What Is Memory Leak In Python And How To Fix It?

Generally, memory storage plays a most important role in Python programming, but “memory leak in Python” can lead to major storage issues. Undoubtedly memory is most important for keeping any program working effectively and efficiently, and even memory allows a program to take various instructions and collect data. 

If too much-unused data is stored up in your program and you forget to remove it, then your python program can face the problem of memory leaks.  In such a situation, it is required for you to remove that memory leak in the python program. 

Now the question that appears in every person’s mind is that “how can this be achieved.”

Firstly, you have to understand what memory leak in Python is, the causes, and the methods to resolve those issues. If you are disturbed by the issue of memory leaks, then don’t trouble. In this blog, we are going to discuss everything about a memory leak in Python in detail.

What Is A Memory Leak?

Usually, memory leaks are considered a continuous loss of available computer memory. When a program usually fails to return the storage obtained for temporary use, it is called a memory leak. 

The existence of memory leaks in any program can fill up the program’s storage and reduce storage space. In that case of lack of space, the program can start working slowly and be destroyed. 

What Is Memory Leak In Python

Like many other programs in the python language further, there is a memory leak. In simple words, we can say that while the memory of a python program is filled up with too many unused objects that don’t remove, it is considered a memory leak in Python. 

The most important thing is that memory management in Python is one of the best applications to solve these memory leak issues in python programming because it reads and writes the data. It is mainly used to erase the different unused data from storage. 

Major Causes Of Memory Leak In Python

Python programming also faces the challenge of memory leaks. The major cause behind the memory leak in Python is that the garbage collector does not eliminate and clear the unused or unreferenced data from Python programming. Undoubtedly, python developers have already tried to address the memory leak in the python problem by extending numerous unique features that can automatically free unused storage. Here we have mentioned the major causes of memory leaks in Python in detail:-

Large objects lingering in the memory that isn’t released

Generally, the lingering objects occur at that time when the domain controller can not replicate higher than the tombstone lifetime for a specific time interval. In such a situation, the domain controller usually reconnects to replication topology. Suppose you remove any object from the active directory service at that time when the domain controller is offline. In that case, that object stays in the domain controller as a lingering object. That type of lingering object that uses space that leads to the existence of memory leaks. 

Underlying libraries

Generally, python programming uses various libraries for modeling, data processing, and data visualization. It is noteworthy here that these python libraries will make python data tasks more comfortable. Moreover, it is considered one of the significant causes of Memory Leak In Python.

Reference styles in the code

Referencing style is one of the most important points as it determines whether memory leaks will exist or be avoided. Usually, every reference has a unique class and address information regarding objects being referenced, and assigned references do not make definite duplicate objects. But if an object is no longer in use in any program and can not be garbage collected as it is being referenced in a different place within the application, it will result in memory leaks. 

Different Methods To Fix Memory Leak In Python

No doubt, it is required for you to fix memory leaks in the program before it crashes your program. While you are working with Python, the Python memory manager solves problems related to python memory leaks. The application itself reads and writes data. Memory management in Python also helps you to erase any unused data from storage. It will become helpful in promoting the efficiency of memory as it cleanses all unused data from memory. Here we have mentioned the 2 different methods to fix memory leaks in Python:-

With the use of Debug method 

In this method, you will have to debug memory usages in python programming using the garbage collector inbuilt module. It will give you a list of all objects known by the garbage collectors. The debug method lets the user see where enough of the Python memory is being used or applied. After then the user can go ahead and filter everything based on usages. In such a condition, if you detect any object that is not in use, you can get cleared of them by removing them to avoid memory leaks in Python.

With the use of the Tracemalloc method 

Tracemalloc is considered one of the most top-notch inbuilt features of Python. When it comes to “memory leak in Python,” the Tracemalloc application allows you an effective and quick solution. With the Tracemalloc method, one can easily link an object with the exact place where it was allocated. 

It is also noteworthy here that this application enables users to establish the use of a particular usual function using memory within your program. It also provides a record of memory usage by a particular object, and one can use that record to find out the major causes of all types of memory leaks. When you are sure about the specific objects that lead to memory leaks, you can easily fix or eliminate them.

Final Words

At present, Python is known as one of the most used programming languages. But memory leaks in python can damage or commence to a slow capacity of the python program. In this blog, we have already discussed everything about Memory Leak In Python, including Different Methods To Fix Memory Leak In Python in detail. Therefore we hope that our blog will become very useful for you and it will clear all your doubts regarding it.

Frequently Asked Questions

Why does memory leak occur?

In computer science, a memory leak is a particular type of support leak it occurs when a computer programming wrongly manages memory allocations. Therefore the storage which is no longer required is not released. It is also noteworthy that a memory leak can happen if an object is stored in the memory or storage but can’t be accessed by the running code. 

How do you find memory leaks?

The best way to check a memory leak in any application is by looking at the RAM usage and examining the entire amount of memory utilized versus the total amount available.
