datetime with every screenshot name

[buran]

not working pro the just create one file ( qan-2018-08-27 05 ) not 10 files :)
could u please try to modify my code i need to use code that i write and understand not new one

well, don't tell me it's not working.

import os
#import pyautogui
import datetime

d = datetime.datetime.now()
for i in range(10):
    file_name = os.path.join('C:/Users/root/Desktop/test', 'qan-{:%Y-%m-%d %H:%M}({}).png'.format(d, i))
    # file_name = os.path.join('C:/Users/root/Desktop/test', f'qan-{d:%Y-%m-%d %H:%M}({i}).png') # this is better, for python 3.6+
    #pic = pyautogui.screenshot(file_name)
    print(file_name)

Output:
C:/Users/root/Desktop/test/qan-2018-08-27 13:40(0).png
C:/Users/root/Desktop/test/qan-2018-08-27 13:40(1).png

as you can see for yourself it produce 10 different file_names. So if it doesn't work, it's not due to changes I did. It's something with what you did. As you can see my code produce the exact file name you want, not the one you show (qan-2018-08-27 05). If I have to guess - I put my money that the problem is in the space between the date and time. But it was in your code too. You may want to change the format string to something like %Y-%m-%d_%H:%M or better %Y%m%d%H%M
Actually, I'm doing exactly what you asked - fix your code, to use the right tools and to be more pythonic.
It's generally discouraged to use string concatenation, in favor of more advanced string-formatting. One of disadvantages of concatenation is you need to cast everything that is not str to string in order to be able to concatenate. It yields ugly, non-pythonic code (sorry, but that's fact).
When you want to construct paths, use the tools that python provides. In this case string concatenation is even more discouraged.
In addition it's better to use for loop instead of while loop when you want to loop exact number of times, that you know in advance.

your code would be

import pyautogui
import datetime
 
q = datetime.datetime.now()
 
d= q.strftime("%Y-%m-%d %H:%M")
 
 
 
x = 0
 
while x<10:
     
    pic = pyautogui.screenshot(r'C:\Users\root\Desktop\test\qan-'+d + '(' + str(x)+').png')
     
    x+=1 

do you honestly think it's better?
I suggest to learn from what you are offered and ask questions if there is something you don't understand instead of stick to what you have written so far.
