Values in date URL

[DrSavage]

Hi
First time here and newbie learning Python, so hope you can help me ?

This is the amended url, which works internally only and will return 5 seconds of data

http://monitoring/dashboards/php/feed/liveviewership.php?graphdata=true&startday=20180415%2007:00&endday=20180415%2007:05

How can I ask the user for the startday and endday values, check its correct date and time format and use the user date/time for checking the data ?

From the data returned I have to put it into fields to look for the min and max and amount of data.

Any help or advice would be very gratefully received

Thanks
