What is Unidecode? Unidecode is a Python module that helps convert unidecode text into plain ASCII characters. This is mostly used when the text contains special characters or non-English characters, and you need to simplify it. For example, it converts "kožušček" to "kozuscek", "北京" to "Bei Jing", and "naïve" to "naive". This module is popularly used to simplify for processing or display of user-generated content and international data [multi-lingual]. Installing Python Unidecode Module To install unidecode or any other Python module, you need pip installed(Python package manager). If you have Python 2 >=2.7.9 or Python 3 ... Read More

Separate tuple and list data types are provided because both have different roles. Tuples are immutable, whereas lists are mutable. That means Lists can be modified, whereas Tuple cannot. Tuples are sequences, just like lists. The differences between tuples and lists are, the tuples cannot be changed unlike lists and tuples use parentheses, whereas lists use square brackets. Let’s see how Lists and Tuples are created. Creating a Basic Tuple We will begin the code by creating a basic tuple with integer elements. Next, specify the topics as advanced concepts like tuples nested within tuples. The provided code initializes a ... Read More

Lists of Tuples in Python A tuple is a built-in Python data structure for storing multiple items in a single variable. While both tuples and lists can organize ordered collections of items, tuples are immutable, whereas lists are mutable. A list can store heterogeneous values, including various types of data such as integers, floating-point numbers, strings, and more. A list of tuples refers to tuples encapsulated within a list. Comparing Lists of Tuples The '==' operator is used to compare two iterables and determine if they are equal. It is used to check whether two lists are equal. Therefore, we ... Read More

In this problem, we are given a binary string, and we have to check if all the 1s present in the binary string are at an equivalent distance from each other. Example 1 Input: binaryString = "10101010" Output: Yes Explanation The positions of 1s in the given string are 1, 3, 5, and 7.Here, the difference between consecutive 1s is 2 (as 7-5 equals 5-3 equals 3-1), so all 1s are at an equivalent distance from each other. Example 2 Input: binaryString = ... Read More
