Complete the function parse$\_$file$().$ This function takes a file name as a parameter, reads the file line by line and

creates a data structure to represent the input. The structure has the following format: at the $$top$$ it is a pair. The

first element of the pair is a list of names $($the participants$)$ in the order given in the file. The second element of the

pair is a list of pairs; each list cell will correspond to a given day.

Within each list$-$pair, the first element should be a dictionary whose keys are the names of those tested for vampirism

and whose values are the Booleans True $($that is$,$ a vampire, indicated by $$V$$ in the input file$)$ or False $($that is$,$ a

human$).$ The second element of a list$-$pair is a list of lists, with each $$outer$$ list$-$element being an $$inner$$ list of those

groups who were in contact on that day. After you finish processing the file, make sure to close it$,$ and then return

the structure you$$ve created. Here$$s the structure we$$d expect for the sample file given above, as printed by Python:

$([\text{'}$Bella$\text{'},$ 'Edward', 'Jacob', 'Carlisle', 'Alice', 'Emmett', 'Charlie',

'Renee', 'Jessica', 'Angela'$],[(\{\text{'}$Edward$\text{'}$: True, 'Bella': False, 'Jacob':

False, 'Jessica': False$\},[[\text{'}$Bella$\text{'},$ 'Edward'$],[\text{'}$Charlie$\text{'},$ 'Jacob'$],$

$[\text{'}$Alice$\text{'},$ 'Renee'$]]),(\{\text{'}$Bella$\text{'}$: False, 'Jacob': False, 'Alice': True,

'Charlie': False$\},[[\text{'}$Bella$\text{'},$ 'Edward', 'Charlie'$],[\text{'}$Angela$\text{'},$ 'Jessica'$]]),$

$(\{\text{'}$Emmett$\text{'}$: True, 'Renee': False, 'Jessica': True$\},[]),(\{\text{'}$Bella$\text{'}$: True,

'Charlie': False$\},[[\text{'}$Bella$\text{'},$ 'Edward', 'Charlie', 'Jessica', 'Angela'$],$

$[\text{'}$Jacob$\text{'},$

'Renee'$]])])$

If the file isn$$t somehow formatted correctly $$ for example, if one of the numbers isn$$t a number when you convert it

to an integer $$ then print the error message
