I am trying to detect email from clipboard using regex.

Sample Input:

sifii203@gmail.com
sifat@yahoo.com
1232@hotmail.com

Code:

import pyperclip,re

text = pyperclip.paste()
if text:
    agentNamesRegex = re.compile(r'\w+\d*@\w+\.\w+')
    matches = []
    print(agentNamesRegex.findall(text))

Output:(that I am getting)

['sifii203@gmail.com', 'sifat@yahoo.com', '1232@hotmail.com']

Why is 1232@hotmail.com part of the output when I have predefined \w+ which means at least one character will be the suffix?

What am I doing wrong?

Do you know what `\w` includes? Read e.g. https://docs.python.org/3/library/re.html#regular-expression-syntax – jonrsharpe Jan 28 '17 at 18:26
`\w` matches letters or digits or `_`. `\d*` does not have to match anything, it only matches 0+ digits. – Wiktor Stribiżew Jan 28 '17 at 18:28
@WiktorStribiżew thanks for the correction! But how would i just catch characters like a,b,c only ? – Md Sifatul Islam Jan 28 '17 at 18:32
Use `[a-zA-Z]+` – Wiktor Stribiżew Jan 28 '17 at 18:33
thnx that works fine! – Md Sifatul Islam Jan 28 '17 at 18:34
