Python doesn’t limit memory usage on your program. It will allocate as much memory as your program needs until your computer is out of memory. The most you can do is reduce the limit to a fixed upper cap. That can be done with the resource module, but it isn’t what you’re looking for.Memory Limit Exceeded Error: It typically occurs when no memory limit has been set. It means that the program is trying to allocate more memory than the memory limit for the particular problem. For Example, if the memory limit is 256 MB, then there is no need to write code that requires more than 256 MB of memory.Storing integers or floats in Python has a huge overhead in memory. Learn why, and how NumPy makes things better. Objects in Python have large memory overhead.
- To set a soft and hard limit on a particular resource, setrlimit() function is used.
- The soft limit is a value upon which the operating system will notify the process via a signal or typically restrict it.
- An upper bound on the values is defined by the hard limit and it may be used for the soft limit.

In Python, the buffer type object is used to show the internal data of a given object in a byte-oriented format. Python’s main use of buffers is storing and manipulating huge data arrays and processing them without creating copies. The buffer interface is only supported by strings , Unicode , arrays , and bytearrays .
What are common memory errors?
Memory errors may include remembering events that never occurred, or remembering them differently from the way they actually happened. These errors or gaps can occur due to a number of different reasons, including the emotional involvement in the situation, expectations and environmental changes.
