I need to read my file, grab the first part of a string (up to the first number), make a new file with that as the name. Then put all the other lines matching that String into the matching file. Example:

ABC1

ABC2

ABC3

CBA1

CBA2

CBA3

So it should read the lines, get the “ABC” from line one, make a file name “ABC” and then put all the ABC rows in the new file. then grab “CBA” make a new file and put all the CBA rows in the CBA File.

Please help!! I am so lost and confused.

I am learning python and have no idea how to start.
