I want to write code that locates every line in the file that begins with “From”, and extracts the portion of the e-mail address located between white space and the “@” symbol.

```
text = open('mBox.txt')

for line in text:
    if line.startswith('From') :
        print line

```

This is what I have so far. Not sure how to make it extract the specific part I want. This is for python 2.7
