과 같은 출력을 리턴

여기 분당 가동 중지 시간에 대한 세부 정보가 있으며 날짜까지 백분율로 변환하고 싶습니다. 예를 들어 ->

사용자 입력 :

1.9.2016,1.11.2016,1.1.2016

출력 : 가용성 계산 뒤에

Total Downtime is 30 min from 1.9.2016 08:21:33 & Availability percentage from selected date to till date : xx.xxx% 
Total Downtime is 28 min from 1.11.2016 08:26:33 & Availability percentage from selected date to till date : yy.yyy% 
Total Downtime is 30 min from 1.11.2016 08:26:33 & Availability percentage from selected date to till date : zz.zzz% 

논리는 것

total number of min down from date(which is retrieved)/total number of min till date * 100 

나는이 부분에 갇혀있다. 달성 할 수 있는가? 어떤 도움이 좋을지 !! 대신 날짜 None와 processText()를 실행하면 아래

total_down, start = processText(data, None) 

때

Answer 1

는 당신이 분의 총 수를 얻을 당신은 비율을 계산하는 데 사용할 수 있습니다.

percentage = (down/total_down) * 100 

당신이 분의 총 수를 원하는 경우 그 다음 아래로 또는 위로 때 당신은 점

def calculate(): 

    all_dates = entry.get().split(',') 
    print(all_dates) 
    all_dates = [date.strip() for date in all_dates] 

    # calculate total number of minutes when it was down 
    total_down, start = processText(data, None) # <-- None 

    print('total_down:', total_down) 

    txt = '' 

    for current_date in all_dates: 
     down, start = processText(data, current_date) 

     # calculate percetage 
     percentage = (down/total_down) * 100 

     # use string formatting {:.2f} to display only two digits after dot 
     txt += "Total Downtime is {} min from {} ({:.2f}%)\n".format(down, start, percentage) 

    textVar.set(txt)

후 두 자리 숫자를 표시하는 {:.2f}를 포맷 문자열을 사용할 수 있습니다 processText을 변경하고 새 매개 변수 (예 : word)를 추가하여 direction이 맞는지 확인해야합니다. DOWN 또는 UP 또는 둘 다 (word = None)

def processText(lines, selected_date, word="DOWN"): 

    total = 0 
    start = None 

    print(selected_date) 
    # if there is `selected_date` then convert to `datetime`

      selected_date = datetime.datetime.strptime(selected_date, "%d.%m.%Y") 
     except AttributeError as ex: 
      print("ERROR:", ex) 
      selected_date = None 

    # calculate time 
    for direction, t1, t2, seconds in lines: 

     if not word or word == direction: 

      # if `selected_date` then filter times 
      if selected_date and t1 <= selected_date: 
       continue 

      if not start: 
       start = t1.strftime("%d.%m.%Y %H:%M:%S") 

      total += seconds 

    # convert to minutes after summing all second 
    total = total//60 

    return total, start 

def calculate(): 

    all_dates = entry.get().split(',') 
    print(all_dates) 
    all_dates = [date.strip() for date in all_dates] 

    # calculate total number of minutes when it was down and up 
    total_down, start = processText(data, None, None) 

    print('total_down:', total_down) 

    txt = '' 

    for current_date in all_dates: 
     down, start = processText(data, current_date, "DOWN") 
     percentage = (down/total_down) * 100 
     txt += "Total Downtime is {} min from {} ({:.2f}%)\n".format(down, start, percentage) 

    textVar.set(txt)
