Python: Built-in Functions vs. For & If Loops – 5 Programs Explained

Image
Python’s built-in functions make coding fast and efficient. But understanding how they work under the hood is crucial to mastering Python. This post shows five Python tasks, each implemented in two ways: Using built-in functions Using for loops and if statements ✅ 1. Sum of a List ✅ Using Built-in Function: numbers = [ 10 , 20 , 30 , 40 ] total = sum (numbers) print ( "Sum:" , total) 🔁 Using For Loop: numbers = [ 10 , 20 , 30 , 40 ] total = 0 for num in numbers: total += num print ( "Sum:" , total) ✅ 2. Find Maximum Value ✅ Using Built-in Function: values = [ 3 , 18 , 7 , 24 , 11 ] maximum = max (values) print ( "Max:" , maximum) 🔁 Using For and If: values = [ 3 , 18 , 7 , 24 , 11 ] maximum = values[ 0 ] for val in values: if val > maximum: maximum = val print ( "Max:" , maximum) ✅ 3. Count Vowels in a String ✅ Using Built-ins: text = "hello world" vowel_count = sum ( 1 for ch in text if ch i...

According to Investopedia - Originally developed as the accounting method for the virtual currency Bitcoin , blockchains – which use what's known as distributed ledger technology (DLT) – are appearing in a variety of commercial applications today. Distributed Ledger 1 - What is the Current Trend All the transactions currently can be edited by the server owners. They have full control to change the transaction details. The current trend is either centralized or decentralized. 2- Distributed Trend No one can edit the transaction details. It is transparent to all stakeholders.

How to Use Blockchain in Internet of Things and Real Applications

Image
You do not need a central authority in the blockchain. The distributed nature of records makes the records visible to all the parties. Encrypted blocks link to each other. You cannot manipulate the stored records in the blockchain.   Why the peer-to-peer network and the absence of a central authority Peer to peer network makes secure and transparent transactions. The data in the blocks are encrypted. The distributed nature is the main reason for not having central authority in the blockchain. Blockchain in IoT There are already blockchain applications in the context of the Internet of Things and some vendors have specific solutions to enable the use of blockchain for IoT too, among others increase trust, save costs and speed up transactions.  IBM is a frontrunner , although several vendors and industry initiatives have been launched with new solutions and actual deployments.

Tokenization: Vault based Vs Vault-less

Image
Tokenization means generating a random number as an alternative for a Credit card (PAN) number. The random number can be Numeric/Non-numeric. It is in such a format that others cannot decode it.    *** The popular tokenization server is the Vault server. It generates a random Token for each transaction customer made at Merchant outlets. You can find how card numbers are masked with junk characters in the pdf provided. Here is the  Visa Security Tokenization Pdf. Two Top Tokenization Servers. Vault based server Vault-less server What is Tokenization? 1. Vault based server It stores a  Card number (PAN) and a Token  in a Table of the Teradata database as Key and value pairs. Due to the growing volume of transactions, the handling of the database became a big challenge for acquirers.  For each transaction, the vault server stores a record. That row contains both the Credit card number and its Token. When you use the same card multiple times, it gener...

Here are the disadvantages of Blockchain. Below, you will find the list of these. Blockchain Disadvantages Lack of privacy Loss of personal responsibility Loss of jobs Reintermediation 1. Lack of Privacy Public blockchains do not hide any of their data. Instead, everyone can read the complete history of transactions. This level of transparency is frightening for those who want to protect their privacy. These concerns are understandable when considering the level at which personal data are already collected and utilized by large corporations or intelligence agencies. 2. Loss of Responsibility Loss of personal responsibility is often considered a consequence of disintermediation. Intermediaries not only bring different parties of a contract together but may also provide guarantees. They offer reconciliation in cases when transactions do not work out as intended, and they are also obliged to take responsibility for their actions.
