python时间戳与时间字符串的转化

1、获取时间戳

time.time()
datetime.datetime.now().timestamp()
pytz.datetime.datetime.now().timestamp()
calendar.datetime.datetime.now().timestamp()

2、获取时间字符串

# 不带时区
time.strftime('%Y-%m-%d %H:%M:%S')
datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S')
pytz.datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S')
calendar.datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S')
# 带时区
pytz.datetime.datetime.now(tz=pytz.timezone('Asia/Shanghai')).strftime('%Y-%m-%d %H:%M:%S')
datetime.datetime.now(tz=pytz.timezone('Asia/Shanghai')).strftime('%Y-%m-%d %H:%M:%S')
calendar.datetime.datetime.now(tz=pytz.timezone('Asia/Shanghai')).strftime('%Y-%m-%d %H:%M:%S')

3、时间字符串转时间戳

# 不带时区
time.mktime(time.strptime('2023-03-28 12:00:00', "%Y-%m-%d %H:%M:%S"))
datetime.datetime.strptime('2023-03-28 12:00:00', "%Y-%m-%d %H:%M:%S").timestamp()
pytz.datetime.datetime.strptime('2023-03-28 12:00:00', "%Y-%m-%d %H:%M:%S").timestamp()
calendar.datetime.datetime.strptime('2023-03-28 12:00:00', "%Y-%m-%d %H:%M:%S").timestamp()
# 带时区
datetime.datetime.strptime('2023-03-28 12:00:00', '%Y-%m-%d %H:%M:%S').replace(tzinfo=pytz.timezone('Europe/Paris')).timestamp()
pytz.datetime.datetime.strptime('2023-03-28 12:00:00', '%Y-%m-%d %H:%M:%S').replace(tzinfo=pytz.timezone('Europe/Paris')).timestamp()
calendar.datetime.datetime.strptime('2023-03-28 12:00:00', '%Y-%m-%d %H:%M:%S').replace(tzinfo=pytz.timezone('Europe/Paris')).timestamp()

4、时间戳转时间字符串

# 不带时区
time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(time.time()))
pytz.datetime.datetime.fromtimestamp(time.time()).strftime('%Y-%m-%d %H:%M:%S')
datetime.datetime.fromtimestamp(time.time()).strftime('%Y-%m-%d %H:%M:%S')
calendar.datetime.datetime.fromtimestamp(time.time()).strftime('%Y-%m-%d %H:%M:%S')
# 带时区
pytz.datetime.datetime.fromtimestamp(time.time(), pytz.timezone('Asia/Shanghai')).strftime('%Y-%m-%d %H:%M:%S')
datetime.datetime.fromtimestamp(time.time(), pytz.timezone('Asia/Shanghai')).strftime('%Y-%m-%d %H:%M:%S')
calendar.datetime.datetime.fromtimestamp(time.time(), pytz.timezone('Asia/Shanghai')).strftime('%Y-%m-%d %H:%M:%S')
