GUID regex Python
GUID is an acronym for Globally Unique Identifier and used for resource identification. The term is generally used instead of UUID when working with Microsoft technologies.
GUID regex
Below is a simple regular expression to match a guide in a given string:
"^(?:\\{{0,1}(?:[0-9a-fA-F]){8}-(?:[0-9a-fA-F]){4}-(?:[0-9a-fA-F]){4}-(?:[0-9a-fA-F]){4}-(?:[0-9a-fA-F]){12}\\}{0,1})$"
Enter a text in the input above to see the result
Example code in Python:
import re
# Validate GUID
words_pattern = "^(?:\\{{0,1}(?:[0-9a-fA-F]){8}-(?:[0-9a-fA-F]){4}-(?:[0-9a-fA-F]){4}-(?:[0-9a-fA-F]){4}-(?:[0-9a-fA-F]){12}\\}{0,1})$"
re.match(words_pattern, '51d52cf1-83c9-4f02-b117-703ecb728b74') # Returns Match object
re.match(words_pattern, '{51d52cf1-83c9-4f02-b117-703ecb728b74}') # Returns Match object
re.match(words_pattern, '{51d52cf1-83c9-4f02-b117-703ecb728-b74}') # Returns None
# Extract GUID from a string
words_extract_pattern = "(?:\\{{0,1}(?:[0-9a-fA-F]){8}-(?:[0-9a-fA-F]){4}-(?:[0-9a-fA-F]){4}-(?:[0-9a-fA-F]){4}-(?:[0-9a-fA-F]){12}\\}{0,1})"
re.findall(words_extract_pattern, 'Resource {51d52cf1-83c9-4f02-b117-703ecb728b74} is down') # returns ['{51d52cf1-83c9-4f02-b117-703ecb728b74}']
