Python is a popular programming language. It was created by Guido van Rossum
Python can be used on a server to create web applications Python can be used alongside software to create workflows. Python can connect to database systems. It can also read and modify file Python can be used to handle big data and perform complex mathematics.
Python works on different platforms (Windows, Mac, Linux, Raspberry Pi, etc).Python has a simple syntax similar to the English language.Python has syntax that allows developers to write programs
The most recent major version of Python is Python 3, which we shall be using in this tutorial. However, Python 2, although not being updated with anything other than security updates, is still quite popular.In this tutorial Python will be written in a text editor. It is possible to write Python in an Integrated Development Environment, such as Thonny, Pycharm, Netbeans or Eclipse which are particularly useful when managing larger collections of Python files.Python was designed for readability, and has some similarities to the English language with influence from mathematics.
Python relies on indentation, using whitespace, to define scope.
Python Comments
- Comments can be used to explain Python code.
- Comments can be used to make the code more readable.
- Comments can be used to prevent execution when testing code.
- Comments can be placed at the end of a line, and Python will ignore the rest of the line
- A comment does not have to be text that explains the code, it can also be used to prevent Python from executing code
Variables are containers for storing data values
Python Variables
- Python has no command for declaring a variable.
- A variable is created the moment you first assign a value to it.
- Variables do not need to be declared with any particular type, and can even change type after they have been set.
- If you want to specify the data type of a variable, this can be done with casting.
String variables can be declared either by using single or double quotes:
