Regex that checks if string only contains numbers and special characters
Question:
I am trying to make an if function that checks if a string contains only a mixture of numbers and any special characters. For example:
Input: "Hello"
>>> False
Input: "$34&@!5^"
>>> True
Input: "Hello34#&%"
>>> False
I’m new to Regex and I’m not sure how to write the Regex for this. I know checking for special characters is r'^[_W]+$' , and isdigit() can be used to check numbers only, but how do I combine both? I’m confused on how to combine [0-9] and the other symbols to write a Regex for this.
Answers:
You can use ^[W0-9_]+$ to match all non-word characters, _, and 0-9.
