This article mainly introduces how to use Yield grammar in Python, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, let the editor take you to understand it.

Yield syntax in Python

For example, here we define a fibonacci () function that enumerates the first n digits of the Fibonacci sequence: 0, 1, 1, 2, 3, 5.

Def fibonacci (n): a = 0b = 1 nums = [] for _ in range (n): nums.appends (a) a, bb = b, axib return nums for i in fibonacci (10): print (I)

We can modify the fibonacci () function to use the yield syntax in Python:

First, rewrite append into yield.

Then delete the num list

In this way, the program will be the same as above, yield a says, every time we calculate an element, we send it out immediately; we don't need to wait for the whole list to be generated before outputting it; the advantage of yield is that it outputs in time in some very time-consuming operations.

Def fibonacci (n): a = 0b = 1 for _ in range (n): yield an a, bb = b, aquib return nums for i in fibonacci (10): print (I) Thank you for reading this article carefully.
