追加數據到字典

Question

我讀file.txt的，這下面的數據：

 Arjun 10th 20  88+ 

     +  77 76  36   

如何使類作爲重點，並添加其他值對應key.which看起來像 {「10」 ：['20'，[88,77,76,36]]}

注意：行中的值以+符號結尾，下一行以+符號開頭，我們如何將它們插入到同一個列表中？

儘管這個問題沒有得到很好的解釋，但我認爲你所要做的就是這樣。請檢查功能words，並告訴我這是或多或少在正確的方向。

def words(d, auxList): 
    # Variables to save state between lines 
    curKey = None 
    values = [] 

    for line in auxList: 
     items = line.split() 
     # Check if we have values already from a previous line 
     if curKey is None: 
      # Check if we see a continuation symbol (+) 
      if items[-1][-1] == '+': 
       # and remove it from the value 
       items[-1] = items[-1][:-1] 
       # Save the info in this line 
       curKey = items[1] 
       values = items[2:] 
      else: 
       # If all the information is in one simple line 
       d[items[1]] = items[2:] 
     else: 
      # Check if we see a continuation symbol (+) 
      if items[-1][-1] == '+': 
       # and remove it from the value 
       items[-1] = items[-1][:-2] 
       # Save the info in this line and accumulate it 
       # with the previous ones 
       values.extend(items[1:]) 
      else: 
       # Update dictionary when we have all the values 
       d[curKey] = values + items[1:] 
       # and reset state 
       curKey = None 
       values = [] 

    # Be sure to save the last line if there is no more info 
    # Maybe it is not necessary 
    if curKey is not None: 
     d[curKey] = values 


d = {} 
a2 = [line.strip() for line in myfile.readlines()] 
words(d, a2)
