def obfuscate(email):
    return email.replace('@',' [at] ').replace('.',' [dot] ')

'''
Many people choose to obfuscate their email address when displaying it on the Web.
 One common way of doing this is by substituting the @ and . characters for their
 literal equivalents in brackets.

Example 1:

user_name@example.com
=> user_name [at] example [dot] com

Example 2:

af5134@borchmore.edu
=> af5134 [at] borchmore [dot] edu

Example 3:

jim.kuback@ennerman-hatano.com
=> jim [dot] kuback [at] ennerman-hatano [dot] com

Using the examples above as a guide, write a function that takes an email address
 string and returns the obfuscated version as a string that replaces the
 characters @ and . with [at] and [dot], respectively.

    Notes

        Input (email) will always be a string object. Your function should return a string.

        Change only the @ and . characters.

        Email addresses may contain more than one . character.

        Note the additional whitespace around the bracketed literals in the examples!
