Computer programming languages allow us to give instructions to a computer in a language the computer understands.
The diagram above shows how programming languages hide details from the user.
At the base of the diagram, we have the computer hardware.
The hardware refers to the part of the computer that we can see and touch.
To control a computer, we need to use a machine language. Each computer has it’s own machine language and programmers found it hectic to have to learn because it was in binary.
As time when on, the Assembly Language was developed. Assembly Language provided a symbolic representation of the machine code needed to program a given CPU architecture.
The real breakthrough in computer programming would start with the arrival of high level languages.
High level languages were closer to English and in addition to making the task of computer programming easier, they also opened the field to a lot more people.
The top four from that period in computing history are C, BASIC, FORTRAN and COBOL.
Applications running this languages are still in use today.
We will be learning the Python programming language.
According to the TIOBE Index as at January 2020, the Python programming language is the 3rd most popular programming language in the world.
Each language has it’s strength and weakness but for absolute beginners, I will give my reasons why recommend learning the Python programming language first.
When you are starting out on the journey of learning to code, you don’t want to deal with problems that occur while setting up your computer.
While learning Java at the University, one of the biggest issues we would run into was the setting of classpath.
The issue of classpath would stop many beginners dead in their tracks.
In Python, once you have installed the interpreter, you are ready to start programming.
In addition, the language is simple and readable. The commands in the language look like English.
Python is a general purpose language that caters to every use case that you can imagine.
It might not beat a specialized language in its domain but it will allow you get started in any domain.
The true secret weapon of the Python programming language is the community.
The versatility of the Python programming language is due to the libraries developed by the community.
As technology become more integrated with everyday life, learning how to program will become important in being a member of the society.
For absolute beginners, the Python programming language is great for starting because it is simple and easy to use.
