1.时间戳转标准时间

import datetime

def timestamp_format(timestamp): """将时间戳转换为时间""" timestamp_10 = int(int(timestamp)/1000) if len(str(timestamp))>10 else int(timestamp) time_local = time.localtime(timestamp_10) format_time = time.strftime("%Y-%m-%d %H:%M:%S", time_local) return format_time

2.自定义时分秒：

def hms(): """随机获取时分秒""" hour_list = list(range(0, 24)) min_list = list(range(0, 60)) h = random.choice(hour_list) m = random.choice(min_list) s = random.choice(min_list) hms = '%02d:%02d:%02d' % (h, m, s) return hms def get_day(num): """获取num天对应日期""" now_time = datetime.datetime.now() change_time = now_time + datetime.timedelta(days=num) format_time = change_time.strftime('%Y-%m-%d') return format_time

def get_hour(num): """根据当前时间格式化num小时前的时间""" now_time = datetime.datetime.now() change_time = now_time + datetime.timedelta(hours=num) format_time = change_time.strftime('%Y-%m-%d %H:%M:%S') return format_time

def get_minute(num): """根据当前时间格式化num分钟前的时间""" now_time = datetime.datetime.now() change_time = now_time + datetime.timedelta(minutes=num) format_time = change_time.strftime('%Y-%m-%d %H:%M:%S') return format_time 3.将不同的时间格式标准化 def format_time(timer: str): day_dict = {"今天":0,"昨天":1,"前天":2}

if timer == "刚刚": return datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S")

# 形如5小时前 3 小时前 elif "小时前" in timer: num = re.findall('(d+)', timer)[0] t1 = int(num) return get_hour(-t1)

# 形如50分钟前 30 分钟前 elif "分钟前" in timer:

num = re.findall('(d+)', timer)[0] t1 = int(num) return get_minute(-t1)

# 形如今天 12:23,昨天，昨天 12:23,前天，前天 12:23 elif "天" in timer: #今天，昨天，前天 if " " not in timer: return get_day(-day_dict[timer]) + " " + hms() else: hour_min = timer.split()[-1] day = timer.split()[0] nyr = get_day(-day_dict[day]) return nyr + " " + hour_min + ":00"

#形如 9月5日 12:20 elif "月" in timer and "年" not in timer: year = datetime.datetime.now().year month_day_tuple = re.findall('(d+)月(d+)日',timer)[0] month_day = "%02d-%02d"%(int(month_day_tuple[0]),int(month_day_tuple[1])) hour_min = timer.split()[-1] format_time = "{}-{} {}:00".format(year,month_day,hour_min) return format_time

#2020年05月08日 12:12:12 elif "年" in timer and "日" not in timer: return re.sub("年|月","-",timer).replace("日","")

else: return timer

4.还有格式如同 周六 12:12这种格式，不过一般只限于上周六周日，格式化方式如下

import datetime from dateutil.relativedelta import relativedelta from dateutil.rrule import * def weektime(self,post_time): """ 获取上一个周几的时间 """ current_time = datetime.datetime.now() week = post_time.split(" ")[0] hour_min = post_time.split(" ")[-1] if week == "周六": thatday = current_time + relativedelta(weekday=SA(-1)) else: thatday = current_time + relativedelta(weekday=SU(-1)) return str(thatday.date()) + " " + hour_min + ":00"
