Introduction to Python: Lesson 1

Introduction

What is Python

Python is a computer programming language that is straightforward and fairly easy to learn.

During this unit you will start out learning how to write a simple program of just a couple of words. As the weeks progress you will eventually create your own chat bot with whom you can hold a conversation.

1a. Starting Off

Watch this:

• Watch this video to find out how to open Python. You will need headphones

Do this:

• Create a folder in your area, call it 'Python Year 7'

Do this:

Open and save this document into your area

Do this:

Right click on the blue icon (on the right) Save the audio file to a new folder in your area Give your new folder a sensible name

Try this:

• Open Python on your computer
• Make sure that you have both the Shell and the program window open

Write this:

• Go to your worksheet and answer question 1b

Create this:

• Go to your worksheet and answer question 1b

Check your answer:

• Check you answer
• Check

Discuss this:

• Open Python on your computer
• Make sure that you have both the Shell and the program window open

Test Yourself:

• Open Python on your computer
• Make sure that you have both the Shell and the program window open

Read this:

• Open Python on your computer
• Make sure that you have both the Shell and the program window open

Remember this:

• In Python, you can use either single or double speech marks, but if you start a line of code with a single speech mark then you must finish with the same. You cannot mix them.

Homework:

• With the exception of the gold star challenges, complete everything else for homework

Information:

• Look at your code. Do you notice that the two variables are joined with a + symbol? The + tells python to join or 'concatenate' the two variables together.

Code this:

• In the program window type the following code EXACTLY as shown:

print ("Hello World") 

• Press F5 to run your program. Save it to your folder with a sensible name.
• Did you see Hello World appear in the Shell?
• If you didn't then go back and look at your code and make sure that it looks exactly like the code written on this page.

• Press F5 to run your program.
• What happened?

Save this:

• Save your worksheet to your area
• Save and close any Python programs that you still have open

Extension Task:

• Start a new project.
• Use the skills that you have learned to set up a conversation between two new sprites
• Add in suitable timings, pauses, costume changes, sounds etc.

Gold:

• Gold
• Check

Silver:

• Gold
• Check

Bronze:

• Gold
• Check

Code this:

• In the program window, change the code to look like this (notice the capital P):

Print ('Hello World') 

• Press F5 to save and run your program
• What happened?
• On your worksheet explain what caused the error message

Error:

• If you got an error message go back to your code and check it carefully:
• did you use an opening and closing bracket?
• did you use speech marks at the beginning and end of the value?
• did you use a capital P for print instead of a small p?
• did you use a capital F for the first 'forename' and a lower case f for the second?

• Did it work? If not, try again.
• Hyperlinks!

Do this:

• Create your own bitmap graphic of a space invader sprite.
• Use the grid underneath the timer to create your image.
• You have 5 minutes to complete this activity. Start the timer now by pressing 'Play'.
