In the last tutorial we learnt about while loops. Lets take a look at for loops in this tutorial.

For Loops

For loops are used to iterate over a sequence. The syntax being :

In this tutorial we will learn how to use while loops in Python.

What is a loop?

Loops are generally a block of code which you want to repeat a fixed number of times or until a certain condition is met. Python has two loop commands. They are :

• while loops
• for loops

In this tutorial we will cover the basic characteristics of Python dictionaries and learn how to access and manage dictionary data.

What is a Dictionary?

Dictionary is a collection of object that are unordered and changeable but works with keys and values instead of indexes. Dictionaries are similar to lists. The main difference between…

In this tutorial we will see how to write functions in python.

What are Functions?

Functions are blocks (or lines) of code which allowing us to order our code, make it more readable, and reuse it. We can pass data, known as parameters, into a function. …

Introduction

As discussed in the previous tutorial on Map functions, Filter, and Reduce are typical examples of functional programming. They allow us to write simpler, shorter code, without bothering about loops and branching.

Let us see how to use these functions in this tutorial.

Filter Function

Filter function returns boolean values (which is…

Introduction

Map, Filter, and Reduce are typical examples of functional programming. They allow us to write simpler, shorter code, without bothering about loops and branching.

In this tutorial we will see how to use the built-in map and filter functions in python.

Map comes built-in with Python (in the __builtins__ module)…

In this Tutorial, we will learn invaluable skills that will form the foundation of our data processing work. Before we can apply machine learning algorithms or do different analyses on our data, we must clean and transform our data into suitable formats. Such initial data wrangling processes are often referred…
