Throws MemoryError?

Question

Python

with open(r'C:\Users\AKSHIN\Downloads\errr.txt','r',encoding='utf-8')as f:
  	z = f.read().split('\n')
  	for line in z:
              print(line)

there are 6 million lines in the text editor, because of this, the error
Traceback (most recent call last) is displayed:
File "C:\Users\AKSHIN\Desktop\python\chtoto.py", line 2, in
z = f.read().split( '\n')
MemoryError

Answer 1

with open(file_name, 'r') as f:
    for line in f:
        # your code

In this case, the file will be read line by line, rather than loaded completely into memory. This is called a generator , read more here .

Answer 2

MemoryError - an exception that occurs in non-critical cases of exhaustion of free memory. You can handle it by removing objects from memory.
In general, you are doing bullshit. Output 6 million lines to the console. Your life is not enough to read every line. Output only those lines that contain the desired text (you can add more problems for yourself, use regular expressions - this is from a bearded joke)
