"Python is a computer programming language created initially by Guido Van Rossum, who released it to the world as an "Open Source" "Free"program. It has since then been progressively improved by the contributions of hundreds of computer programmers around the world. The Python package can be downloaded gratis from the internet for every major computing platform in existence. It can be used and even modified for just about any purpose.

"Why Python?

"There are many computer programming languages in existence. They all have different advantages and disadvantages. The brain of a computer is its processor. No processor understands English. The processor needs to receive input in a format that it understands. Most processors are made to understand commands formatted as a series of zeros "0" and ones "1". This format is called binary. It is possible to write programs by hand using this format of zeros and ones, but it is very difficult, time consuming, and error prone. That is why computer programming languages have been invented.

"Programming languages are frequently categorized as "low level" or "high level". Low level languages were the first ones to appear. They simplified the process of writing instructions to the computer by allowing the use of normal words to be used in writing the program. A translator program, a "compiler", translates the program's instructions into a binary file that can then be understood by the processor. However, low level programming languages are still quite difficult to master. They force the programmer to understand the way the computer works internally."
