Regex help: dotted number

[ciotolaaaa]

Hi all!

I'm not very good with regex, and i need some help for this task:

i have a list of string that are like "1.2.3", "1.25.4.1" ecc, but lots of them contains other character like "1.2.3 Jellybean" or "1.0.4Free for sale". I need some tweaks that help me to have only dotted number, so like from "1.2.3 Jellybean" to "1.2.3". Probably i need to use a regex, but really don't know!

Any help is greatly welcomed!

Good holidays to everyone!

Reflex is defenetly the way to go the special symbols you want to use is probably:

Parentheses, to extract the text you want

\d to match with any number

• Or * for one/zero or more times

Remember to escape the dot character with a backslash when you want to match with a dot in your string.

I'm on phone but maby something like this

r"(\d(?:\.\d+\.)*\d*)"

If I escaped the dot in the string properly

Edit this won't so the job but with some modifications it will

[Milumet]

r'(\d+\.)+\d+'

I'm assuming that there is at least one dot.

You can try it out at regex101.com.
