从通过树莓上的 cron 运行的 python 脚本恢复打印输出

Question

I have been running a python script as a cron job to read data from a serial port via a raspberry pi. The data was supposed to be stored in a database but this did unfortunately not happen due to a bug in my code. However, I did have a print statement of the read-out data in my python code.

Unfortunately, I did not redirect output from the python script in the crontab configuration. Is there any other default place where this output would be logged? Until now the the logging for /etc/rsyslog.conf for *cron was commented out but there is a catch-all line that was active and seems to include cron jobs, however I could not find anything in the /var/log/messages output

It is hard for me to rerun my experiment and the data lost would be a blow to my research.

It did not format in the comments so here is some code. I have not run it, because I do not have pyautogui , but I hope it will help you archive screenshots of your code. Test this before you rely on it. :

import pyautogui

saveDir = r"PUT PATH HERE THAT ENDS WITH BACKSLASH --> C:PATH\"
scrollSpeed = 10  # Change this for different scrolling speed
count = 10**2 # Change for different amount of screenshots

for i in range(count):
   myScreenshot = pyautogui.screenshot()
   myScreenshot.save(f"{saveDir}screenshot{i}.png")

   pyautogui.scroll(scrollSpeed*-1)
