Let’s discuss a shorthand which can be … ... #34 Find First and Last Position of Element in Sorted Array. here, all the elements in the array are consecutive as they are in increasing order ie, 64,65,66,67,68. Python NumPy Array Object Exercises, Practice and Solution: Write a NumPy program to create a new array which is the average of every consecutive triplet of elements of a given array. array contains consecutive elements. If you enter the list [1,2,3,6,7,10], for example, it would return:. Sometimes, while working with Python list, we can have a problem in which we need to get the consecutive elements count remaining( including current ), to make certain decisions beforehand. The following is a function that I wrote to display page numbers as they appear in books. We have to find the length of the longest consecutive elements sequence. E.g.
