Understanding crontab entry - unix

Question

I've got this Unix script and I'm trying to translate it to Python. The problem is I don't understand Unix and I have no idea what any of it means.
This is the code:
1 17-23 * * * curl -X PUT -d EM_OperatingMode=10 --header 'Auth-Token: 512532eb-0d57-4a59-8da0-e1e136945ee8' http://192.168.1.70:80/api/v2/configurations

Answer 1

The code you took is in crontab of Unix system. Let's split the code into two parts.
The first part, 1 17-23 * * * , represents a schedule. It means between 17:00 to 23:00, the program runs every hour at the first minute of that hour. Crontab follows min hour day month weekday. (Refer crontab guru.)
The second part, curl -X PUT -d EM_OperatingMode=10 --header 'Auth-Token: 512532eb-0d57-4a59-8da0-e1e136945ee8' http://192.168.1.70:80/api/v2/configurations, represents a PUT request to an URL.
curl is a program used to communicate with a server. You use a browser to interact with a server right. You can think of curl as a command line tool to do the same. The parameter contains PUT request which updates data in the server. Here EM_OperationMode=10 is being passed to the server for updating. --header represents parameters to be sent to the URL. Here an authentication token is being sent to the URL to validate its access. Finally, the URL for communication is http://192.168.1.70:80/api/v2/configurations.
So, the value is being passed to the server at 192.168.1.70 as per the schedule I mentioned above. You can use Python requests library to replicate the server communication while you can retain the scheduler for calling the python program to run it as per the same schedule.

Answer 2

It seems to be cron job that runs given command automatically on the given interval: "At minute 1 past every hour from 17 through 23."
Similar Python code would be
import requests
requests.put(
"http://192.168.1.70:80/api/v2/configurations",
data={"EM_OperatingMode":10},
headers={"Auth-Token":"512532eb-0d57-4a59-8da0-e1e136945ee8"}
)

Answer 3

It is crontab, example:
* * * * * Command_to_execute
| | | | |
| | | | Day of the Week ( 0 - 6 ) ( Sunday = 0 )
| | | |
| | | Month ( 1 - 12 )
| | |
| | Day of Month ( 1 - 31 )
| |
| Hour ( 0 - 23 )
|
Min ( 0 - 59 )

And second part is curl with some options (flags): https://curl.se/docs/manpage.html
