Question

所以我提出了这个错误

ValueError：时间数据'8/16/2016 9:55'与格式'％m /＆d /％Y不匹配％H：％M'。

我知道％m是月份的格式，带有两位数字（零填充）。正如我们所看到的，“ 8”（八月）没有填充零。这是这个错误的问题吗？以及我该如何解决？

import datetime as dt
result_list = []
for a in ask_posts:
    result_list.append([a[6], int(a[4])])
counts_by_hour = {}
comments_by_hour = {}
date_format = '%m/&d/%Y %H:%M'

for row in result_list:
    date = row[0]
    comment = row[1]
    time = dt.datetime.strptime(date, date_format).strftime("%H")
    ``` I want  to extract the Hour only```
    if time not in counts_by_hour:
        counts_by_hour[time] = 1
        comments_by_hour[time] = comment
    else:
        counts_by_hour[time] += 1
        comments_by_hours[time] += comment

您的日期格式有错误％不是＆

import datetime as dt
result_list = []
for a in ask_posts:
    result_list.append([a[6], int(a[4])])
counts_by_hour = {}
comments_by_hour = {}
date_format = '%m/%d/%Y %H:%M' #  change & with %

    for row in result_list:
        date = row[0]
        comment = row[1]
        time = dt.datetime.strptime(date, date_format).strftime("%H")
        ``` I want  to extract the Hour only```
        if time not in counts_by_hour:
            counts_by_hour[time] = 1
            comments_by_hour[time] = comment
        else:
            counts_by_hour[time] += 1
            comments_by_hours[time] += comment

ValueError：时间数据不匹配
