如何检查我的年月日在Python中是否正确

Question

已连接到Google Calendar API的Python项目。当我开始运行程序时，“今天”部分运行良好。但是，当我在Google日历上设置另一个时间表时，假设今天是2月13日。然后我将日期设置为2月16日，并尝试在python上调用它，但返回“未发现即将发生的事件”。我的年份或其他年份有问题吗？我在youtube上观看了本教程“ Python语音助手教程＃4-从语音中获取日期”，我不知道问题出在哪里。我按部就班地观看了整个视频，但仍然出现错误。先感谢您。

def get_date（text）：文字= text.lower（）今天= datetime.date.today（）

if text.count("today") > 0:
    return today

day = -1
day_of_week = -1
month = -1
year = today.year

for word in text.split():
    if word in MONTHS:
        month = MONTHS.index(word) + 1
    elif word in DAYS:
        day_of_week = DAYS.index(word)
    elif word.isdigit():
        day = int(word)
    else:
        for ext in DAY_EXTENTIONS:
            found = word.find(ext)
            if found > 0:
                try:
                    day = int(word[:found])
                except: 
                    pass

if month < today.month and month != -1:
    year = year+1

# This is slighlty different from the video but the correct version
if month == -1 and day != -1:  # if we didn't find a month, but we have a day
    if day < today.day:
        month = today.month + 1
    else:
        month = today.month

if month == -1 and day == -1 and day_of_week != -1:
   current_day_of_week = today.weekday()
   dif = day_of_week - current_day_of_week

   if dif < 0:
        dif += 7
        if text.count("next") >= 1:
            dif += 7

   return today + datetime.timedelta(dif)

if month == -1 or day == -1:
    return None

if day != -1:  # FIXED FROM VIDEO
   return datetime.date(month=month, day=day, year=year)

仅使用dateutil库将字符串解析为日期（您需要pip install python-dateutil）

from dateutil.parser import parse

date_given = parse(text)
print(date_given)

它倾向于做正确的事...

如果需要更明确的控制，则应使用

date_given = datetime.datetime.strptime(formatString, dateString)

如果您需要查看两个日期之间的差异，请减去它们

datetime.datetime.now() - date_given
