Editor to share with you what is the use of the Filter function in python, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Filter function

Filter built-in functions are very similar to map functions in that they also apply functions to sequence structures (lists, tuples, dictionaries). The key difference between the two is that filter () will return only the elements that the application function returns True.

We not only evaluated the True or False,filter () function of each list element, but also ensured that only elements matching True were returned. It is very easy to handle the two steps of checking expressions and building return lists.

What are the advantages of Python: 1. Easy to use. Compared with traditional languages such as Java, Java and C #, Python has less strict requirements on code format. 2. Python is open source and everyone can see the source code and can be ported to many platforms. 3. Python is object-oriented and can support both process-oriented programming and object-oriented programming. 4. Python is an explanatory language, the program written by Python does not need to be compiled into binary code, and can be run directly from the source code; 5. Python is powerful and has many modules, which can basically achieve all the common functions.

These are all the contents of the article "what is the use of Filter functions in python". Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
