time.time()
生成一个float类型的时间戳
time.localtime()
- 返回当前的时间类型为struct_time类型的时间
import time
t1 = time.localtime()
print(t1, type(t1))
#time.struct_time(tm_year=2020, tm_mon=1, tm_mday=23, tm_hour=16, tm_min=51, tm_sec=15, tm_wday=3, tm_yday=23, tm_isdst=0) <class 'time.struct_time'>
- 可以接受一个为整数的时间戳类型的时间
import time
t1 = time.localtime(int(time.time()))
print(t1, type(t1))
#time.struct_time(tm_year=2020, tm_mon=1, tm_mday=23, tm_hour=16, tm_min=54, tm_sec=39, tm_wday=3, tm_yday=23, tm_isdst=0) <class 'time.struct_time'>
time.asctime()
- 返回当前时间的这种格式的字符串
time.strftime()
- 传入格式struct_time,返回按照format格式格式化后的时间字符串
t5 = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime())
print(t5, type(t5))
格式占位符参考
%Y Year with century as a decimal number.
%m Month as a decimal number [01,12].
%d Day of the month as a decimal number [01,31].
%H Hour (24-hour clock) as a decimal number [00,23].
%M Minute as a decimal number [00,59].
%S Second as a decimal number [00,61].
%z Time zone offset from UTC.
%a Locale's abbreviated weekday name.
%A Locale's full weekday name.
%b Locale's abbreviated month name.
%B Locale's full month name.
%c Locale's appropriate date and time representation.
%I Hour (12-hour clock) as a decimal number [01,12].
%p Locale's equivalent of either AM or PM.
time.strptime()
- 将字符串时间转化为struct_time,time.strftime()的一个逆向操作
