I am using the below regex pattern to validate numerics and spaces

 "^[0-9\s]{1,50}" 

Attaching sample payload which i am receiving

 {"numberval":""}
 {"numberval":" "}
 {"numberval":"10,11,12"}

I am using python re module and compile method to validate the regex. can any one help me with regex which can validate both the inputs?

CodePudding user response：

Assuming you consider valid whitespace only or comma separated numbers, you could use this regex pattern:

^(?:\s*|\d (?:,\s*\d )*)$

Demo

This regex pattern says to match:

• ^ from the start of the value
• (?:
  • \s* either zero or more whitespace characters
  • | OR
  • \d a number
  • (?:,\s*\d )* followed by zero or more other comma separated numbers
• )
• $ end of the value
