If If語句的問題

Question

我從頭開始學習Python，因爲我沒有太多編碼背景。在這個特別的練習中，我被賦予了一個文本文件的任務，刪除空格和逗號，然後將它打印成七行（我已經完成）。現在，我完成了任務，我需要顯示真實，在每行之前增加單個int之前的時間，同時在讀取'空白空白'的行上添加一天。

我試過幾種方法，似乎無法同時出現兩種標準。這是我寫的代碼：

from datetime import datetime 
from datetime import timedelta 

with open("C:\Users\curnutte\Desktop\Assignment\Python Scripts\Python example\RandomFile.txt", "r") as inp: 
    with open("C:\Users\curnutte\Desktop\Assignment\Python Scripts\Python example\RandomFileOutput.txt", "w") as outp: 

    clock = datetime.now() 

    for line in inp.readlines(): 
     total = 0 
     line = line.strip() 
     parts = line.split(",") 
     for part in parts: 

      try: 
       num = int(part) 
       total += num 

      except ValueError: 
       total = (" ".join(parts)) 
       break 

    #for line in inp: 

    if total == int: 
     total_time = clock + timedelta(seconds = 1) 
     print (clock + timedelta (seconds = 1)) 
    else: 
     total_time = clock + timedelta(days = 1) 
     print (clock + timedelta (days = 1)) 

    outp.write("%s: " % total_time) 

    outp.write('{}\n'.format(total)) 

這裏是 'RandomFile：'

1,2 
2,3 
3,4 
4,5 
blank,blank 
5,6 
6,7 

隨着我所提供的代碼，這裏是 'RandomFileOutput' 我收到：

2016-06-28 13：47：56.106000：13

直到我添加了最後一個if，else語句我收到的輸出是：

2016-06-28 13:51:19.709000: 3 
2016-06-28 13:51:19.709000: 5 
2016-06-28 13:51:19.709000: 7 
2016-06-28 13:51:19.709000: 9 
2016-06-28 13:51:19.709000: blank blank 
2016-06-28 13:51:19.709000: 11 
2016-06-28 13:51:19.709000: 13 

任何人都可以闡明我做錯了什麼？

我覺得你的縮進是錯誤的，你應該檢查總數的類型，而不是總== INT：

from datetime import datetime 
from datetime import timedelta 

with open("RandomFile.txt", "r") as inp: 
    with open("RandomFileOutput.txt", "w") as outp: 

     clock = datetime.now() 

     for i, line in enumerate(inp.readlines()): 
      total = 0 
      line = line.strip() 
#    print(line) 
      parts = line.split(",") 
      for part in parts: 

       try: 
        num = int(part) 
        total += num 

       except ValueError: 
        total = (" ".join(parts)) 
        break 

      #for line in inp: 
      print(type(total)) 
      if type(total) == int: 
       total_time = clock + timedelta(seconds = 1) 
       print (clock + timedelta(seconds = 1)) 
      else: 
       total_time = clock + timedelta(days = 1) 
       print (clock + timedelta(days = 1)) 
      outp.write("%s: " % total_time) 

      outp.write('{}\n'.format(total)) 

打印：
