Introduction to Python and program modes

1. Who developed the Python programming language?

Dennis Ritchie
Guido van Rossum
Bjarne Stroustrup

Guido van Rossum created Python in the late 1980s at CWI in the Netherlands.

2. Python was released in which year?

1989
1991
1995

Python 0.9.0 was first released to the public in February 1991.

3. Python is a _______ programming language.

Low-level
High-level
Machine-level

Python is high-level because it is user-friendly and looks similar to English.

4. Which feature allows Python to run on different platforms like Windows, Linux, and Mac?

Scalability
Portability
Case-sensitivity

Portability means the same code can run on various operating systems without major changes.

5. Python is ‘Interpreted’. This means:

It converts all code to binary at once
It executes code line-by-line
It doesn’t need an interpreter

Interpreted languages execute instructions directly and line-by-line.

6. Python is ‘Open Source’. What does this imply?

It is very expensive
Its source code is freely available to everyone
It can only be used on Windows

Open Source means anyone can view, modify, and distribute the source code.

7. Python was named after:

A large snake
A comedy TV show (Monty Python)
The creator’s pet

It was named after “Monty Python’s Flying Circus,” a BBC comedy series.

8. Which of the following is NOT a feature of Python?

Easy to use
Compiled only
Expressive language

Python is primarily an interpreted language, though it compiles to bytecode.

9. Python is ‘Case Sensitive’. What is the result of choosing ‘score’ vs ‘Score’?

They are the same
They are different identifiers

In Python, capitalization matters. Variable names are distinct based on case.

10. Large standard library support is a benefit of Python. This is often called:

Heavy Coding
Batteries Included
Plug and Play

“Batteries Included” refers to Python’s extensive built-in modules and libraries.

11. Which mode is best for testing single lines of code instantly?

Interactive Mode
Script Mode

Interactive mode gives instant output for every command entered.

12. What is the prompt symbol in Interactive Mode?

>>>
###
$$$

The triple chevron (>>>) is the default Python shell prompt.

13. In which mode can you NOT save your commands for later use?

Script Mode
Interactive Mode

Commands in interactive mode are lost once you close the window.

14. What is the file extension for a Python script?

.txt
.py
.exe

Python script files must end with the .py extension.

15. To create a new file in IDLE, you navigate to:

File -> New File
Edit -> New File

File -> New File opens the Script Mode editor in IDLE.

16. Which key is the shortcut to ‘Run’ a script in IDLE?

F1
F5
F10

Pressing F5 saves and executes your current script.

17. Script mode is suitable for:

Quick one-line calculations
Developing large programs

Script mode allows you to write, save, and edit long programs.

18. What happens when you type 5 + 2 in Interactive mode?

It displays 7 immediately
It does nothing until you save
It gives an error

Interactive mode evaluates expressions and prints the result immediately.

19. In Script Mode, to see the output of 5 + 2, you must use:

display() function
print() function
show() function

Unlike Interactive mode, Script mode requires the print() function to output data to the console.

20. Which software environment comes bundled with Python for writing code?

Visual Studio
IDLE
Notepad++

IDLE (Integrated Development and Learning Environment) is Python’s own basic IDE.
