Quote:What does this part of the code below? Could you provide some explanation behind the lines of code as comments?
for example, filename = Path('/media/stubens/DataDrive-3XT/projs/T-Z/T/TryStuff/data/csv/IllinoisData.csv')
def read_csv_file(filename): parts = list(filename.parts) # parts = ['/', 'media', '/', 'stubens', '/', 'DataDrive-3XT','/', 'projs', '/', 'T-Z', '/', 'T', '/', 'TryStuff', '/', 'data', '/', 'csv', '/', 'IllinoisData.csv'] parts[-1] = f"{filename.stem}Modified{filename.suffix}" # parts[-1] = 'IllinoisDataModified.csv' # parts = ['/', 'media', '/', 'stubens', '/', 'DataDrive-3XT','/', 'projs', '/', 'T-Z', '/', 'T', '/', 'TryStuff', '/', 'data', '/', 'csv', '/', 'IllinoisDataModified.csv'] parts[0] = '' # removes '/' from index 0 because join will add it back again # parts = ['media', '/', 'stubens', '/', 'DataDrive-3XT','/', 'projs', '/', 'T-Z', '/', 'T', '/', 'TryStuff', '/', 'data', '/', 'csv', '/', 'IllinoisDataModified.csv'] outfilename = Path(f"{'/'.join(parts)}") # join fileparts back together # outfilename = '/media/stubens/DataDrive-3XT/projs/T-Z/T/TryStuff/data/csv/IllinoisDataModified.csv' print(f"new output file name: {outfilename}") # will print # '/media/stubens/DataDrive-3XT/projs/T-Z/T/TryStuff/data/csv/IllinoisDataModified.csv' # open two files, filename as input (fp), outfilename as output (fout) with filename.open() as fp, outfilename.open('w') as fout: # set csv reader to flename (fp) crdr = csv.reader(fp, delimiter=',') # set csv writer to outfilename (fout), delimiter = ',' cwrtr = csv.writer(fout, delimiter=',') # for each row in crdr (csv input) for row in crdr: # print the row print(row) # ... # Your code goes here # ... # write modified row cwrtr.writerow(row)
