LESSON 1. MOVING FROM BLOCKS

Learning outcomes

• compare Python and Scratch

• learn basic syntax in Python

• install Python on your computer and write your first line of code-

Previously you have learned how to program using a block-based programming language; the most common one that is used is Scratch. Block-based programming languages are a popular way to introduce people to programming. This is because you do not have to remember specific code and the different blocks click together like building bricks. To create programs using block-based programming, you use a graphical user interface, where you select the blocks you need and drag and drop, which makes it much easier to use.

Text-based programming requires you to remember the different syntax (code) that you will need and you have to type in the code that you require. There is no drag-and-drop option to build your programs and this can make it more challenging.

Python is normally installed on a computer with an Integrated Development and Learning Environment (IDLE). IDLE provides lots of functions that are useful when writing Python code.

​Read and write the keywords

​print("Hello world")

When using Python code you need to ensure that you type commands using lower-case letters. Otherwise will give you an error
