Hello World Plus
- Enough words, we’re starting! In the console we want to start with a typical “Hello World” application. All you need to do is type in the following line and send it with Enter: With that we get our first output: Printis the function that we call here. Within the brackets, we give parameters which the function needs. Since it is a character string, we have to put also the quotation marks …

- As already said, variables can have different values. So that we can query them again, there is also a possibility for this. We can do this with if .. else. Here is an example: There is a lot to consider here: 1. At the end of the if, elif or elseline there must be a colon because we are saying that the condition has ended. We can also link several conditions. 2. For queries, the following o…

- Now we go one step further and look at so-called loops. Basically, these represent simple repetitions, whereby after each repetition (also called iteration) it is checked whether the specified condition is (still) true. The two types of loops are called ForLoop and WhileLoop. The while loop initially checks whether the query is true. Here’s an example: In each repetition, it is initially chec…
