100-days-of-code VS RegExr

After earning my certificate for that program in July of this year, I continued my journey by starting freeCodeCamp's JavaScript certification. Shortly after starting the course I started the #100DaysOfCode Challenge on August 5 and on November 12 I completed the 100th day of that challenge.

In an effort to be intentional with my weekly reflections on the #100DaysOfCode Challenge, I want to focus this post on regular expressions. While completing the scripting challenges on freeCodeCamp I struggled and felt very frustrated with the challenges that involved regular expressions. Which means ... I needed to learn more about them and on a deeper level. So here goes!

Those are the triumphs, tribulations, and lessons I've learned from my first 50 days of the #100DaysOfCode Challenge. I'm looking forward to what comes next in the second half of the challenge and writing this post has helped me identify the direction I need to work toward. If you'd like to see my log entry for Day 50's study session, you can find in my GitHub repository for the #100DaysOfCode challenge.

When thinking about how I might compare an arrangement to the contiguous group of damaged springs, I used regexr.com to experiment with very specific regexs that used the numbers.

There are plenty of online regex tools to test and experiment with regex patterns. Some popular ones include RegExr, RegEx101, and RegexPlanet.

Using regexr.com it at least appears to work as expected.

If you are going to use RE's, use something like https://regexr.com/ to double check that they're doing what you want. I was suspicious of your 'cols = re.findall(r'\d+ .....', i)' line, and indeed it does miss some columns. You should rethink your column detection, and either not use REs or learn how to use capture groups and \w. There would then be no reason to use yet another RE in your column iterator to extract the numbers which you've already detected.

First time posting here, let me know if I need to edit post to conform to any rules. My issue is that I'm trying to match regex pattern to separate out the number of cubes drawn and its color but my Matcher object seems to not be returning any matches so it's throwing a no match found exception when I try to call digitMatcher.group(). I have tested my regex pattern on sites like regexr and it seems to pass there but it's not working for some reason here. I use the same type of regex on day one and it work there so I'm not sure where my regex pattern is failing here. I'm talking about specifically in my isGameValid() method where I create a matcher base on a pattern I made above. Through debugging I know that I separated the string color pairing correctly and that my Matcher object has the correct regex pattern, it's just not matching for some reason. Any help would be appreciated. Code below:

Regexr has been an invaluable tool as a beginner.

RegExr simplifies working with regular expressions. This online tool provides a visual interface for building and testing regex patterns in real-time, making regex less intimidating.

Ho did you arrive at the regex? I usually use a website to , such as https://regex101.com/, https://regexr.com/, https://regex-generator.olafneumann.org/ in combination of each other, as some explain better than the other.

I pulled this into regexr.com and it yielded the same results except it removed :41:
