ユーザー入力の処理データ

Question

私は、テキストファイルをアップロードしてからユーザー入力を提供し、さらにユーザー入力処理に従ってシナリオを作成しました。

サンプルファイル：

DOWN 07.09.2016 08:21:33 - 07.09.2016 08:23:33 
UP 07.11.2016 09:41:07 - 09.11.2016 09:20:33 
DOWN 09.11.2016 08:26:33 - 09.11.2016 08:46:33 
UP 09.11.2016 08:23:33 - 09.11.2016 08:25:33 
DOWN 09.11.2016 08:36:33 - 09.11.2016 08:41:33 
DOWN 10.11.2016 08:36:33 - 10.11.2016 08:39:33

は形式Date1.Month1.Year1、Date2.Month2.Year2で日付を選択するために私を促し...（に応じて、 。日付の数字入力）

として出力を返す：

Total Downtime is x min from date1.month1.year1 xx:xx:xx(time1) 
Total Downtime is y min from date2.month2.year2 yy:yy:yy(time2) 

ここでは、ダウンタイムの詳細を分単位で示しています。これを日付までパーセンテージで変換したいと思います。例えば ​​- >

ユーザ入力：

1.9.2016,1.11.2016,1.1.2016

出力：

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% 

可用性計算の背後にあるロジックは

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

あろう

私はこの部分で立ち往生していますが、これは達成可能ですか？どんな助けも素晴らしいだろう！

Answer 1

あなたは日付の代わりにNoneでprocessText()を実行した場合、それがダウンし

total_down, start = processText(data, None) 

だったとあなたはパーセンテージを計算するために使用することができたとき、あなたは数分の合計数を取得します。

percentage = (down/total_down) * 100 

、それがその後、ダウンまたはアップしたとき、あなたは数分の合計数をしたい場合は、ドット

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) 

---

後に2桁のみを表示するように{:.2f}の書式文字列を使用することができますprocessTextを変更し、新しいパラメータ（すなわち、word）を追加して、directionがDOWNまたはUPまたは両方（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` 
    if selected_date: 
     try: 
      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)
