The content of this article is about the implementation method of memory recycling mechanism of Python code program. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

We know that we have defined a variable. If we do not need this variable, we need to release the running memory of the variable, so we can release this memory in two common ways. Let’s look at the following two examples:

1.python recycling mechanism

nav = 1
nav = 2
print(nav)

Output result: 2

So nav = 1 will not work

We set two variables with the same name at the same time, then the previous variables will be automatically cleared periodically (not effective immediately)

2. Manual clearing

nav = 1
print(nav)
del nav

In this way, the nav variable will be cleared manually Cleared.

The above is the detailed content of How to implement the memory recycling mechanism of python code program. For more information, please follow other related articles on the PHP Chinese website!
