How Can I Read Large Text Files Line by Line to Avoid Memory Overload?

Reading Large Text Files Line by Line without Memory Overload

When dealing with massive text files exceeding memory capacity, reading them line by line without overloading memory becomes crucial. A memory-efficient approach involves utilizing a for loop directly on the file object.

Using with open(...) creates a context manager that automatically closes the file after reading. Here's an example:

with open("log.txt") as infile:
    for line in infile:
        print(line)

This code reads the file "log.txt" line by line, avoiding memory issues associated with loading the entire contents. Each line is processed within the loop, ensuring efficient handling of large files without compromising system resources.
