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.
A micro processor is an integrated circuit that have all the functions of a central processing unit of a computer.
The chip which is thought to be the first microprocessor is INTEL 4004. It was manufactured by Intel in 1971. Intel 4004 has 2,300 transistors.

Answer:
at the end, i.e., after the for loop.
