This article introduces the knowledge of "what is the function of python?". In the operation of actual cases, many people will encounter such a dilemma. Then let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

1. The value of the function is mainly reflected in the time of call, not when it is defined. Calling a function is like a box. Users do not need to know the code and logic, as long as they know how to use its functionality. Take the len () function as an example, we do not know the principle of this function, but it can achieve our purpose of obtaining the length of the list, which is its important value.

2. The main function of the function is abstraction, shielding complex internal details and allowing users to use its functions simply and clearly at a higher level. We said before that abstraction is one of the most important principles in the computer world, and function is its embodiment.

3. Because of the advantage of abstraction, the function also extends another function, code reuse, or code reuse. In other words, it is easy to reuse and save code. For example, if we want to use a program to calculate and output the absolute value of-3jcm456, mai le 0.03, when we are not using a function, we will write:

Number =-33if number > 0: print (number) else: print (- number) number = 456if number > 0: print (number) else: print (- number) number =-0.03if number > 0: print (number) else: print (- number) "what is the function of python" is introduced here, thank you for reading.
