Pandas is an open source, BSD-licensed library providing high-performance, easy-to-use data structures and data analysis tools for the Python programming language. Pandas introduces two new data types to Python: Series and DataFrame. Visit here to know about DataFrame and how to Create DataFrame. Sometimes data are available in millions or billions or even more than that. And you don’t want to see the whole data, you glimpse of data of what… Read More »Pandas Head() & Tail() Functions

Pandas is the most preferred Python library for data analysis. The reason is its core data structure called DataFrame, one of the two basic data structure of Pandas. It’s 2-dimensional labeled data structure with columns of potentially different types. DataFrame is a widely used data structure of Pandas and works with a two-dimensional array with labeled axes (rows and columns). Defined as a standard way to store data and has… Read More »Python Pandas DataFrame & Different Ways to Create Them

Pandas is a one of the most popular software library extension of Python. Wes McKinney designed it in 2008. 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
