How to Clear Memory in Python?

Estimated read time 1 min read

In Python, you can clear memory by deleting objects that are no longer in use and running the garbage collector to reclaim memory from unreachable objects. Here are some methods to clear memory in Python:

  1. Delete objects: You can delete objects by using the del statement. This will remove the reference to the object, allowing Python’s garbage collector to reclaim the memory.
x = [1, 2, 3]
del x
  1. Use the gc module: The gc module provides functions for garbage collection. You can call gc.collect() to perform garbage collection and free up any unused memory.
import gc
gc.collect()
  1. Use generators and iterators: Generators and iterators can be used to generate and process data one item at a time, rather than generating a large data structure all at once. This can help to reduce memory usage.
def my_generator():
    for i in range(100):
        yield i

for x in my_generator():
    print(x)

Note that Python’s garbage collector runs automatically, so you don’t usually need to manually perform garbage collection. However, if you are working with large datasets or long-running programs, you may want to use the gc module to manually trigger garbage collection and free up memory.
