RegexdrillRepeated group: dotted numbers
A regex exercise from Regexdrill. Solve it with a pattern box with live highlighting in your browser, checked against hidden test strings, and it is checked the moment you submit.
The task
The whole line must match. Match one or more numbers separated by single dots, like 1, 1.2 or 10.0.3. No leading, trailing or doubled dots.
What this exercise teaches
\d+(?:\.\d+)* takes a number and then any count of dot-number pairs, so every dot sits between two numbers.
A hint if you get stuck
Match the first number, then repeat a group made of a dot and a number.
