from currency_converter import CurrencyConverter
エラーを修正するために金額をグローバル化しようとしましたが、役に立ちませんでした
global amounts
c = CurrencyConverter()
currency = input('What ?')
currency = currency.split()
選択する通貨のリスト、辞書
currencys = {"pounds":"GBP" , "dollars":"USD" , "euros":"EUR"}
WCurrency = ' '
これは、文が何であるかを認識する場所です
if 'what' in currency:
next_word = currency[currency.index('what') + 1]
if next_word == 'is':
可能であれば短縮したいステートメントの場合は長い
if 'pounds' in currency:
amounts = currency[currency.index('pounds') - 1]
WCurrency = currencys['pounds']
if 'euros' in currency:
amounts = currency[currency.index('euros') - 1]
WCurrency = currencys['euros']
if 'dollars' in currency:
amounts = currency[currency.index('dollars') - 1]
WCurrency = currencys['dollars']
if 'in' in currency:
next_word = currency[currency.index('in') + 1]
if next_word == 'dollars':
W2Currency = currencys['dollars']
if next_word == 'pounds':
W2Currency = currencys['pounds']
if next_word == 'euros':
W2Currency = currencys['euros']
これにより、別の形式で文を入力できます
if 'how' in currency:
next_word = currency[currency.index('how') + 1]
if next_word == 'many':
可能であれば短縮したいステートメントの場合は長い
if 'pounds' in currency:
W2Currency = currencys['pounds']
if 'euros' in currency:
W2Currency = currencys['euros']
if 'dollars' in currency:
W2Currency = currencys['dollars']
if 'is' in currency:
next_word = currency[currency.index('is') + 1]
if next_word == 'dollars':
amounts = currency[currency.index('dollars') - 1]
WCurrency = currencys['dollars']
if next_word == 'pounds':
amounts = currency[currency.index('pounds') - 1]
WCurrency = currencys['pounds']
if next_word == 'euros':
amounts = currency[currency.index('euros') - 1]
WCurrency = currencys['euros']
def convertCurrency(amount, currency, targertCurrency):
try:
return c.convert(amount , currency , targertCurrency)
except:
print('Invalid currency or amounts!')
print(convertCurrency(amounts, str(WCurrency), str(W2Currency)))
elifこれを使用すると、ドルが再び認識されるのを防ぎます。また、それは良い習慣です。すなわち。
if 'pounds' in currency:
amounts = currency[currency.index('pounds') - 1]
WCurrency = currencys['pounds']
elif 'euros' in currency:
amounts = currency[currency.index('euros') - 1]
WCurrency = currencys['euros']
elif 'dollars' in currency:
amounts = currency[currency.index('dollars') - 1]
WCurrency = currencys['dollars']
elif 'in' in currency:
next_word = currency[currency.index('in') + 1]
elif next_word == 'dollars':
W2Currency = currencys['dollars']
elif next_word == 'pounds':
W2Currency = currencys['pounds']
elif next_word == 'euros':
W2Currency = currencys['euros']
これは、dollarsとpoundsがセンテンスにある場合、最初のものを認識することを意味します。残念ながら、このコードは非常に面倒なので、forループを使用することをお勧めします。すなわち。
for word in sentance:
if word is in [list, of, currencies] and isdigit(sentance(word.index() - 1)):
currency = word
等々...
