Python-如何对文件中的值求和

Question

所以我有一个文件。其中有 3 行，每行告诉 Name;sport:points

Kevin;Football:604,196,47;Golf:349,0,0;Tennis:797,426,124
Julia;Football:350,254,1;Golf:242,58,38
Bob;Football:260,18,0

我有代码，但我不知道如何计算每项运动的分数

f=open("points.txt", "r")
s=f.readlines()
p=str(s)

for line in s:
    printnum=0
    printnum+=float(line)



    for line in s:
        if p.isdigit():
            total=0
            for number in s:
                total+=int(number)
                print(total)

所以结果应该是这样的

Alvin:
- Football: 278
Kevin:
- Football: 847
- Golf: 349
- Tennis: 1347
Sam:
- Football: 605
- Golf: 338

所以基本上我不知道热求和键值

Answer 1

from ast import literal_eval as leval

my_dict = {}
for line in s:
    name, *sports = line.split(';')
    my_dict[name] = {sport.split(':')[0]: sum(leval(sport.split(':')[1])) for sport in sports}

for player in my_dict:
    print('{}:'.format(player))
    for sport in my_dict[player]:
        print(' - {}: {}'.format(sport, my_dict[player][sport]))
