Write a function visit_length (visit) to determine the length of a person's visit to a particular location.The function takes one argument, visit, which is a 7-tuple formatted as described above.The function should return the length of the visit as a tuple of integer values, corresponding to hours and minutes if the visit is valid, or None if the visit is not valid. A valid visit is onewith a positive length (ie, more than zero minutes).For example,visit_length ( ("Irene", "Skylabs", 3, 9, 15, 13, 45))|(4, 30)which means that Irene spent 4 hours and 30 minutes at Skylabs from 9:15am to 1:45pm on the third day of the outbreak.Assumptions:• You can assume that the input arguments are syntactically correct given the definitions and assumptions on the previous slides.Here are some example calls to the function: print (visit_length(('Russel', 'Foodigm', 2, 9, 0, 10, 0)))(1, 0) print (visit_length(('Natalya', 'Foodigm', 2, 9, 30, 9, 45)))(0, 15) print(visit_length(('Chihiro', 'Foodigm', 2, 8, 45, 9, 15)))(0, 30) print (visit_length(('Aravinda', 'Afforage', 2, 9, e, 10, 0)))(1, 0) print (visit_length(('Chihiro', 'Foodigm', 2, 8, 30, 9, 0)))(0, 30) print (visit_length(('Natalya', 'Afforage', 2, 15, 10, 14, 45)))# the length of the visit is negativeNone print (visit_length(('Aravinda', 'Nutrity', 2, 15, 10, 15, 10)))# the length of the visit is zeroNone Each visit by a person to a location results in the following data being generated when they scana QR code with their phone:• an ID associated with that person• an ID associated with the location• an integer value corresponding to the day (note that this is not a calendar date, but ratherincrements from "day zero" of the outbreak)• a pair of integer values, corresponding to the time (hours and minutes, in 24 hour time)that the person arrived at the location• a pair of integer values corresponding to the time (hours and minutes, in 24 hour time)that the person departed from the locationIn this project, we will represent this data in a 7-tuple.

The two valuescorresponding to hours (indices 3 and 5) will be in the range [0, 23], and the two valuescorresponding to minutes (indices 4 and 6) will be in the range [0, 59]. Please note: 2am isrecorded as 2 rather than 02, and 5 minutes is recorded as 5 rather than 05.You may assume that all visits are syntactically valid and that no visits for a single person areoverlapping in time, although a successive visits may end and start at the same time
