Please be aware that when using function/method to merge dictionaries, the order of dictionaries you pass into function/method really matters in case key duplicate happens. Python will refer to that order to decide which key/value pair will be updated in the destination dictionary.

Finally someone who explains this stuff in a much simpler and less confusing way. Thank you so much!

My preferred method is unpacking operator. I've never tried anything else. Definitely will give it a go in my next practice. Thanks buddy!

Just made a switch to Python from Java and love it from first sight, it's easy and strong, how many Python lovers are here

I remember the first time I did an exercise on dictionaries merging and I need to write about 10 lines of code with for loop. Thanks for showing us better way to get the task done more quickly
