, if you want to use something other than numbers for the indices.

contents = []
tmp_rcd = {'classnum': 101, 'classname': "Mrs. Jones' Math Class", ...}
contents.append.tmp.rcd
...
print contents[i]['classname']
