dictfiles = dict()
countfiles(dictfiles, lstTokens, repo)
print('Total number of files: ' + str(len(dictfiles)))

file = repo.split('/')[1]
fileOutput = 'data/file_' + file + '.csv'
rows = ["Filename", "Touches"]
fileCSV = open(fileOutput, 'w')
writer = csv.writer(fileCSV)
writer.writerow(rows)

bigcount = None
bigfilename = None
for filename, count in dictfiles.items():
    rows = [filename, count]
    writer.writerow(rows)
    if bigcount is None or count > bigcount:
        bigcount = count
        bigfilename = filename
fileCSV.close()
print('The file ' + bigfilename + ' has been touched ' + str(bigcount) + ' times.')```
