I recently needed to extract a numeric suffix from a string value in Python. Initially I did the following: import re def extractNumSuffix(value): return (None if (search:=re.search(‘^\D*(\d+)$’, value, re.IGNORECASE)) is None else search.group(1)) Note that return has a single-line expression. So print(extractNumSuffix("test1030")) prints 1030 Tried it online at: https://repl.it/languages/python3 However, then I found out […]...

It uses different kinds of monitors […]...

After all 2038 is only 18+ years away. The DATETIME type is used for values that contain both date and time parts. MySQL retrieves and displays DATETIME values in 'YYYY-MM-DD HH:MM:SS' […]...
