I'm stuck on what to do next for my PYTHON assignment for class. The program we're suppose to make is to have the user enter a choice, 1-4.

1. Asks the name of a country and displays the currency and exhange rate of said country.

2. Converts currency from one country to another/

3. Displays the country's from A-Z

4. is suppose to sort the country's from the lowest exchange rate to the highest.

f=open('CurrencyExchange02082020.txt') print ('1.View Country, 2. Convert, 3. List all countries in A-Z, 4. List all countries money-wise') choice1=input ('Which operation do you wish to choose? ') if choice1 == "1": country=input('Enter the name of a country: ') country=country.lower() d={} for line in f: line=line.strip() data=line.split(',') if data[0].lower() not in d: d[data[0].lower()]=[data[1],data[2]]

if country: if country in d: print('Currency: ',d[country][0]) print('Exchange rate: ',d[country][1]) else: print('Country not found in the list') else: print('Enter a country name:')

if choice1 == "2": f=open('CurrencyExchange02082020.txt') d={}

for line in f: line=line.strip() data=line.split(',') if data[0].lower() not in d: i=float(data[2]) d[data[0].lower()]=[data[1],i]

country1=input('Enter name of first country: ') country1=country1.lower() country2=input('Enter name of second country: ') country2=country2.lower() amount=int(input('Amount of money to convert: ')) if country1 in d: if country2 in d: exc=d[country1][1] exc2=d[country2][1] mny=d[country1][0] mny2=d[country2][0] amt=amount * (exc2 /exc) print('%d %s from %s equals %.2f %s from %s' %(amount,mny,country1.capitalize(),amt,mny2,country2.capitalize())) else: print('%s is not in the list' %country2) print('Try again') else: print('%s is not in the list' %country1) print('Try again')

if choice1 == "3": file_name = open('CurrencyExchange02082020.txt') new_list = [] for items in file_name: if items != ' ': items = items.replace(" ", "") new_list.append(items) new_list = sorted(new_list) for i in new_list: print (i)

I'm stuck on how to actually do the 4th option. Could someone point me in the right way please?

and here is the .txt file that it reads
