I am thinking Python may be what I need to use, but I am in the early stages of getting to know Python.  Can you point me to a really good, intuitive resource for getting up to speed with data. Something that would help with the following.

The txt file has several data elements and is 300 characters per line. I am only interested in the first two fields. The first data element is 19 characters. The second data element is 6 characters. I want to rearrange the data by moving the 6 characters data in front of the 19 characters data and then write the 25 character data to a new file.

Open the two files, using the 'with' statement. Using a for loop,
 iterate over the input file. For each line, use substring
 operators to fetch each field. Then write second + first.  Maybe
 6 lines.

If you can get most of this, show it to us, and tell us where
 you're stuck.
