如何使用textblob机器学习来检测正确的电子邮件地址？

Question

我想检测正确的电子邮件地址，但我的代码是给我的标签与大概率的数据集，显然它不象我预期的工作

代码如下：

from textblob.classifiers import NaiveBayesClassifier
files = [
  ("data_train/email_positive.txt", "yes"), 
  ("data_train/email_negative.txt", "no")
]
train = []; cl = None

for file_txt in files:   
    email_train_raw = []        
    with open(file_txt[0]) as f: 
        email_train_raw = f.readlines()

    for email in email_train_raw:
        e = email.replace("\n", "")
        train.append( (e, file_txt[1]) )

cl = NaiveBayesClassifier(train)
print cl.classify("wrong_email@2x.png")
# Output: yes 
# it would be: "no"

一些正确的电子邮件数据集：

hello@3commerceinc.com
sales@ablefreight.com
dispatchwaycross@absolutewl.com
ops@absolutewl.com
tol@absolutewl.com
email@gmail.com
email@hotmail.com
. . . 

一些不正确的电子邮件数据集：
