正在讀取文件，將文本行中的單詞和數字添加到字典中？

Question

我正在嘗試編寫一個Python代碼，它可以讓我讀取文本，並按行讀取它的行 。在每行中，單詞作爲關鍵詞進入詞典，數字應該是分配的值，作爲列表。 例如，該文件將被由數百個行具有相同的格式，因爲這的：

彼得17 29 24 284 72

在理想情況下，命名爲「彼得」將是一個關鍵在字典中，值將是dict[Peter]: [17, 19, 24, 284,7273]。

我到目前爲止的問題是添加數字。我不知道如何將它們分配給關鍵值。

def wordDict(filename): 
     inFile=open(filename, 'r') 
     line=inFile.readline() 
     while line: 
      txtWords = line.split() # splits at white space 
      wordScores={} # make dict 
      scoreList=[] 
      for word in txtWords: 
       word.lower() # turns word into lowercase 
       if word in string.ascii_lowercase: #if word is alphabetical 
        if word not in wordScores.keys(): 
         wordScores=wordScores[word] # add the key to dictionary

如果您的線條都與一個字，然後空格分隔的整數開始，你可以做（​​未經測試）：

myDict = {} 
with open('inFile.txt','r') as inFile: 
    for line in inFile: 
     line = line.split() 
     name = line[0].lower() 
     if name not in myDict: 
      myDict[name] = map(int,line[1:])

我還是要強調你的代碼兩個主要問題：

1. for word in string.ascii_lowercase:是一樣的書寫for 'hello' in ['a','b,'c']:，它不會做你所期望的;而循環將永遠不會運行。

2. wordScores = wordScores[word]這不是爲鑰匙添加任何東西，你的意思可能是wordScores[word] = []。

試試這個：

from collections import defauldict 
words = defaultdict(list) 

with open('somefile.txt') as f: 
    for line in f: 
     if line.strip(): 
     bits = line.split() 
     if bits[0].isalpha(): 
      words[bits[0].lower()] += bits[1:]

使用Python 3.2：

with open("d://test.txt", "r") as fi: # Data read from a text file is a string 
    d = {} 
    for i in fi.readlines(): 
     # So you split the line into a list 
     temp = i.split() 
     # So, temp = ['Peter', '17', '29', '24', '284', '72'] 

     # You could split 'temp' like so: 
     # temp[0] would resolve to 'Peter' 
     # temp[1] would resolve to ['17', '29', '24', '284', '72'] 
     name, num = temp[0], temp[1:] 

     # From there, you could make temp[0] the key and temp[1:] the value. 
     # But: notice that the numbers are still represented as strings. 
     # So, we use the built-in function map() to turn them into integers. 
     d[name] = [map(int, num)]
