It is used in creating the anagrams, checking for permutations, or standardizing the input for consistent processing, for example, turning 'banana' into 'aaabnn'. In this article, we will explore how to sort the letters in a string alphabetically, this can be done by using the Python built-in function. Using Python sorted() Function The Python sorted() function is used to return a new sorted list from the items in the iterable object. The order of sorting can be set to either ascending ...
Read MoreHow to find the longest common substring from more than two strings in Python?
The substrings are the sequence of characters that appear within the string. While working with multiple strings, it is useful to find the longest common substring. There are various ways to find the longest common substring from more than two strings. one of the most common approach is using the dynamic programming. Let's dive into the article to learn more about this task. Using Dynamic Programming In this approach, we are going to use the dynamic programming (DP), Here we compare the strings pairwise (starting with first two strings), we find their longest common substring using a DP ...
Read MoreHow to do string concatenation without \'+\' operator in Python?
In this article, we are going to find out how to do string concatenation without the plus operator in Python. Generally, String concatenation is the process of joining two or more strings into one, and the common way to do this is by using the '+' operator. For example, writing "Welcome" + " " + "TP" results in the string "Welcome TP". But here we need to perform the concatenation without the '+' operator. For achieving this, Python provides alternative methods, which we will explore one by one. Using Python join() Method The first approach is ...
