I$$m trying to implement a function $($list$\_$weather$\_$violations$)$ but I$$m struggling with the check the weather portion. Here is the outline of the function we$$re supposed to write and all the helper functions that go with it$.$ I have my code on there, but it$$s not passing the check $$ it$$s giving me an error for the line $$if start$\_$time.date$().$isoformat$()==$ date:$.$ If you have any advice on how to make this code function properly, I$$d greatly appreciate it$!$ I$$m going to include all of the helper functions so you can see what tools I$$m working with. I know they work correctly because they$$ve already been graded.

What I$$m trying to code:

def list$\_$weather$\_$violations$($directory$)$:

$"""$

Returns the $($annotated$)$ list of flight reservations that violate weather minimums.

This function reads the data files in the given directory $($the data files are all

identified by the constants defined above in this module$).$ It loops through the

list of flight lessons $($in lessons.csv$),$ identifying those takeoffs for which

get$\_$weather$\_$violation$()$ is not the empty string.

This function returns a list that contains a copy of each violating lesson, together

with the violation appended to the lesson.

Example: Suppose that the lessons

S$00687548$QR I$0612017-01-08$T$14$:$00$:$00-05$:$002017-01-08$T$16$:$00$:$00-05$:$00$ VFR Pattern

S$00758548$QR I$0722017-01-08$T$09$:$00$:$00-05$:$002017-01-08$T$11$:$00$:$00-05$:$00$ VFR Pattern

S$00971426$JQ I$0722017-01-12$T$13$:$00$:$00-05$:$002017-01-12$T$15$:$00$:$00-05$:$00$ VFR Pattern

violate for reasons of 'Winds', 'Visibility', and 'Ceiling', respectively $($and are the

only violations$).$ Then this function will return the $2$d list

$[[$S$00687,548$QR$,$ I$061,2017-01-08$T$14$:$00$:$00-05$:$00,2017-01-08$T$16$:$00$:$00-05$:$00,$ VFR$,$ Pattern, Winds$],$

$[$S$00758,548$QR$,$ I$072,2017-01-08$T$09$:$00$:$00-05$:$00,2017-01-08$T$11$:$00$:$00-05$:$00,$ VFR$,$ Pattern, Visibility$],$

$[$S$00971,426$JQ$,$ I$072,2017-01-12$T$13$:$00$:$00-05$:$00,2017-01-12$T$15$:$00$:$00-05$:$00,$ VFR$,$ Pattern, Ceiling$]]$

REMEMBER: VFR flights are subject to minimums with VMC in the row while IFR flights

are subject to minimums with IMC in the row. The examples above are all VFR flights.

If we changed the second lesson to

S$00758,548$QR$,$ I$072,2017-01-08$T$09$:$00$:$00-05$:$00,2017-01-08$T$11$:$00$:$00-05$:$00,$ IFR, Pattern

then it is possible it is no longer a visibility violation because it is subject to

a different set of minimums.

Parameter directory: The directory of files to audit

Precondition: directory is the name of a directory containing the files 'daycycle.json',

'weather.json', 'minimums.csv$\text{'},$ 'students.csv$\text{'},$ and 'lessons.csv$\text{'}$

$"""$

# Load in all of the files

# For each of the lessons

# Get the takeoff time

# Get the pilot credentials

# Get the pilot minimums

# Get the weather conditions

# Check for a violation and add to result if so

DAYCYCLE $=$ utils.read$\_$json$($os$.$path.join$($directory$,$"daycycle.json"$))$

WEATHER $=$ utils.read$\_$json$($os$.$path.join$($directory$,$"weather.json"$))$

STUDENTS $=$ utils.read$\_$csv$($os$.$path.join$($directory$,$"students.csv$"))$

MINIMUMS $=$ utils.read$\_$csv$($os$.$path.join$($directory$,$"minimums.csv$"))$

LESSONS $=$ utils.read$\_$csv$($os$.$path.join$($directory$,$"lessons.csv$"))$

result $=[]$

for lesson in LESSONS:

lesson$\_$id$,$ aircraft$\_$id$,$ pilot$\_$id$,$ start$\_$time$\_$str$,$ end$\_$time$\_$str$,$ flight$\_$type, flight$\_$pattern $=$ lesson

start$\_$time $=$ utils.str$\_$to$\_$time$($start$\_$time$\_$str$)$

end$\_$time $=$ utils.str$\_$to$\_$time$($end$\_$time$\_$str$)$

pilot$\_$min $=$ None

for row in MINIMUMS:

if row$[0]==$ pilot$\_$id:

pilot$\_$min $=$ row

break

weather$\_$conditions $=$ None

for date, conditions in WEATHER.items$()$:

if start$\_$time.date$().$isoformat$()==$ date:

weather$\_$conditions $=$ conditions

break

violation $=$ get$\_$weather$\_$violation$($weather$\_$conditions, pilot$\_$min$)$

if violation:

result.append$($lesson $+[$violation$])$

return result

Helper functions I have available:

def get$\_$weather$\_$violation$($weather$,$minimums$)$:

$"""$

Returns a string representing the type of weather violation $($empty string if flight is ok$)$

def get$\_$weather$\_$report$($takeoff$,$weather$)$:

$"""$

Returns the most recent weather report at or before take$-$off.

def read$\_$csv$($filename$)$:

$"""$

Returns the contents read from the CSV file filename.

def write$\_$csv$($data$,$filename$)$:

$"""$

Writes the given data out as a CSV file filename.

def read$\_$json$($filename$)$:

$"""$

Returns the contents read from the JSON file filename.

def str$\_$to$\_$time$($timestamp$,$tzsource$=$None$)$:

$"""$

Returns the datetime object for the given timestamp $($or None if timestamp is

invalid$).$

You have now reached the last function in the module and the hardest
