All questions of Functions for Humanities/Arts Exam

Understanding the Correct Answer: Reduces Code
The statement highlights the importance of code efficiency in programming. The correct answer, "Reduces code," focuses on the benefits of minimizing redundancy in software development.
Key Benefits of Reducing Code:
- Eliminates Duplication: By avoiding the repetition of the same code in multiple places, developers can write a function once and call it wherever needed, which significantly cuts down the overall amount of code.
- Easier Maintenance: When code is reduced, any changes or bug fixes only need to be made in one location. This reduces the risk of introducing errors when updating duplicated code across various sections.
- Improved Debugging: With less code to sift through, identifying and fixing issues becomes more straightforward. Bugs are easier to trace back to their source when they exist in a single location.
- Increased Clarity: A program with less repetitive code is often easier to read and understand. This clarity helps other developers (or the original developer at a later time) to follow the logic and structure of the code more effectively.
Conclusion:
While options like "Increases readability" and "Increases reusability" are also valid benefits of efficient coding practices, the primary focus of the question is on reducing the amount of code written. Hence, the correct answer is "Reduces code," as it encapsulates the essence of minimizing redundancy, leading to easier maintenance and debugging.

Explanation:

The `id()` function in Python is used to identify the identity of an object. It returns a unique integer identifier for the object. This identifier is guaranteed to be unique and constant for the lifetime of the object.

The `id()` function takes one argument, which is the object whose identity needs to be determined. This argument can be any object in Python, including variables, functions, classes, and instances.

Example:

```python
x = 10
y = x
print(id(x)) # Output: 140717836481840
print(id(y)) # Output: 140717836481840
```

In the above example, both `x` and `y` are assigned the same value `10`. When we use the `id()` function to determine their identity, we get the same integer identifier for both.

Conclusion:

Thus, the correct answer to the question is option B - `id()`.

Explanation:

Python is a widely used high-level programming language that is known for its simplicity and readability. It was created by Guido van Rossum and first released in 1991.

Python Extension:

The extension of Python files is .py. When you write code in Python, you save it with a .py extension. This extension is recognized by Python interpreters and allows the operating system to identify the file as a Python script.

Why .py Extension:

The .py extension is used for Python files to differentiate them from other types of files and indicate that they contain Python code. Here's why the .py extension is used:

1. Consistency: The .py extension is used across different operating systems, such as Windows, macOS, and Linux. Using a consistent extension helps maintain compatibility and ensures that Python scripts can be recognized and executed on different platforms.

2. Identification: The .py extension helps in identifying Python files easily. When you see a file with a .py extension, you immediately know that it is a Python script.

3. Python Interpreter: Python interpreters, which execute Python code, recognize files with the .py extension. When you run a Python script, the interpreter reads the .py file, interprets the code, and executes it.

4. Code Organization: Using the .py extension helps in organizing and managing Python code. It allows developers to easily identify Python scripts within a project or directory.

5. Editor Support: Most code editors and Integrated Development Environments (IDEs) have built-in support for Python and recognize files with the .py extension. This support includes syntax highlighting, code suggestions, and debugging capabilities specific to Python.

Conclusion:

In conclusion, the extension of Python files is .py. This extension is used to identify Python scripts, ensure compatibility across different platforms, and enable Python interpreters to execute the code. Using the .py extension is a standard practice in the Python community and helps in organizing and managing Python code effectively.
