Binary Search in Python (Recursive and Iterative)

Searching for an element’s presence in a list is usually done using linear search and binary search. Linear search is time-consuming and memory expensive but is the simplest way to search for an element. On the other hand, Binary search is effective mainly due to the reduction of list dimension with each recursive function call or iteration. A practical implementation of binary search is autocompletion.

Python Binary Search Algorithm:

The objective of this project is to create a simple python program to implement binary search. It can be implemented in two ways: recursive (function calls) and iterative.

Project Prerequisites:

The project uses loops and functions to implement the search function. Hence good knowledge of python loops and function calls is sufficient to understand the code flow.

Lambda, Map, Filter functions in python

Welcome to my Blog, In this article, we will learn python lambda function, Map function, and filter function.

Lambda function in python: Lambda is a one line anonymous function and lambda takes any number of arguments but can only have one expression and python lambda syntax is

Syntax: x = lambda arguments : expression

Now i will show you some python lambda function examples:

Recursion And Iteration In Python Programming

Acomputer program consists of line-by-line instructions. The computer performs those instructions line-by-line. However, some instructions may be repetitive with a common pattern. Recursion or iteration helps one to write a few lines of codes to perform such repetitive tasks. Suppose a Python list with five-string elements. We wish to print the elements one in a line. This operation needs five lines of codes.

 flowers = ['lily', 'tulip', 'rose', 'lavender', 'dandelion'] 
 print(flowers[0])
 print(flowers[1])
 print(flowers[2])
 print(flowers[3])
 print(flowers[4]) 

Output:

It can be observed that the five lines of codes follow the same pattern. The only difference in each line is the index of the list elements. What if this list contains 100 or 1000 elements? Coding will become a tedious task. These kinds of problems are resolved through either iteration or recursion. Here, the iterative form of the above codes is as follows.

 for flower in flowers:
   print(flower) 

Output:

These two lines are sufficient to achieve the task even if the list contains a million elements!

Python Tricks Every Developer Should Know

Python is awesome, it’s one of the easiest languages with simple and intuitive syntax but wait, have you ever thought that there might ways to write your python code simpler?

In this tutorial, you’re going to learn a variety of Python tricks that you can use to write your Python code in a more readable and efficient way like a pro.

Let’s get started

Swapping value in Python

Instead of creating a temporary variable to hold the value of the one while swapping, you can do this instead

>>> FirstName = "kalebu"
>>> LastName = "Jordan"
>>> FirstName, LastName = LastName, FirstName 
>>> print(FirstName, LastName)
('Jordan', 'kalebu')
