I have this fixed width data file (data.txt) which I would like to reformat. Data is something like this, with hundreds of rows and columns, every row finishes to END:
PRJ01001 4 00100END PRJ01002 3 00110END PRJ01003 3 00120END PRJ01004 2 00130END PRJ01005 1 00140END PRJ01006 1 00150END PRJ01007 3 00160END I would like to pick only some columns to a new file and put them to a certain places (to match previous data) - definition file (def.csv) could be something like this: VARIABLE FIELDSTARTS FIELD SIZE NEW PLACE IN NEW DATA FILE ProjID ; 1 ; 5 ; 1 CaseID ; 6 ; 3 ; 10 UselessV ; 10 ; 1 ; Zipcode ; 12 ; 5 ; 15 So the new datafile should look like this: PRJ01 001 00100END PRJ01 002 00110END PRJ01 003 00120END PRJ01 004 00130END PRJ01 005 00140END PRJ01 006 00150END PRJ01 007 00160END If the datafile was as narrow as in this demofile, I would simply use notepad to fix this, but there are more than 100 variables I should pick and replace... I'm missing the logic here - how it should be done? -- http://mail.python.org/mailman/listinfo/python-list
