I want to save the picture as LogData.jpg, but I want to number every time I turn the code is turned.
예를 들면 LogData1.jpg,LogData2.jpg, ...
Now, it's always overwritten in one file.
raspberry-pi python
for in range (1): Delete the loop and try writing it like this instead.
import datetime
file_dt = datetime.datetime.now().strftime('%Y%m%d%H%M%S')
File_Justin = open("LogData%s.jpg"%file_dt, "ab")
그러면 대충 LogData20230103162241.jpg, LogData20230103162242.jpg, ... That's how the file name will be created.
If you look at the actual usage scenario, I think the timestamp would be better than the serial number starting with 1, so I recommend this.
