Need help with a python assignment

Here is the task.py I currently have:

class Task:

$"""$Shows the format for each file

Attributes:

desc $($str$)$: description of the task

date $($str$)$: due date of the task $($formatted in MM$/$DD$/$YYYY$)$

time $($str$)$: time the task is due $($formatted in HH:MM$)$

$"""$

def $\_\_$init$\_\_($self$,$ desc, date, time$)$:

self.description $=$ desc

self.date $=$ date

self.time $=$ time

def get$\_$description$($self$)$:

return self.description

def $\_\_$str$\_\_($self$)$:

return f$"\{$self$.$description$\}-$ Due: $\{$self$.$date$\}$ at $\{$self$.$time$\}"$

def $\_\_$repr$\_\_($self$)$:

return f$"\{$self$.$description$\},\{$self$.$date$\},\{$self$.$time$\}"$

def $\_\_$lt$\_\_($self$,$ other$)$:

self$\_$date$\_$time $=$ f$"\{$self$.$date$\}\{$self$.$time$\}"$
