# Returns all email addresses found in text.
#
# Uses a pattern to extract all the email addresses from the text using the 
# regular expression module findall function.  Note that the pattern will not 
# match 100% of email addresses due to edge cases, but should match for 99%+ of 
# common email addresses.

# Example text
text = """
    bla bla kevin@gmail.com more text joe.black@canada.ca more
