Filename: ppp$\_2.$py

Write the following function:

$*$ name: filter$\_$line

$*$ parameters: string, list, list

$*$ returns: filtered$/$smaller version of second list

Given...

$-$ the name of an MBTA line $($green$,$ orange, red, etc.$)$

$-$ a list of MBTA lines $($green line, orange line, etc.$)$

$-$ a second list that corresponds with the first $($same size$)$

Return...

$-$ a filtered version of the second list.

For example, given:

"green", $["$green line", "red line", "green line"$],[3,4,5]$

Your function should return a filtered version of the second list,

wherever "green" was found in the first:

$[3,5]$

Because the file we're working with uses different names for the lines,

your function should be able to take in "green" or "Green" and find the

corresponding value "green line" or "Green Line" or "GREEN LINE
