Beginning Python

Starting with creating our data file data.txt:

data.txt
12
54
7
332
54
1
0

The logic in this script is identical but instead of having total, count and mean as separate variables, we have collected them into a single dictionary:

file.py
stats = {"sum": 0, "count": 0}

with open("data.txt") as f:
    for line in f:
        number = int(line)
        stats["sum"] += number
        stats["count"] += 1

if stats["count"] > 0:
    stats["mean"] = stats["sum"] / stats["count"]

print(stats)
$
python file.py

{'sum': 460, 'count': 7, 'mean': 65.71428571428571}
