Worked practice questions

Python converts its instructions into machine language using an:

  1. Interpreter
  2. Interceptor
  3. Interlocker
  4. Interrupter
Show answer and solution

Correct answer: A. Interpreter

1. Source code is not directly understood by the computer. 2. A translator stands between the two. 3. Python uses an interpreter to convert its instructions into machine language. 4. So the answer is an interpreter. _Source: syllabus Computer Science, Ch 5 'Getting Started with Python'_

Python source code files are saved with which extension?

  1. .pe
  2. .py
  3. .pi
  4. .pa
Show answer and solution

Correct answer: B. .py

1. A script must be recognisable as Python on disk. 2. The file name carries a specific ending. 3. Python scripts are saved as files where the file name has extension.py. 4. So the answer is.py. _Source: syllabus Computer Science, Ch 5 'Getting Started with Python'_

In Python, a comment starts with which sign?

  1. Cash
  2. Sash
  3. Hash
  4. Dash
Show answer and solution

Correct answer: C. Hash

1. A note for the reader must be marked so the interpreter skips it. 2. One character does that marking. 3. In Python, a comment starts with the hash sign. 4. Everything after it on that line is ignored. _Source: syllabus Computer Science, Ch 5 'Getting Started with Python'_
