Text field decleration

[Madavian]

I have to process text files with fixed length fields.

Does Python provide for a way to define the fields?
I need something like the following.

text file = 'aaabccccccccddddeff...'

converted to :-

field1 = 'aaa'
field2 = 'b'
field3 = 'cccccccc'
etc....

I am using - field1 = file[0:3] # for first field

I am sure that there must be a better way.

Thanks

See the struct module.

http://docs.python.org/lib/module-struct.html

The unpack() method should do the trick.
