Write a program that first reads in the name of an input file and then reads the input file using the file.readlines$()$ method. The input file contains an unsorted list of number of seasons followed by the corresponding TV show. Your program should put the contents of the input file into a dictionary where the number of seasons are the keys, and a list of TV shows are the values $($since multiple shows could have the same number of seasons$).$

Sort the dictionary by key $($least to greatest$)$ and output the results to a file named output$\_$keys.txt$,$ separating multiple TV shows associated with the same key with a semicolon $($;$).$ Next, sort the dictionary by values $($alphabetical order$),$ and output the results to a file named output$\_$titles.txt$.$

Ex: If the input is:

file$1.$txt

and the contents of file$1.$txt are:

$20$

Gunsmoke

$30$

The Simpsons

$10$

Will & Grace

$14$

Dallas

$20$

Law & Order

$12$

Murder, She Wrote

the file output$\_$keys.txt should contain:

$10$: Will & Grace

$12$: Murder, She Wrote

$14$: Dallas

$20$: Gunsmoke; Law & Order

$30$: The Simpsons

and the file output$\_$titles.txt should contain:

Dallas

Gunsmoke

Law & Order

Murder, She Wrote

The Simpsons

Will & Grace

I have this so far and it is so close I just need to get rid of the zeros in front of $7,8,$ and $9$filename $=$ input$()$

f $=$ open$($filename$,\text{'}$r$\text{'})$

data $=$ f$.$readlines$()$

f$.$close$()$

dictionary $=\{\}$

list$\_$of$\_$values $=$ set$()$

for i in range$($len$($data$))$:

data$[$i$]=$ data$[$i$].$strip$()$

for i in range$(0,$ len$($data$),2)$:

key $=$ data$[$i$]$

value $=$ data$[$i$+1]$

if key in dictionary:

if value not in dictionary$[$key$]$:

dictionary$[$key$]+=\text{'}$; $\text{'}+$ value

list$\_$of$\_$values.add$($value$)$

else:

dictionary$[$key$]=$ value

list$\_$of$\_$values.add$($value$)$
