时间模块练习

1.年的日历图

import calendar
from datetime import date
mydate = date.today()
year_calendar_str = calendar.calendar(2019)
print(f"{mydate.year}年的日历图：{year_calendar_str}\n")

2.判断是否为闰年
import calendar
from datetime import date

mydate = date.today()
is_leap = calendar.isleap(mydate.year)
print_leap_str = "%s年是闰年" if is_leap else "%s年不是闰年\n"
print(print_leap_str % mydate.year)


3.月的日历图
import calendar
from datetime import date

mydate = date.today()
month_calendar_str = calendar.month(mydate.year, mydate.month)

print(f"{mydate.year}年-{mydate.month}月的日历图：{month_calendar_str}\n")


4.月有几天
import calendar
from datetime import date

mydate = date.today()
weekday, days = calendar.monthrange(mydate.year, mydate.month)
print(f'{mydate.year}年-{mydate.month}月的第一天是那一周的第{weekday}天\n')
print(f'{mydate.year}年-{mydate.month}月共有{days}天\n')


5.月第一天
from datetime import date
mydate = date.today()
month_first_day = date(mydate.year, mydate.month, 1)
print(f"当月第一天:{month_first_day}\n")

6.月最后一天
from datetime import date
import calendar
mydate = date.today()
_, days = calendar.monthrange(mydate.year, mydate.month)
month_last_day = date(mydate.year, mydate.month, days)
print(f"当月最后一天:{month_last_day}\n")

7.获取当前时间
from datetime import date, datetime
from time import localtime

today_date = date.today()
print(today_date)  # 2019-12-22

today_time = datetime.today()
print(today_time)  # 2019-12-22 18:02:33.398894

local_time = localtime()
print(strftime("%Y-%m-%d %H:%M:%S", local_time))  # 转化为定制的格式 2019-12-22 18:13:41

8.字符时间转时间
from time import strptime

# parse str time to struct time
struct_time = strptime('2019-12-22 10:10:08', "%Y-%m-%d %H:%M:%S")
print(struct_time) # struct_time类型就是time中的一个类

# time.struct_time(tm_year=2019, tm_mon=12, tm_mday=22, tm_hour=10, tm_min=10, tm_sec=8, tm_wday=6, tm_yday=356, tm_isdst=-1)
