python编程实现

Question

有这样一个txt文本。数据如下：

Domain Configured

Clock freq.(MHz) Active time(seconds)
307.20 0.78
384.00 0.00
409.60 0.00
576.00 0.03
614.40 0.00
768.00 0.00
940.80 0.00
1171.20 0.80
1324.80 0.00
1401.60 0.01
Power collapse time(seconds): 14729.63
Low Power Island time(seconds): 1.30
Current core clock(MHz): 307.20
Total time(seconds): 14732.55

需要计算每行乘积之和（ΣClock freq* Active time）除以（1401.60*Total time）的值
1401.60是最后一个Clock freq

请展示python实现代码

非常感谢

with open('test.txt', 'r') as f:
    lines = [line.replace('\n', '') for line in f.readlines() if line[0] in ['1', '2', '3', '4', '5', '6', '7', '8', '9', '0']]
with open('test.txt', 'r') as f:
    seconds = float(f.readlines()[-2].replace('\n', '').split(': ')[-1])
    # seconds = float(f.readlines()[-1].replace('\n', '').split(': ')[-1])
sum = 0
for line in lines:
    a, b = line.split(' ')
    s = float(a) * float(b)
    sum += s
final = float(lines[-1].split(' ')[0])
print('最后结果为:', sum/(seconds*final))
