我該如何修復這個貨幣轉換器的Python？

Question

我已經爲貨幣轉換器製作了這個代碼，但它提供了語法。請我使用python 3.3.2。

currencynum = 0 
yenpound=0.0059 
yendoler=0.0098 
yeneuro=0.0071 
yenyen=1 
yeneuro=0.0071 
yenyen=1 
poundyen=170.55 
pounddoler=1.67 
poundeuro=1.21 
poundpound=1 
dolpound=0.60 
doleuro=0.73 
doldol=1 
dolyen=102.37 
europound=0.83 
eurodol=1.38 
euroyen=140.79 
euroeuro=1 


tipe= input ("input what curontsy you have. yen y,us dollrus d, euro e, pound p.") 
      if tipe == "y": 
       print ("you have choson yen") 

      elif tipe == "e": 
       print("you have choson euro") 

      elif tipe == "d": 
       print ("you have choson us dollrus") 

      elif tipe == "p": 
       print ("you have choson pound") 

      howmuch = float(input("how much do you have")) 

      otheramount = input ("input what curontsy you want to convert. yen y,us dollrus, euro e, pound p.") 

      if otheramount == "y": 
       print ("you have choson yen") 
      elif otheramount == "e":

      #currency = tipe + otheramount 

      #command=currency 
      #total= howmuch * currencynum 
      #print (total)

你的問題似乎是從壞的壓痕.. 你需要大約4個空格（不知道這是版本有關，有時需要6〜8）每個壓痕，然後它會工作。 請記住，每個新的if語句都需要另一個縮進，並且您的乘法應該放在if塊中，因此它也必須縮進！
