This article mainly explains "the role of cyclic structure in python". The content of the explanation in this article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "the role of cyclic structure in python".

The following mainly introduces several ways to realize the loop structure in Python: for loop, while loop, generation, high-order function, vectorization.

One, for cycle

Second, while cycle

Third, generative formula

Generator is a lightweight loop structure with simple grammatical structure and very comfortable to use.

Generative is one of my favorite python grammatical features. Can be used to generate lists, collections and dictionaries.

Fourth, higher-order function

Python provides some higher-order functions, which can call other functions as arguments.

The functions of these higher-order functions include cyclic structures. Commonly used high-order functions include: map,reduce,filter,sorted.

Fifth, vectorization

Vectorization is a very powerful way to replace loop statements.

The array structure in python supports vectorization.

Here is only a simple example.

Sixth, cycle control

Break: jump out of the loop at this layer.

Continue: jump out of this cycle and move on to the next.

Pass: no operation. Code stake.

Seventh, thinking practice

15. Use for loop, while loop, generator and map/reduce to determine whether an integer is a prime (primes are those integers that are not divisible by other integers except 1 and itself, and the smallest prime is 2).

Thank you for your reading, the above is the content of "the role of cyclic structure in python". After the study of this article, I believe you have a deeper understanding of the role of circular structure in python, and the specific use needs to be verified in practice.
