这应该行得通

import time

now = datetime.now()
current_time = now.strftime("%H:%M:%S")
print("The current time is", current_time)

与Harley的答案类似，但使用str（）函数实现一种更快速、更易于阅读的格式：

>>> from datetime import datetime
>>> str(datetime.now())
'2011-05-03 17:45:35.177000'

使用time.strftime（）：

>>> from time import gmtime, strftime
>>> strftime("%Y-%m-%d %H:%M:%S", gmtime())
'2009-01-05 22:14:39'

now（）的属性可用于获取python中的当前时间：

# importing datetime module for now()
import datetime
    
# using now() to get current time
current_time = datetime.datetime.now()
    
# Printing attributes of now().
print ("The attributes of now() are : ")
    
print ("Year : ", end = "")
print (current_time.year)
    
print ("Month : ", end = "")
print (current_time.month)
    
print ("Day : ", end = "")
print (current_time.day)
    
print ("Hour : ", end = "")
print (current_time.hour)
    
print ("Minute : ", end = "")
print (current_time.minute)
    
print ("Second : ", end = "")
print (current_time.second)
    
print ("Microsecond : ", end = "")
print (current_time.microsecond)

from datetime import datetime
datetime.now().strftime('%Y-%m-%d %H:%M:%S')

示例输出：“2013-09-18 11:16:32”

请参阅strftime指令列表。

对UTC日期时间、本地日期时间使用此方法，并转换上午和下午

import pytz
from datetime import datetime

#UTC Time
print("UTC Date and time")
epoch: datetime =datetime.now().replace(tzinfo=pytz.utc)
print(epoch)

#local date and time
print("Local Date and time")
today = datetime.now()
local_time = today.strftime("%Y-%M-%d:%H:%M:%S")
print(local_time)

#convert time to AM PM format
print("Date and time AM and PM")
now = today.strftime("%Y-%M-%d:%I:%M %p")
print(now)
