Question

试图使它工作一段时间，不知道为什么它不能让我将字符串更改为日期时间，我是Python新手，请帮忙。

counts_by_hour = {}
comment_by_hour = {}


for row in result_list3:
    date = "10/15/2015 16:38"
    date2 = dt.datetime.strptime(date, "%m/%d/%Y %h:%M")

ValueErrorTraceback (most recent call last)

    330             # IndexError only occurs when the format string is "%"
    331             except IndexError:

ValueError: 'h' is a bad directive in format '%m/%d/%Y %h:%M'```

Answer 1

%H使用了几个小时。因此，您的代码应如下所示：

date2 = dt.datetime.strptime(date, "%m/%d/%Y %H:%M")

'h'是格式为'％m /％d /％Y％h：％M'的错误指令
