- Why is it considered good practice to open a file from within a Python script using (a) instead of (b)? (a) with open(‘textfile.txt’,’r’) as f: f.readlines() (b) f=open(‘textfile.txt’,’r’) f.readlines() f.close() a. When you open a file using the with keyword in Python, Python will make sure the file gets closed, even if an exception or error is thrown. b. The with keyword lets you choose which application to open the file in. c. The with keyword acts like a for loop, and lets you access each line in the file one by one. d. There is no benefit to using the with keyword for opening a file in Python.I m getting this memory error message?
