Simple Calculator Project flashcards for Python

20 of 50 cards from the Simple Calculator Project deck — real questions with worked answers.

1. What is Python and why is it commonly chosen for a simple calculator project?

   Python is a high-level, interpreted, general-purpose programming language known for its readable syntax and ease of use, making it ideal for beginner projects like a calculator.

2. From which official website is Python downloaded for installation?

   From the official website python.org, which provides installers for Windows, macOS, and Linux.

3. During Windows installation, which checkbox should you enable so Python can be run from any terminal?

   The "Add Python to PATH" checkbox, which registers Python's location in the system PATH environment variable.

4. What command verifies that Python is correctly installed and shows its version number?

   Running $python --version$ (or $python3 --version$) in the terminal/command prompt.

5. What is the PATH environment variable's role after installing Python?

   It tells the operating system which directories to search for executables, so typing 'python' anywhere launches the interpreter.

6. What does IDE stand for, and what is its purpose?

   IDE stands for Integrated Development Environment; it is software that combines a code editor, interpreter/compiler, and debugging tools in one application to streamline coding.

7. Name three common IDEs or editors used for Python development.

   IDLE (bundled with Python), PyCharm, and Visual Studio Code (VS Code); Jupyter Notebook is another common option.

8. Which lightweight IDE comes bundled automatically with the standard Python installation?

   IDLE (Integrated Development and Learning Environment).

9. What file extension is used for Python source code files?

   The .py extension.

10. List the four basic arithmetic operations a simple calculator must support.

    Addition, subtraction, multiplication, and division.

11. What are the Python operators for the four basic arithmetic operations?

    Addition $+$, subtraction $-$, multiplication $\times$ written as $*$, and division written as $/$.

12. In Python, what is the difference between the $/$ and $//$ operators?

    $/$ performs true (float) division returning a decimal, while $//$ performs floor division returning the integer quotient rounded down.

13. What does the modulo operator $\%$ compute in Python?

    It returns the remainder of a division, e.g. $7 \% 3 = 1$.

14. What is the exponentiation operator in Python, and what does $2{**}3$ evaluate to?

    The $**$ operator raises a number to a power; $2^{3} = 8$.

15. How can each calculator operation be organized for clean, reusable code?

    By defining each operation as a separate function using the def keyword, e.g. def add(a, b): return a + b.

16. Write a Python function definition that adds two numbers a and b.

    def add(a, b): return a + b

17. What built-in function is used to read text input from the user in Python?

    The input() function, which displays an optional prompt and returns the entered value as a string.

18. What data type does the input() function always return?

    A string (str), regardless of what the user types.

19. Why must user input be converted before performing calculations?

    Because input() returns a string, and arithmetic requires numeric types, so the string must be converted to int or float.

20. Which functions convert a string to numeric types in Python?

    int() converts to an integer and float() converts to a floating-point (decimal) number.
