It helps manipulate and analyze stored data. “Pandas” stands for Panel Data, which means an Econometrics from Multidimensional data. According to the official pandas documentation, it is “a Python package providing fast, flexible, and expressive data structures designed to make working with “relational” or “labeled” data both easy and intuitive.

In simple words, iterator is an object that can be iterated upon. They contain more than one data in it. Commonly used Python iterators are list, tuple and dictionary. An iterator will return data from that object, one item at a time. Any Python iterator  must implement two methods: The __iter__ method which returns the iterator object  The __next__ method which return the next value for the iterable. How Does Iteration… Read More »What are Iterators in Python

Problem Statement Write a function that reverse a string. Input string will be given as an array of characters char[]. Can you to it without allocating extra space for another array? Hint: You must do this by modifying the input array in-place with O(1) extra memory. You may assume that all the characters comprise of printable ascii character. Examples: Example 1: Example 2: Let’s see how to solve this question.… Read More »Optimized way to Reverse a String | Leetcode Challenge #344

Longest repeated substring problem is a problem of finding the longest substring that occurs at least twice in a given string. This is also one of the important interview questions. Problem Statement Given a string S, consider all duplicated substrings: (contiguous) substrings of S that occur more than once.  (The occurrences may overlap.) Return any duplicated substring that has the longest possible length.  (If S does not have a duplicated substring, the answer is "".) Example 1: Input: “banana”, Output: “ana” Example… Read More »Longest Repeated Substring Problem

Slicing is extraction of a part of a sequence like list, tuple, string. It can fetch multiple elements with a single statement. It does not remove the values from the iterable; instead makes a new object with the desired elements. Syntax start – Starting integer where the slicing of the object starts. Default to None if not provided.  end– Integer until which the slicing takes place. The slicing ends at index end – 1… Read More »A Complete Guide on List Slicing and slice() Method of Python

The index() method is used to find the position of a particular element in the Python List. Since it is a method of list class, it’s called using a .(dot) operator on list. It checks every element from the starting of the list until it finds a match. The index in python is start from 0. Syntax Method returns zero-based index element in the list whose value is equal to x. … Read More »How to Get Index of an Element in Python List

You might have noticed some times Microsoft Word automatically converts text into required fraction you need. But for most of the case, Word doesn’t do this magical conversion. It happens because, Ms Word has autocorrect feature enabled by default that convert commonly used fractions like 1/2, 1/4 and 3/4 to fraction characters like , and . However using this feature you can convert only a handful of fraction automatically. It… Read More »How to Type Fraction in Word: Tips and Tricks to Write Fractions
