从邮箱数据文件中获取电子邮件地址

问：

我写了下面的程序。有没有更好的方法（有效的方法）来重写代码？

##Read 通过邮箱数据。找到以“From”开头的行，并将其拆分为单词。获取电子邮件 #address（第二个单词）并打印。还要计算“发件人”行的总数并在末尾打印。

with open("mbox-short.txt", mode='r') as f:
        data = f.readlines()
count=0
for line in data:
    words = line.split()
    if line.startswith ('From:'):  continue
    if line.startswith ('From'):  
      email_sent_by= words[1]
      print(email_sent_by)
      count=count+1
print('There were',count,'lines in the file with From as the first word.')
