Currency Process Flow

getCurrency flow is used to get the Currency of a Country. Once getCurrency flow is invoked, Rawspeech is passed to the getCurrency flow to identify the Country Name.

getCountryName parses the RawSpeech against the list of country from pycountry and return the country name identified.

while i<len(pycountry.countries):
    if subStrCheck(rawspeech,(list(pycountry.countries)[i].name)):
        countryname = list(pycountry.countries)[i].name
        break
    i = i+1
    if i == len(pycountry.countries):
        countryname = "India"
