How do I combine wrfout.nc files?

Hi everyone.

I posted here before about my problem in installing WRF. I was able to successfully install it now thanks to some advices on that post. Now, I ran some GFS data through WRF and was able to produce wrfout files on a 3-hourly interval. For post-processing, I plan to use Panoply since it's really basic click-and-play kind of thing, but I've been seeing videos in YouTube of them using only one wrfout.nc file, but it's a combination of all their wrfout files. I was looking at this one video and found that they used Python to combine their files, however I have no background knowledge yet in coding in Python (or any language at all).

Is there an easier way to do this? Or can you only do this through coding?

Image below shows the wrfout files I have. The destination to it is "C:\Users\HP\Dropbox\PC\Documents\Python Codes\wrfout-files". Hope this information helps. TIA!
