Question 1

What’s a computer program?

1 / 1 point

A set of languages available in the computer

A process for getting duplicate values removed from a list

A list of instructions that the computer has to follow to reach a goal

A file that gets copied to all machines in the network

Correct

You nailed it! At a basic level, a computer program is a recipe of instructions that tells your computer what to do.

 

 

 

 

Question 2

What’s the syntax of a language?

1 / 1 point

The rules of how to express things in that language

The subject of a sentence

The difference between one language and another

The meaning of the words

Correct

Right on! In a human language, syntax is the rules for how a sentence is constructed, and in a programming language, syntax is the rules for how each instruction is written.

 

 

 

 

Question 3

What’s the difference between a program and a script?

1 / 1 point

There’s not much difference, but scripts are usually simpler and shorter.

Scripts are only written in Python.

Scripts can only be used for simple tasks.

Programs are written by software engineers; scripts are written by system administrators.

Correct

You got it! The line between a program and a script is blurry; scripts usually have a shorter development cycle. This means that scripts are shorter, simpler, and can be written very quickly.

Question 4

Which of these scenarios are good candidates for automation? Select all that apply.

1 / 1 point

Generating a sales report, split by region and product type

Correct

Excellent! Creating a report that presents stored data in specific ways is a tedious task that can be easily automated.

Creating your own startup company

Helping a user who’s having network troubles

Copying a file to all computers in a company

Correct

Nice work! A task like copying files to other computers is easily automated, and helps to reduce unnecessary manual work.

Sending personalized emails to subscribers of your website

Correct

Great job! Sending out periodic emails is a time-consuming task that can be easily automated, and you won't have to worry about forgetting to do it on a regular basis.

Question 5

What are semantics when applied to programming code and pseudocode?

0 / 1 point

The rules for how a programming instruction is written

The difference in number values in one instance of a script compared to another

The effect the programming instructions have

The end result of a programming instruction

Incorrect

Not quite. The end result of a program function is described as the output.

 

 

Code

 

friends = ['Taylor', 'Alex', 'Pat', 'Eli']

for friend in friends:

print("Hi " + friend)

 

 

Output:

Hi Taylor
Hi Alex
Hi Pat
Hi Eli

Let's check whether you soaked all that in with a quick question! Select all options that explain why Python is relevant to today’s IT industry.

Python scripts are easy to write, understand, and maintain.

Correct

Woohoo! Python is a language that tries to mimic our natural language and so Python scripts are generally easy to write, understand and maintain.

There are many system administration tools built with Python.

Correct

You got it! Over the years, the Python community has developed a lot of additional tools that can be used by system administrators to get their job done.

Python was written by Guido van Rossum in 1991.

Python is available on a wide variety of platforms.

Correct

Well done, you! Python is available on Windows, Linux, MacOS and even on mobile devices, making it a great tool for IT specialist looking to create scripts that can work across platforms.

There have been multiple major version releases over the years which incorporate significant changes to the language.
