1.1      Introduction

1.1 Q1: Which of the following statements is false?

a. Software (that is, the Python instructions you write, which are also called code) controls hardware (that is, computers and related devices).

b. Programmers use the Python Standard Library and various other libraries to “reinvent the wheel.”

c. Programmers use libraries to create software objects that they interact with to perform significant tasks with modest numbers of instructions.

d. IPython executes Python instructions interactively and immediately shows their results.

Answer: b. Actually, programmers use the Python Standard Library and various other libraries to avoid “reinventing the wheel.”

d. All of the above statements are true.

Answer: a. Actually, decades ago, most computer applications ran on “standalone” computers (that is, not networked together).

 

1.2      Hardware and Software

1.2 Q1: Which of the following statements is false?
