Python 3.7.3 (v3.7.3:ef4ec6ed12, Mar 25 2019, 22:22:05) [MSC v.1916 64

 >>> import re
 >>> pattern = r'[0-9]{4,6}'
 >>> pattern2 = r'[0-9][0-9][0-9][0-9]([0-9]){0,2}'
 >>> re.search(pattern, '1234')
<re.Match object; span=(0, 4), match='1234'>
 >>> re.search(pattern2, '1234')
<re.Match object; span=(0, 4), match='1234'>
