Python的 - 字符串分割線

Question

add_numbers("A1", "Element 560234 65952 6598881 20203256 2165883 659562 654981 24120 261240 31648948 23900 5512400 5512900 5612400 5612900") 

add_numbers("A2", "Element 261240 31659 5612400 76803256 3165883 659863 654224 44120 261240 31648948 23900 3612200 9512900 5612400 5642924") 

add_numbers("A3", "Element 841225 65952 2165883 63103256 2165883 644861 344966 84120 161540 31653948 23900 5513426 5518906 5682405 8682932")

我希望得到一個字典（從上面這是一個txt文件中的字符串），看起來像這樣：

{A1: 560234, 65952,6598881, 20203256,2165883, 659562,....} 

{A2: 261240 31659 5612400,....} 

{A3: 841225 65952 2165883,....}

你有什麼想法？我怎樣才能做到這一點？謝謝。

Answer 1

的理解是，要處理這個

add_numbers("A1", "Element 560234 65952 6598881 20203256 2165883 659562 654981 24120 261240 31648948 23900 5512400 5512900 5612400 5612900") 

add_numbers("A2", "Element 261240 31659 5612400 76803256 3165883 659863 654224 44120 261240 31648948 23900 3612200 9512900 5612400 5642924") 

add_numbers("A3", "Element 841225 65952 2165883 63103256 2165883 644861 344966 84120 161540 31653948 23900 5513426 5518906 5682405 8682932") 

爲文本文件的文字內容轉換成字典，我會做這樣的：

import re // import regular expression module 
d = {} 

for line in open("myfile.txt", "r"): 
    if not line.strip(): continue  // Skip blank lines 
    data = re.findall('"([^"]*)"', line) // Extract text between double quotes 

    if len(data) != 2: continue   // There were not exactly two pairs of double quotes, skip this line 

    key, value = data 
    d[key] = map(int, value.split()[1:]) // Remove "Element" and convert numbers to integers, add to dictionary 

An expl正則表達式"([^"]*)"的anation：

• "()"引號
• [^"]*的0或多個字符的字符串，是不是"

re.findall將顯示在列表中返回結果裏面的東西匹配。

編輯

I get an error. ValueError: need more than 1 value to unpack

您必須不包含在文件中的兩個對雙引號的線。我更新了上面的代碼以忽略不符合您的規範的行。

Answer 2

import re,ast 
def add_numbers(d,key,elements): #we pass in a reference to a dict, which we update 
    d[key] = map(int,elements.split()[1:]) #Returns ["Element",...], so we select all but first [1:] 
dic = {} 
with open('file.txt') as f: 
    for line in f: 
     key,elems = ast.literal_eval(re.search(r'\((.+)\)',line).group(0)) 
     add_numbers(dic,key,elems) 

現在生產
