currency_converter

Entry task to PythonMaster. This is my first Python script ever (not counting Codecademy curses).

##Usage

./currency_converter.py -h
usage: currency_converter.py [-h] --amount AMOUNT --input_currency
                             INPUT_CURRENCY
                             [--output_currency OUTPUT_CURRENCY]

This is a converter for currencies. For available currencies check
http://api.fixer.io/latest

optional arguments:
  -h, --help            show this help message and exit
  --amount AMOUNT       Amount which you want to convert
  --input_currency INPUT_CURRENCY
                        Input currency: 3 letters name or currency symbol,
                        e.g. USD, EUR, $, €
  --output_currency OUTPUT_CURRENCY
                        Requested currency: same format as Input currency.
                        Omit to convert to all known currencies
