Python programming 

Lesson 1 

KEY OBJECTIVE

Conquer: To understand the need for functions in a program.

Aspire: Create your own functions in python.

Task 1 - PREDICT

What do you think this code will do?

What will this code do?

Lets check your prediction 

Run the code

Click the green play button

Run the following code:

Functions

A function is a set of code that runs on a command word. 

What do you think the command word is for this code?

DEF

Def is short for define function. 

We are telling the computer that any code under this code word needs to be run we we use the code word. 

INVESTIGATE and MODIFY

Using the code you have try and:

• Make it say a different message
• Make the message print 5 times by calling the function multiple times
• CLICK ME

Predict:


What will the outcome of this code be?

1. Hello world will appear
2. "Hello world" will appear
3. Nothing
4. An error will occur

Predict:

What will the outcome of this code be?

1. Error on line 4
2. Error on line 7
3. Hello there
4. Nothing

MAKE

Create your own program that will:

• Have a function called "computing" that prints the message "I love computing"
• Make sure you call that function. 

• Here is a blank coding window
• EXTENTION: Create another function for your favorite film, food or tv show. 

What is Syntax?

• The way we write a line of code is important.

• Think about our 'English'. It is important that we use correct punctuation, such as Commas and Full Stops.

• If we do not use the correct symbols and spellings in our Python coding, then the computer will not be-able to run our programs.

What is debugging?

• Debugging code refers to the process of identifying and fixing errors, bugs, or defects in a computer program that we have created.
  

• An error occurs, when you have done something wrong in your program. You could have spelt something wrong or even missed out a symbol...

Debugging Continued...

Create with code, shows you where your error is. Below is a screenshot that shows this.

Task 2 - Debugging

In this task, you will need to debug the code using the error messages that create with code provide.
