Editor to share with you how to achieve python counter, I believe that most people do not know much about it, so share this article for your reference, I hope you will learn a lot after reading this article, let's go to understand it!

Counter

The collection is also a good standard library in the module. Here we introduce the counters in the collection. Using counters, you can easily get a count of a list. This is useful for getting the total number of values in the data, the empty count of the data, and viewing the unique values of the data.

"Why not just use Pandas?" Using Pandas to achieve this is undoubtedly much more difficult, and this is just another dependency that needs to be added to the virtual environment when deploying the algorithm. In addition, the counter type in Python has many features that the Pandas family does not have, which makes it more useful in some cases.

A = collections.Counter ([1, 1, 2, 3, 3, 3, 3, 4, 5, 6, 7]) A Counter ({3: 4, 1: 2 Counter 2: 2: 2, 4: 1, 5: 1, 6: 1, 7: 1}) A.most_common (1) [(3, 4)] A.most_common (3) [(3, 4), (1, 2), (2P 2)] these are all the contents of the article "how to implement counters in python" Thank you for reading!
