使用Python將個別郵件與郵件路徑分開

我正在使用Python處理與電子郵件相關的PoC。系統收到包含郵件蹤跡的電子郵件。我想從郵件蹤跡中分離出個別電子郵件並處理它們。問題是我沒有得到正確的代碼或庫來做到這一點。任何人都可以請幫忙。使用Python將個別郵件與郵件路徑分開

例如，系統收到電子郵件像下面

上述郵件應該在四個部分被分裂像下面

1）

------ ----- EDITED 經過大量置換，我來用下面的代碼。

startMsgPatter= 
re.compile((\W*ORIGINAL\s*MESSAGE|\W*FROM\s*:|\W*ON.*WROTE\s*:)") 
def sperateEmails(callDesc): 
    itr = startMsgPatter.finditer(callDesc) 
    blockStart = 0 
    emails = [] 

    while True: 
     m = next(itr,None) 
     if not m: 
      break 
     blockEnd = m.start() 
     if blockStart >= blockEnd: 
      continue 
     emailPart = callDesc[blockStart:blockEnd] 
     emails.append(emailPart) 
     blockStart = blockEnd 
     emails.append(callDesc[blockStart:len(callDesc)]) 
    return emails

它正在工作，但我必須繼續查找指示郵件開始和結束的模式並更新它。按照我的說法，這封郵件應該遵循特定的模式。考慮到大多數此類模式，是否有人編寫過代碼，請分享。

你能舉個例子嗎？ – BoilingFire

可以使用函數分裂（）

實施例：

"first mail separator second mail".split(" separator ")

可否outpout：

[ 「第一郵件」，「第二郵件」]

你只需要知道哪個分離rator使用。請注意，分隔符將從結果中刪除，但如果需要它，則可以在之後重新使用它。

在你的情況，似乎所有的消息都是由字符串分隔

"---------------ORIGINAL MESSAGE------------------"

或

"FROM"

我建議你在第一個，然後在第二個這樣的第一次分裂：

all = [] # Splitted messages will be stored here 
# mail_trail is the content of your mail trail 
sep = mail_trail.split("---------------ORIGINAL MESSAGE------------------") 
for msg in sep: 
    sep2 = msg.split("FROM") 
    if len(sep2) == 2: # has splitted 
     sep2[1] = "FROM" + sep2[1] # reappend the FROM since you need it 
    all.extend(sep2) # Add the messages in the array

這應該把你放在正確的軌道上。

你的代碼非常有用。但我能以其他方式做到這一點。我已經在問題中發佈了我的代碼。那麼extend（）函數在代碼中無法正常工作。它將字符串參數中的單個字符附加到列表中。append（）對我很好。 – skvp
