This website aims to give a quick reference for VB.NET, Python and pseudocode and is aimed primarily at teachers & students working towards a GCSE in Computer Science
VB.NET and Python are both programming languages designed to be understood and followed by computers. Pseudocode is not a programming language: it's written to be understood by humans so that they can turn it into any programming language.
Each exam board has published a document saying how they'll write pseudocode in their exams. The whole idea of syntax (a set of rules) for pseudocode is silly - it's not designed to be a programming language that is run by a computer. With this in mind, all exam boards state that you don't have to follow the syntax for 'their' version of pseudocode when you write out your own algorithms, but you should be able to understand their version of pseudocode when reading an algorithm in an exam.
Each skill has example code in VB.NET, Python and Pseudocode for Edexcel, Eduqas and OCR GCSE.

A string is some text that can contain more than one letter, number, space or punctuation mark.
This example writes the string "Hello world" to the file "output.txt"
An integer is a whole number (without any decimal places).
This example writes the numbers 1-10 into a file called numbers.txt
A csv file stands for a Comma-separated-values file. It will open as a spreadsheet (often in Excel) with lots of data organised into rows and columns.
When you open the csv file in a text editor (like notepad), the value for each cell is separated by a comma. Each row is written on a new line.
This example writes the 3 times table to a file called "timestables.csv":
