Everyone who has read the book or seen the film Da Vinci Code has heard about the Fibonacci sequence. The sequence looks a bit like this: In recent years a zero has been added to the front of the sequence, and it it this sequence I will be programming. The Fibinacci sequence can be defined …

Another good function which would come in handy for Zeller is a function to make sure the date which was inputted is valid and display a message if the program has encountered an invalid date. For this function I will be using my inArray function which I wrote in a previous post. I will utilise …

Something I am constantly wanting to do in a lot of programs is see if a value is in an array. For another function which I wish to write to add to the Zeller program this will come in handy. The basic algorithm looks like this: SET value TO RequiredValueSET array TO ArrayToSearchSET isIn TO …

We all remember factorals from school but to remind us what they are, a factoral is the product of all the positive integers less than or equal to the initial number(n): For example: Strangely 0!=1 there is a mathematical proof which states why but I will not be expanding on it here, I will however …

Now that we know that the algorithm works we can know build a solution We will start by adding code to perform the calculation for this we will need to import the Python math module so that we can use the built in floor function. We will also have to take into account the months …

Anyone that has studied secondary school mathematics knows what a prime number is but just to recap the definition of a prime number is any number which is only divisible by 1 and itself. 1 is however not a prime number as it is only divisible by itself, and other than 2 all prime numbers …

In my last post I wrote a program to print the Collatz Conjecture for a particular number. In this program I had to check if the number is odd or not(even). For my next program I will need to do this check again so I have decided to write a very short function to check …

In the This program just returns the value for a single value so we need to wirte an extra function to get the sequence: The code above adds the values in the sequence to an array and then prints simply prints the array to the screen, running the code above produces the following output: This …
