If you wish to know more about it, you can refer to forex-python Module Documentation.

Now that you are familiar with BitCoin and Currency and have acquired basic knowledge of forex-python module, we can move forward to the coding section.

Time to Code!

You can find all the code at my GitHub Repository. Drop a star if you find it useful.

In order to access the Python library, you need to install it into your Python environment

pip install forex-python

Now, we need to import the package in our python script. Use the following command to do so.

from forex_python.converter import CurrencyCodes, CurrencyRates
from forex_python.bitcoin import BtcConverter

Let's create an instance of CurrencyCodes. I am naming it as test1.

test1 = CurrencyCodes()

Once done, let's fetch the currency symbol. I am making use of get_symbol method for the same and passing the currency code as a parameter. Let's store it in cur_symbol.

cur_symbol = test1.get_symbol('INR')

Let's fetch the currency name. I am making use of get_currency_name method for the same and passing the currency code as a parameter. Let's store it in cur_name.

cur_name = test1.get_currency_name('INR')

Let's display the output.

print('The currency name is: ' + cur_name)
print('The currency symbol is: ' + cur_symbol)

#let's see for another example
print('\n' + test1.get_symbol('USD'))
print(test1.get_currency_name('USD'))

#OUTPUT:
The currency name is: Indian rupee
The currency symbol is: ₹

US$
United States dollar

Now, let's move forward and create an instance for CurrencyRates.

test2 = CurrencyRates()

Once done, let's fetch the Conversion rate. I will make use of get_rate method for the same. Let's fetch what 1 United States Dollar equals-to in Indian rupee.

rate = test2.get_rate('USD', 'INR')
print(rate)

#OUTPUT:
73.6702434998

Now that we have successfully fetched the conversion rate, let's try converting 10 US$ to Indian rupee. I will make use of convert method for the same.

res = test2.convert('USD', 'INR', 10)
print(res)

#OUTPUT:
736.702434998

I am passing three parameters here,

original currency
the converted currency
conversion amount

BONUS:

Let's fetch BITCOIN's latest price details. Let's start by creating an instance of BtcConverter

bitcoin = BtcConverter()

Now, let's fetch the latest price, I will make use of get_latest_price method for the same. Finally, you can printout the result.

price = bitcoin.get_latest_price('INR')

#display the output
print(price)

With these steps, we have successfully Created Currency Converter using python. That's it!

Simple, isn't it? Hope this tutorial has helped. I would strongly recommend you to Check out the YouTube video of the same and don't forget to subscribe my Channel.
