Question

develop a real time currency converter with GUI using python

Answer 1

# import all functions from the tkinter

from tkinter import *

 

# Create a GUI window

root = Tk()

 

# create a global variables

variable1 = StringVar(root)

variable2 = StringVar(root)

 

# initialise the variables

variable1.set("currency")

variable2.set("currency")

 

     

# Function to perform real time conversion

# from one currency to another currency

def RealTimeCurrencyConversion():

 

    # importing required libraries

    import requests, json

 

    # currency code

    from_currency = variable1.get()

    to_currency = variable2.get()

 

    # enter your api key here

    api_key = "Your_Api_Key"

     

    # base_url variable store base url

    base_url = r"https://www.alphavantage.co/query?function = CURRENCY_EXCHANGE_RATE"

 

    # main_url variable store complete url

    main_url = base_url + "&from_currency =" + from_currency +

        "&to_currency =" + to_currency + "&apikey =" + api_key

 

    # get method of requests module

    # return response object

    req_ob = requests.get(main_url)

 

    # json method return json format

    # data into python dictionary data type.

     

    # result contains list of nested dictionaries

    result = req_ob.json()

 

    # parsing the required information

    Exchange_Rate = float(result["Realtime Currency Exchange Rate"]

                                              ['5. Exchange Rate'])

 

    # get method of Entry widget

    # returns current text  as a

    # string from text entry box.

    amount = float(Amount1_field.get())

 

    # calculation for the conversion

    new_amount = round(amount * Exchange_Rate, 3)

 

    # insert method inserting the

    # value in the text entry box.

    Amount2_field.insert(0, str(new_amount))

 

 

# Function for clearing the Entry field

    # Start the GUI

    root.mainloop()
