In this programming task, you'll write a simple Python script to read a file a process the

data contained in the file.

Throughout the programming aspect of the unit, numerous files will be provided, each

requiring a different method of interpretation. As an introduction to the unit, you will be

required to write a program that can parse a simple text file of the following format:

Where each segment of information is delimited by a single space. The columns represent

the following information:

The city to travel from

The city to travel to

The actual distance between the cities $(-1$ indicates direct driving between the

cities is not possible$)$

The straight$-$line distance to the destination

Information about each pair of cities should be read in and parsed and stored in

appropriate data structures. In particular, a Python dictionary should be created so that the

key is a city name $($e$.$g$.,$ 'Melbourne'$)$ and the value is a list of cities whose information

can be extracted from the input text file $-$ e$.$g$.,[(\text{'}$Sydney$\text{'},878,713),(\text{'}$Brisbane$\text{'},-1,$

$].$

this is the starter code

import sys

print$(\text{'}$Number of arguments:$\text{'},$ len$($sys$.$argv$),$ 'arguments.$\text{'})$

print$(\text{'}$Argument List:$\text{'},$ str$($sys$.$argv$[1$:$]))$

filename $=$ sys$.$argv$[0]$

country$\_$map $=\{\}$

with open$($filename$)$ as f:

for line in f:

content$\_$list $=$ line.strip$().$split$("")$

city$1=$ content$\_$list$[0]$

city$2=$ content$\_$list$[1]$

drivingD $=$ content$\_$list$[2]$

straightD $=$ content$\_$list$[3]$

if country$\_$map.get$($city$1)$:

city$1\_$list $=$ country$\_$map.get$($city$1)$

city$1\_$list.append$(($city$2,$ int$($drivingD$),$ int$($straightD$)))$

country$\_$map$[$city$1]=$ city$1\_$list

else:

country$\_$map$[$city$1]=[($city$2,$ int$($drivingD$),$ int$($straightD$))]$

if country$\_$map.get$($city$2)$:

city$2\_$list $=$ country$\_$map.get$($city$2)$

city$2\_$list.append$(($city$1,$ int$($drivingD$),$ int$($straightD$)))$

country$\_$map$[$city$2]=$ city$2\_$list

else:

country$\_$map$[$city$2]=[($city$1,$ int$($drivingD$),$ int$($straightD$))]$

for city, connections in country$\_$map.items$()$:

for connection in connections:

print$($city$,$ connection$[0],$ connection$[1],$ connection$[2])$
