  1. You can see the output in the terminal.

Explanation

  1. First, we have imported the required modules. We have imported the requestsrequests module and BeautifulSoupBeautifulSoup module. We have imported the requestsrequests module to request the URL and the BeautifulSoupBeautifulSoup module to parse the HTML.
currencyconverter.py
import requests
from bs4 import BeautifulSoup
currencyconverter.py
import requests
from bs4 import BeautifulSoup
  1. Then we have created a variable named urlurl and assigned the URL to it. We have used %s%s to add the variables in the URL.
currencyconverter.py
url = "https://www.x-rates.com/calculator/?from=%s&to=%s&amount=%s"
currencyconverter.py
url = "https://www.x-rates.com/calculator/?from=%s&to=%s&amount=%s"
  1. Then we have printed the list of currencies. We have used the print()print() function to print the list of currencies.
currencyconverter.py
print("Currency Converter")
print('''

        1. USD - US Dollar
        2. EUR - Euro

        5. AUD - Australian Dollar
        6. CAD - Canadian Dollar
        7. SGD - Singapore Dollar
        8. CHF - Swiss Franc
        9. MYR - Malaysian Ringgit
        10. JPY - Japanese Yen
        11. CNY - Chinese Yuan Renminbi
        12. NZD - New Zealand Dollar
        13. THB - Thai Baht
        14. HUF - Hungarian Forint
        15. AED - Emirati Dirham
        16. HKD - Hong Kong Dollar
        17. MXN - Mexican Peso
        18. ZAR - South African Rand
        19. PHP - Philippine Peso
        20. SEK - Swedish Krona
        
        Don't Enter the Number. Enter the currency code.
    ''')
currencyconverter.py
print("Currency Converter")
print('''

        5. AUD - Australian Dollar

        17. MXN - Mexican Peso
        18. ZAR - South African Rand
        19. PHP - Philippine Peso
        20. SEK - Swedish Krona
        
        Don't Enter the Number. Enter the currency code.
    ''')
  1. Then we have used the input()input() function to get the user input. We have used the upper()upper() function to convert the user input to uppercase. We have used the input()input() function to get the user input. We have used the upper()upper() function to convert the user input to uppercase.
currencyconverter.py
from_currency = input("From Currency: ").upper()
to_currency = input("To Currency: ").upper()
amount = input("Amount: ")
currencyconverter.py
from_currency = input("From Currency: ").upper()
to_currency = input("To Currency: ").upper()
amount = input("Amount: ")
  1. Then we have requested the URL. We have used the get()get() function to request the URL. We have used the find()find() function to find the converted amount. We have used the texttext attribute to get the text from the HTML. We have used the find()find() function to find the converted amount. We have used the texttext attribute to get the text from the HTML.
currencyconverter.py
response = requests.get(url % (from_currency, to_currency, amount))
soup = BeautifulSoup(response.text, "html.parser")
converted_amount = soup.find("span", class_="ccOutputRslt").text
currencyconverter.py
response = requests.get(url % (from_currency, to_currency, amount))
soup = BeautifulSoup(response.text, "html.parser")
converted_amount = soup.find("span", class_="ccOutputRslt").text
  1. Then we have printed the converted amount. We have used the print()print() function to print the converted amount.
currencyconverter.py
print(f'{amount} {from_currency} = {converted_amount}')
currencyconverter.py
print(f'{amount} {from_currency} = {converted_amount}')
