Question

Which of these statements are true? Select 2 options.

1) If you open a file in append mode, Python creates a new file if the file named does not exist.
Python can only be used with files having ".py" as an extension.
If you open a file in append mode, the program halts with an error if the file named does not exist.
In a single program, you can read from one file and write to another.
The new line character is "\\ewline".

Answer 1

Python creates a new file when opened in append mode if it doesn't exist and can handle files with any extension. It's also possible to read from one file and write to another in the same Python program.

Step-by-step explanation:

The question is about file handling in Python, more specifically about opening a file in append mode and understanding file extensions. When a file is opened in append mode, if the file does not exist, Python creates a new file. This is different from the write mode which will also create a new file but will overwrite the existing file if one exists. Moreover, contrary to one of the statements, Python can work with files of any extension, not just ".py", which is the extension for Python source code files. Therefore, the statement about Python only being able to work with ".py" files is incorrect. Also, the new line character in Python is represented as "\\", not "\\ewline".

Moreover, it's common practice in programming with Python to read from one file and write to another within the same program. This is a basic file operation and is supported by Python's built-in functionalities. Hence, this statement is true and presents a fundamental aspect of file I/O (input/output) operations.

Answer 2

Two statements are true: Python will create a new file if one doesn't exist when using append mode, and you can read from and write to different files within the same Python program. Python can work with files of any extension, and the newline character is "\\".

Step-by-step explanation:

Among the statements provided regarding file operations in Python, the following are true:

1. If you open a file in append mode, Python creates a new file if the file named does not exist. This means that using the append mode ('a' or 'a+') will not result in an error if the file you're trying to append to doesn't exist; instead, a new file with the specified name will be created, and your data will be written into this new file.
2. In a single program, you can read from one file and write to another. Python supports multiple file operations within the same program, allowing you to handle different files for different purposes, like reading from a source file and writing the processed data into a target file.

It's important to note that the statement about Python only being able to use files with a ".py" extension is incorrect; Python can work with files of any extension as long as it has the necessary access and the format of the content is something Python can handle (text, binary, etc.). Also, the new line character in Python is represented by "\\", and not "\\ewline" as stated in the options.
