By Papri Boyra

A currency converter that fetches exchange rates from the Open Exchange Rates API .API functionality use into their applications and streamline data processing.

The requests library is imported to enable HTTP requests to be sent to the API and to retrieve responses. This library is essential for interfacing with RESTful APIs and is commonly used in Python programming. It can be installed through the pip package manager. Sending HTTP requests can be used for various purposes, such as retrieving data, updating information, or performing actions. With this library, developers can easily incorporate API functionality into their applications and streamline data processing.

 The get_exchange_rate function takes two parameters, the base currency and the target currency, and constructs an API URL to retrieve the exchange rate between the two currencies. It then sends a GET request to the API and retrieves the response in JSON format. From the response, the function extracts and returns the exchange rate for the target currency. This function can be useful for financial calculations and currency conversions.

 The convert_currency function is a useful tool for performing currency conversions. It takes in two parameters, the amount to convert and the exchange rate, and returns the converted amount based on the provided exchange rate. This allows users to easily convert between different currencies and get an accurate representation of the value of their money in a foreign currency. Whether for personal or business use, the convert_currency function can simplify the process of converting currencies and make it easier to conduct transactions across international cities. 

This currency converter program prompts the user to input the base and target currency, as well as the amount they would like to convert. It then uses the get_exchange_rate function to fetch the exchange rate, and the convert_currency function to calculate the conversion. The program outputs the converted amount in the target currency. 

The script uses an API to fetch the exchange rate between two currencies. It constructs an API URL with the base and target currencies, sends a GET request, and receives data in JSON format. The script then extracts the exchange rate for the target currency from the API response. This can be useful for anyone who needs to convert currencies for financial or business purposes.
