Question

Write a program that reads the data from rawdata_2004.txt into a dictionary whose keys are country names and whose values are per capita incomes. Then the program should prompt the user to enter country names and print the corresponding values. Stop when the user enters quit.

Answer 1

Answer:

import re

def country_capita():

   #opens file

   file=open("inputfile.txt", "r")

   dictionary=dict()

   #reads line by line

   for line in file.readlines():

       # substitutes for multiple space a single space

       line = re.sub(r"[\s]{2, }", ' ', line)

       list=[]

       #splits line on space

       list=line.split(" ")

       #put into dictionary

       dictionary[list[1]]=list[2]

#   get input

   while True:

       choice=input("Enter the country name or quit to exit: ")

       if choice=="quit":

           break

       elif choice in dictionary.keys():

           print(dictionary[choice])

       else:

           print("Invalid Country")

country_capita()

Explanation:

Using python to code this program. First we, (line 1) import the re module which offers us a set of functions that allows us to search a string for a match. ((line 2) Next we define a function country_capita() that will open rawdata_2004.txt, read the information within line by line and create a dictionary list. The we create a while loop with conditional statements that prompt the user to enter country names, print the corresponding values and stops when the user enters quit.
