$15.$ Implement ratings$/$endorsements $($OPTIONAL$)$

The next three functions $$ has$\_$instrument$\_$rating, has$\_$advanced$\_$endorsement, has$\_$multiengine$\_$endorsement $$ are completely optional. They will be used later by some sections of the project that are optional. You can code them now or you can choose to skip these for now and circle back to them later if you decide to work on the optional sections that depend on them. These functions are not necessary to complete this part of the project, and they will not be checked on submission. You can even work on this part of the project after the course is over, provided you copy these instructions.

These functions have to do with ratings $($what conditions the pilot can fly in$)$ and endorsements $($what types of planes the pilot can fly$).$ These are extremely short functions and can be computed in two or three lines. You simply need to look at the take$-$off time and compare it to the appropriate column for the student. As a reminder, the argument student is not a table of students but a single row of the table.

Implement these functions as specified and run the test script. If you have done everything correctly, you should see the following:

Testing module pilots

pilots.get$\_$certification passed all tests

pilots.has$\_$instrument$\_$rating passed all tests

pilots.has$\_$advanced$\_$endorsement passed all tests

pilots.has$\_$multiengine$\_$endorsement passed all tests

def has$\_$advanced$\_$endorsement$($takeoff$,$student$)$:

$"""$

$($OPTIONAL$)$

Returns True if the student has an endorsement to fly an advanced plane at the time of takeoff.

The function returns False otherwise.

Recall that a student is a $10-$element list of strings. The first three elements are

the student's identifier, last name, and first name. The remaining elements are all

timestamps indicating the following in order: time joining the school, time of first

solo, time of private license, time of $50$ hours certification, time of instrument

rating, time of advanced endorsement, and time of multiengine endorsement.

Parameter takeoff: The takeoff time of this flight

Precondition: takeoff is a datetime object

Parameter student: The student pilot

Precondition: student is $10-$element list of strings representing a pilot

$"""$

pass

def has$\_$multiengine$\_$endorsement$($takeoff$,$student$)$:

$"""$

$($OPTIONAL$)$

Returns True if the student has an endorsement to fly an multiengine plane at the time of takeoff.

The function returns False otherwise.

Recall that a student is a $10-$element list of strings. The first three elements are

the student's identifier, last name, and first name. The remaining elements are all

def get$\_$best$\_$value$($data$,$ index, maximum$=$True$)$:

$"""$

Returns the 'best' value from a given column in a $2-$dimensional nested list.

This function is a helper function for get$\_$minimums $($whose docstring you should

read and understand first$).$

The data parameter is a $2-$dimensional nested list of data. The index parameter

indicates which "colummn" of data should be evaluated. Each item in that column

is expected to be a number in string format. Each item should be evaluated as a

float and the best value selected as the return value for the function. The

best value is determined by the maximum parameter and is either the highest or

lowest float value.

The $2$D list does not include a header row. It should not be modified in any way.

Parameter data: a $2-$dimensional nested list of data

Precondition: the column referenced by index should by numbers in string format

Parameter index: position to examine in each row of data

Precondition: index is a an integer

Parameter maximum: indicates whether to return the highest value $($True$)$ or

lowest value $($False$)$

Precondition: maximum is a boolean and defaults to True
