Question

BlackTom AI · Accepted Answer

When evaluating how to read a file in Python, we must recall the essential pieces of information the language needs to establish a file operation.
Option A: 'a file name and mode' is correct because Python's open() function requires at least the path to the file (the file name) and the mode in which to open it (e.g., 'r' for reading, 'w' for writing). These two pieces determine what the operation will do and how the data will be interpreted.
Option B: 'a file name and size' would be insufficient for open() because Python does not require or use a file size parameter to open a file; the size is not known or needed to perform the opening action and would not affect how the file is accessed.
Option C: 'a file name and data type' is not how Python specifies access to a file. The data type is a property of the data once read or written, not an input needed to open the file. The open() call does not require a data type parameter to function.
Option D: 'a file name and file properties' is vague and not part of the standard open() signature. While there are metadata attributes (like encoding or buffering) that can be specified in opens, the core required inputs are the file name and the mode; 'file properties' as a general term does not map to a concrete parameter in the open() call.
In summary, the minimal and necessary inputs for opening a file to read in Python are the file name and the mode in which you intend to access it; the other options introduce extraneous or incorrect requirements that are not part of the standard file-opening procedure.
