If Else语句的问题

Question

我是从零开始学习Python的，因为我没有太多的编码背景。在这个特殊的练习中，我的任务是获取一个文本文件，删除空格和逗号，然后将其打印为七行(我已经这样做了)。现在，我完成了任务，我需要在每行上的单个int之前显示实际的、递增的时间，同时还向读取'blank blank '的行添加一天。'

我尝试了几种方法，但似乎无法同时得到两个标准。下面是我写的代码:

from datetime import datetime
from datetime import timedelta
with open("C:UserscurnutteDesktopAssignmentPython ScriptsPython exampleRandomFile.txt", "r") as inp:
    with open("C:UserscurnutteDesktopAssignmentPython ScriptsPython exampleRandomFileOutput.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))

这里是'RandomFile:'

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

使用我提供的代码，这里是我收到的'RandomFileOutput':

2016-06-28 13:47:56.106000: 13

直到我添加了最后一个if, else语句，我收到的输出是:

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

谁能告诉我我做错了什么?

我认为你的缩进是错误的，你应该检查total的类型，而不是total==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))
