Mastering flat_map in Python with List Comprehension

Image
Introduction In Python, when working with nested lists or iterables, one common challenge is flattening them into a single list while applying transformations. Many programming languages provide a built-in flatMap function, but Python does not have an explicit flat_map method. However, Python’s powerful list comprehensions offer an elegant way to achieve the same functionality. This article examines implementation behavior using Python’s list comprehensions and other methods. What is flat_map ? Functional programming  flatMap is a combination of map and flatten . It transforms the collection's element and flattens the resulting nested structure into a single sequence. For example, given a list of lists, flat_map applies a function to each sublist and returns a single flattened list. Example in a Functional Programming Language: List(List(1, 2), List(3, 4)).flatMap(x => x.map(_ * 2)) // Output: List(2, 4, 6, 8) Implementing flat_map in Python Using List Comprehension Python’...

How to use Blockchain on Cloud

Blockchain applications are growing in the financial world. Security is the main motto behind blockchain applications. You cannot tamper a record once created.


How to use Blockchain on Cloud

What is a platform
 

A platform is a place where you can develop applications.

Top Blockchain Cloud Platforms

The development needs to create a project and deploy it into production. So that the real use can feel by users at their end.

Ok...

Let us come to three popular cloud platforms that are highly used in Blockchain applications:
  1. HyperLedger
  2. IBM BlueMix
  3. Microsoft Azure

#1. HyperLedger

  • The Hyperledger project is led by Executive Director Brian Behlendorf, who has decades of experience dating back to the original Linux Foundation and Apache Foundation, as well as being a CTO of the World Economic Forum. So it's not surprising that Hyperledger has been well received. You can learn hyper Ledger here.

  • Many of the top business and industry leaders have joined the project, including Accenture, Cisco, Fujitsu Limited, IBM, Intel, J.P. Morgan, and Wells Fargo. It has also attracted many of the top blockchain organizations.

#2. IBM Bluemix

  • IBM is now offering blockchain technology that integrates with its traditional offerings, such as IBM Bluemix. Bluemix is an open-standards, cloud-based PaaS for building and managing applications.

  • IBM has integrated a blockchain stack from Hyperledger, which is part of the Lynx Foundation, and is establishing best practices in blockchain technology.

#3. Microsoft Azure


  • Ethereum is a Turing-complete blockchain framework for build applications. Microsoft aims to build more offerings based on blockchain technology and Hyperledger. It's also growing the Azure marketplace while transitioning to a portal for customers on Azure.
