1. Introduction
What is Python?

Python is a popular programming language. It was created by Guido van
Rossum, and released in 1991.

It is used for:

• web development (server-side),
• software development,
• mathematics,
• system scripting.

What can Python do?

• 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
files.
• Python can be used to handle big data and perform complex
mathematics.
• Python can be used for rapid prototyping, or for production-ready
software development.

Why Python?

• 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 with fewer
lines than some other programming languages.
• Python runs on an interpreter system, meaning that code can be
executed as soon as it is written. This means that prototyping can be
very quick.
• Python can be treated in a procedural way, an object-oriented way or a
functional way.

Good to know

• 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 Syntax compared to other programming languages

• Python was designed for readability, and has some similarities to the
English language with influence from mathematics.
• Python uses new lines to complete a command, as opposed to other
programming languages which often use semicolons or parentheses.
• Python relies on indentation, using whitespace, to define scope; such
as the scope of loops, functions and classes. Other programming
languages often use curly-brackets for this purpose.

2. Getting User Input and Concatenation
The input() function
• Used to get user input
• Returns a string value
• Can be concatenated with other strings
Concatenation
• Joining two or more strings together
• Use the + operator for concatenation
Example
name = input("What is your name? ")
print("Hello, " + name)
ValueError
• Occurs when an operation or function receives a value of an inappropriate
type
• Example: Trying to convert a string to an integer using the int() function
and the string does not contain a number
age = int(input("What is your age? "))
Displaying Results
• Use the print() function
• Accepts any number of arguments
• Separate arguments with commas
