python - if 语句中的 if 语句

Question

这是我的功课，我坚持让代码成为后续问题，就像这里的这段代码，我试过在那之后插入一个 if 语句，但它给了我一个意外的激励错误。

到目前为止，这是我的代码:

Choice = input("Hello! Do you want to buy or sell snakes? Please enter (b) or (s) :")
if Choice == "b":
    buySnake = input ("What snake do you want to buy? We are selling python, kingsnake, rattlesnake, deathadder, cobra, mamba, viper and gartersnake. Please choose one : ")
        if buySnake == "python":
             return (to be added)   
elif Choice == "s":
    sellFsnakes(snakeList,name,amount)
else:
    print("Please try again.")
    buyWsnakes(snakeList,name,amount)

Answer 1

你有一个额外的缩进。只需删除额外的缩进级别:

Choice = input("Hello! Do you want to buy or sell snakes? Please enter (b) or (s) :")
if Choice == "b":
    buySnake = input ("What snake do you want to buy? We are selling python, kingsnake, rattlesnake, deathadder, cobra, mamba, viper and gartersnake. Please choose one : ")
    if buySnake == "python":
        return (to be added)   
elif Choice == "s":
    sellFsnakes(snakeList,name,amount)
else:
    print("Please try again.")
    buyWsnakes(snakeList,name,amount)
