Before Change

t_char = 0
try:
    with open(file_name) as f:
        line = f.readline()
        t_char += len(line)
        while line:
            count += 1
            line = f.readline()
            t_char += len(line)
except FileNotFoundError as e:
    print(e)

After Change

        // Source: https://stackoverflow.com/a/1019572
        count = (sum(1 for line in f))
        f.seek(0)
        t_char = (sum([len(line) for line in f]))
except FileNotFoundError as e:
    print(e)
    sys.exit(1)
