I do aware of a quick solution by iterating the list in a for loop and comparing current and next items for equality until it reaches the end. So, if the array were. Assume that we have the following pandas dataframe: What I want to get is the number of consecutive values in col1 and length of these consecutive values and the difference between the last element's start and first element's start: Break col1 into sub-groups of consecutive strings. Should the alternative hypothesis always be the research hypothesis? And then we put a.shift (-1) != a in loc to return a data frame without the consecutive duplicate values. You can accomplish this using the pandas shift () function, which can be used to get the very next element, like so: data = data.loc [data.shift () != data] What this does is for every row in the DataFrame, it compares it to the next row. rightBarExploreMoreList!=""&&($(".right-bar-explore-more").css("visibility","visible"),$(".right-bar-explore-more .rightbar-sticky-ul").html(rightBarExploreMoreList)), Python groupby method to remove all consecutive duplicates, Python - Remove alternate consecutive duplicates, Python | Consecutive duplicates all elements deletion in list, Python - Ways to print longest consecutive list without considering duplicates element, Python | Sort given list by frequency and remove duplicates, Python | Remove duplicates from nested list, Python | Remove duplicates based on Kth element tuple list, Python | Remove all duplicates and permutations in nested list, Python - Ways to remove duplicates from list.

The problem with shift() is that it creates NaN as the first value and removes the last value from the column To detect consecutive runs in the series, we first detect the turning points by looking at the locations where difference with previous entry isn't 0. If you are still not quite sure what is the problem were trying to solve, dont worry, you will understand by the sample data that is generated as follows: In the screenshot, the green lines split the groups that we expected. In this, we iterate and check for the next element, if equal to current, we add in result list, then it is converted to set to get distinct elements. Again, this approach will require the list to be complete the same for it to be considered a duplicate. Making statements based on opinion; back them up with references or personal experience.

Can someone please tell me what is written on this score? This is because the for loop iterates through the list once, and the rest of the operations (checking if the current element is the same as the last seen element and appending the element to the result list) are constant time operations.Auxiliary space: O(n), because it creates a new list to store the elements after removing consecutive duplicates, and the size of this list is equal to the number of elements in the input list. Since it's never sorted you have to iterate through it, so the complexity should be linear O(n), I found this one, quite simillar to the otherone posted, but it should work.
