需要幫助來追蹤轉換錯誤

Question

我知道這可能有點令人困惑，但我是Python的新手。我有一個學校項目的任務是創建一個二進制到二進制的轉換器，該轉換器可以使用高達255和高達8位的二進制文件。

我基本上把輸入，分割，檢查，把它放到一個列表中，解決它，把它放到另一個列表並打印完成列表。除了最後一部分 - 轉換之外，它都有效。提前致謝。

我得到兩次轉換此錯誤：

Traceback (most recent call last): 
    File "C:\Users\massi_000\Desktop\COM\Task 1 #2.5.py", line 101, in <module> 
    main() 
    File "C:\Users\massi_000\Desktop\COM\Task 1 #2.5.py", line 91, in main 
    checkUp(noToConvert, mainOp) 
    File "C:\Users\massi_000\Desktop\COM\Task 1 #2.5.py", line 80, in checkUp 
    binaryToDenary(noToConvert) 
    File "C:\Users\massi_000\Desktop\COM\Task 1 #2.5.py", line 30, in binaryToDenary 
    while int(doneListBin[int(r)]) > 1: 
    IndexError: list index out of range 

這是我的全部代碼。

doneListBin = [] 
doneListDen = [] 
splitList = [] 
doneList = [] 


def denaryToBinary(splitList): 
    #Works binary 
    for r in splitList: 
     doneListDen.append(int(splitList[int(r)]) % 2) 
     while int(doneListDen[int(r)]) > 1: 
      doneListDen.append(int(splitList[int(r)]) % 2) 
    print(doneListDen) 

def binaryToDenary(splitList): 
    #Works denary 
    for r in splitList: 
     doneListBin.append(int(splitList[int(r)]) * 2 ** (int(r) + 1)) 
     while int(doneListBin[int(r)]) > 1: 
      doneListBin.append(int(doneListBin[int(r)]) * 2 ** (int(r) + 1)) 
    print(doneListBin) 

無一不精當初這裏

def checkUp(noToConvert, mainOp): 
    try: 
     if int(noToConvert) < 0: 
      raise ValueError 

     elif noToConvert.isdigit() == False: 
      raise ValueError 

     elif mainOp == 'd': 
      if int(noToConvert) > 255: 
       raise ValueError 

      else: 
       #Splits input for checking & passes 
       splitList.extend(noToConvert) 
       print(splitList) 
       denaryToBinary(noToConvert) 


     elif mainOp == 'b': 


      #Makes sure it's not huge 
      if int(len(str(noToConvert))) > 8: 
       raise ValueError 

      #Splits input for checking 
      splitList.extend(noToConvert) 
      print(splitList) 

      #Makes it 8-bit 
      if int(len(noToConvert)) < 8: 
       for i in range(8 - int(len(noToConvert))): 
        splitList.insert(0, 0) 
      #while int(len(str(splitList))) < 8: 
      # splitList.insert(0, 0) 
       # print(splitList) 


      #Should only accept valid inputs (0s and 1s) 
      for i in splitList: 
       if int(splitList[int(i)]) == 0 or int(splitList[int(i)]) == 1: 
        print(str(i) + ' in range') 

       else: 
        raise ValueError 
      binaryToDenary(noToConvert) 
    except ValueError: 
     main() 


def main(): 
    ###  CHOICES  ### 
    mainOp = input("Do you want to convert from (D)enary or from (B)inary?: ").lower() 
    noToConvert = input("What is the number to convert?: ") 

    if mainOp in ("d", "denary", "b", "binary"): 
     checkUp(noToConvert, mainOp) 


    else: 
     raise ValueError 



     # EXECUTION # 
main() 

Answer 1

您可以嘗試

def binaryToDenary(splitList): 
    doneListBin = [] 
    for r in range(0, len(splitList)): 
     doneDigit = int(splitList[int(r)]) * 2 ** (len(splitList)-int(r)-1) 
     doneListBin.append(doneDigit) 
    print sum(doneListBin) 

還檢查（noToConvert，mainOp），你應該使用binaryToDenary（splitList），而不是binaryToDenary（noToConvert）

用於二進制的denary

def denaryToBinary(noStr): 
    #Works binary 
    doneListDen = [] 
    noToConvert = int(noStr) 
    while(noToConvert>0): 
     doneListDen.append(noToConvert%2) 
     noToConvert = noToConvert // 2 
    doneListDen.reverse() 
    print doneListDen
