Renaming file based on file content at a particular location

The input task is as follows:

• There are multiple files generated from DIA Equipment with filename as random number.
• The following parameters in the input file are to be extracted:
  • LotID
  • StepID
  • ResultsID
  • WaferID
  • DeviceID

The output is as follows:

• The random named files will be renamed w.r.t nomenclature as <lot_id>_<step_id>_<wafer_id>. E.g: F19310002.F1_POLY_WF01
• The modified & renamed files will be moved from src to dest directory i.e. <device_id>/<step_id>/<lot_id>/YEDI1/
• Also, the following parameters of the respective file is changed:
  • LotID
  • ResultsID

The pseudo code is as follows:

1. Walk in directory of the input files i.e. source directory.
2. Open the files (in read mode) with (*.001) extension (if available) in the given directory. E.g. "./data"
3. Extract the respective parameters information - lineno, values,
4. Modify the params - output_filename, new_deviceid, new_resultsid
5. Write it back inside the file
6. Create the folder(s) with deviceid, lotid, stepid, if doesn't exist.
7. rename & move the files from src to des location. Use this func: os.rename(src, des)
   • Use try & except exception handling in order to check if the modified file already exists.

• Case-1: simply put the data files into "./coding/data"
  • Here, the files should be moved from src to des
• Case-2: put the data files into "./coding/data", but don't delete the new folder, subfolders & the set of moved files
  • Here, run repeatedly to see if there is any subfolder being created inside the "device" folder e.g. 'F19010001.F1POLY', 'F19010001.F1POLYPOLY'
• Case-3: put the data files into "./coding/data", but delete the moved files from dest directory.
  • This moves the modified & renamed file into the destination directory.
