Question

如果我选择2并去#Coin购买或出售，我如何跳过#Bitcoin花费？

#Bittrex Buy and Sell
choice=float(raw_input("Enter 1 Buy, 2 Sell :       "))
if (choice!=1):
    if (choice!=2): 
        sys.exit('Choice number {0} not valid. Please enter 1 to Buy or 2 to Sell'.format(choice))

#Bitcoin to spend
bitcoin=float(raw_input("Bitcoin to Spend: "))

#Market to trade at
trade = 'BTC'

#Coint to Buy
currency = raw_input("Coin: ")

Answer 1

虽然我不是这样做的，但这是一种更清洁的方式来处理你追求的方法。

#Bittrex Buy and Sell
choice=float(raw_input("Enter 1 Buy, 2 Sell :       "))
if choice not in [1,2]:
    sys.exit('Choice number {0} not valid. Please enter 1 to Buy or 2 to Sell'.format(choice))

if choice == 1:
    #Bitcoin to spend
    bitcoin=float(raw_input("Bitcoin to Spend: "))

if choice == 2:
    #Coint to Buy
    currency = raw_input("Coin: ")

#Market to trade at
trade = 'BTC'
