pythonopen文件，取出某列，转化成天，然后和当前时间【从1月1日到现在多少天】做比较，得出不可用百分比

#!/usr/bin/python
import time,datetime
from datetime import date

file = '/Users/jian.wang13/code/test/0629shijian.txt'
list = []
with open(file,'r',encoding='utf-8') as f:
    for i in f:
        tmp = i.strip()
        list.append(tmp)
current_data = datetime.datetime.now().strftime('%Y-%m-%d')
print(current_data)
a,b,c = map(int,current_data.split('-'))
print(a,b,c)
num = date(a,b,c)
yuan_dan = date(num.year+0,1,1)
#jisuan = yuan_dan - num
jisuan = num - yuan_dan
jisuan1 = str(jisuan)
jisuan1 = jisuan1.split(' ')
jisuan2 = jisuan1[0]
print(jisuan2)
print(list)
sum = 0
for i in list:
    sum += float(i)
print((sum/float(jisuan2))*100)
