Starting Python with print

Let's try out Python for the first time by pressing the ► button on top of the code.  This code print (show in the output) the phrase "Hello World".

Try to change it into Hello Python, run it and see if the output changes.

Saving a value to a variable

Now, let's try using a variable. In this code, we've added a variable called name. The value of this variable is Andy. The print command print the value of the variable name.

Changing the variable value

You can simply use the = sign to change the value of a variable. Here, we try to change the value of the variable text.

Writing Comments in Python

Comments will not affect the program.
