python - 获取程序运行的时间（Python）

Question

我正在编写一个 Python 脚本，我要让它说上次更新：然后是它上次更新的时间，但我不确定如何

这是示例代码

from PIL import ImageDraw
import ctypes, time
import urllib
import manipulate
import datetime



font_size = 50
font_color = "red"

font = ImageFont.load_default() 
img = Image.open('bg.bmp')
draw = ImageDraw.Draw(img)

time = datetime.datetime.now()


draw.text((650, 450),'                      CURRENT GRADES' )
draw.text((650, 500), 'Period 1: Geography -----------------------------')
draw.text((650, 550), 'Period 2: Francais-------------------------------')
draw.text((650, 600), 'Period 3: Science--------------------------------')
draw.text((650, 650), 'Period 4: P.E------------------------------------')
draw.text((650, 700), 'Period 5: Algebra 9------------------------------')
draw.text((650, 750), 'Period 6: LA-------------------------------------')
draw.text((650, 800), 'Last Updated:'(time))
draw = ImageDraw.Draw(img)
draw = ImageDraw.Draw(img)
img.save('mod_bg.bmp')







pathToBmp = "C:\Python27\mod_bg.bmp"
SPI_SETDESKWALLPAPER = 20  
ctypes.windll.user32.SystemParametersInfoA(SPI_SETDESKWALLPAPER, 0, pathToBmp ,
                                       0)

最后更新的地方是我需要时间来

当我尝试它时，我得到了这个错误

Traceback (most recent call last):
File "C:\Python27\Project.py", line 28, in <module>
draw.text((650, 800), 'Last Updated:'(time))
TypeError: 'str' object is not callable

如果有人可以帮忙，请做！谢谢！

Answer 1

采用datetime

import datetime
now = datetime.datetime.now()
draw.text((650, 800), 'Last Updated: {0}'.format(now))

Answer 2

问题是'Last Updated:'(time)部分。您在字符串后面加上括号，因此将其视为一个函数。你应该这样做'Last Updated: %s' % time。
