 What is the Python?

     Python is a high-level, interpreted programming language that is object-oriented and has dynamic semantics. It is very appealing for Rapid Application Development because of its high-level built-in data structures, dynamic typing, and dynamic binding. It can also be used as a scripting or glue language to connect components that already exist. Python's basic, simple to learn grammar stresses clarity and accordingly decreases the expense of program upkeep. Python's support for modules and packages encourages code reuse and program modularity. For all of the major platforms, the Python interpreter and the extensive standard library are free to distribute in binary or source form.

    Programmers frequently fall in love with Python due to its increased productivity. The edit, test, and debug cycle is extremely quick because there is no compilation step. Programming in Python is simple: A segmentation fault will never be caused by a bug or bad input. Instead, an exception is raised when the interpreter finds an error. The interpreter prints a stack trace when the program does not catch the exception. Setting breakpoints, stepping through the code one line at a time, inspecting local and global variables, evaluating arbitrary expressions, and other capabilities are all made possible by a source level debugger. The fact that the debugger was written in Python itself demonstrates the introspective power of Python. On the other hand, adding a few print statements to the source code is frequently the quickest way to debug a program: This easy method is very effective due to the quick edit, test, and debug cycle.

DATA TYPES IN PYTHON

·        Python consists of Three Data Types

 

  

 

 

·       Numbers

·        There are three Types of Numbers in Python

 

·       Integers   Numbers

Ø In simple sense whole numbers are called integers numbers

           Example :  2, 10, 22

·       Floating Numbers

Ø Decimal Numbers either positive or negative are called Floating Numbers.

Example: 2.1 4.5 -7.8

 

·       Complex Numbers

Ø Complex Numbers refer to consisting of  real and  imaginary numbers .

 Example : 5 & 5k

      Here 5 is a real number and k is an imaginary number.

 

 

Strings

Booleans

Booleans data types are used to choose between two values –true and false. The value depends upon expression of data.

 Example :  Return the Boolean value of 1:

 If x=bool(1)

Value=True

 

Value of an object will be false if the expression is empty

Example: Return the Boolean value of {}

 If X=bool({})

 Value = False

                      Understanding     Crypt currency    

                                                                           Dr. Umakanta Hazarika            

         Introduction                                         
      Crypto currency is a virtual form of money that is surprisingly guarded by cryptography or encryption approaches, making it almost difficult to counterfeit. Those virtual currencies are intended to feature as a type of exchange. In general, no country's  reputable government troubles crypto currencies. Crypto currency networks are protected from any supervision by governmental regulatory authorities due to their decentralized nature. Virtual currency called crypto currency is decentralized, based totally on block chain era, and encrypted. Block chain, decentralization, and cryptography are the first three standards that one ought to recognize that allows you to apprehend crypto currencies.

  Meaning of Terminologies – Blockchain, Decentralization and Cryptography

  In easy phrases, blockchain in the context of crypto forex is a digital ledger whose access is sent among authorized users. These ledger records transactions related to a number of assets, like money, residence, or maybe highbrow belongings. The get right of entry to be shared between its customers and any information shared is obvious, immediate, and “immutable”. Immutable means something   that blockschain records is there for right and cannot be modified or tampered with – even by an administrator. Centralized money refers to the normal money that we use, that is governed through authorities just like the Reserve bank of India. Decentralization in crypto currency manner there's no similar authority that can be held responsible for supervising the upward thrust and fall of a selected crypto   forex. This has many blessings over centralized cash. Alternatively, cryptography is the method that secures information from unauthorized get admission to by means of the use of encryption strategies. Maximum of the claims that blockchain makes, like privateness and immutability, are enabled through cryptography. The roots of crypto currency generation may be traced again to the Nineteen Eighties with the discovery of what's called a “blinding set of rules”. The algorithm is all approximately comfortable and immutable virtual transactions. It remains fundamental to the contemporary-day virtual foreign money. The underlying block chain technology is these days utilized in banking, insurance, and different business sectors. growing at a compounded annual growth fee of 12.8% in view that 2021, the crypto currency market is anticipated to attain $4.ninety four billion via 2030, way to the want to improve the efficiency of these days’  payment systems, upward thrust in international remittances and accelerated want to relaxed information.

How does it  work ?

Cryptocurrencies aren't controlled by way of the government or central regulatory government. As an  idea, cryptocurrency works out of doors of the banking device the usage of distinctive manufacturers or forms of cash – Bitcoin being the essential participant.

·         Mining

   Crypto currencies (that are absolutely digital) are generated through a manner referred to as “mining”. that is a complex procedure. Basically, miners are required to resolve sure mathematical puzzles over particularly equipped pc structures to be rewarded with bit coins in trade.  In a great global, it'd take a person simply 10 mines to mine one bit coin, but in reality, the process takes a predicted 30 days.

·        shopping for, selling, and storing

users nowadays can purchase crypto currencies from principal exchanges, brokers, and character forex owners or sell it to them. Exchanges or structures like Coin base are the very best ways to buy or promote crypto currencies. Once bought, crypto currencies can be stored in digital wallets. Digital wallets can be “warm” or “cold”. Warm means the pockets is connected to the internet, which makes it smooth to transact, but susceptible to thefts and frauds. Bloodless storage, then again, is safer however makes it more difficult to transact.

·         Transacting or investing

  Crypto currencies like Bit coins may be easily transferred from one digital wallet to any other, the use of simplest a Smartphone. After you own them, your selections are to:

a) Use them to shop for items or offerings

b) Change in them

c) Trade them for coins

   In case you are using Bit coin for purchases, the very best manner to do that is thru debit-card-type transactions. you could also use those debit playing cards to withdraw cash, similar to at an ATM. converting crypto currency to cash is likewise feasible the usage of banking debts or peer-to-peer transactions.

Typology   of Crypto currencies

There are tens of lots of crypto currencies available nowadays with the discern pegged at 10,000 in 2022. major crypto currencies encompass the subsequent:

·        Bitcoin

    Bitcoin is the sector’s first extensively ordinary shape of cryptocurrency. Bitcoin is so popular, there was a time when its call was synonymous with cryptocurrency. but capability investors need to recognize bit coins have grow to be very costly. In 2021, the cost of 1 Bitcoin was $68,000. however the good information is, you don’t always have to shop for a whole coin, you could purchase smaller fractions of it.

·        Altcoin

   Altcoin is the time period used for any alternative virtual currency to bitcoin. The maximum popular on this atmosphere is Ethereum – one of the quickest-developing cryptocurrencies in the marketplace. there may be additionally a number different altcoins in the market today together with Luckyblock, Shiba Inu and Terra.

·        Crypto tokens

The idea of crypto cash vs tokens can be complicated to many. at the beginning glance, coins and tokens appear the equal. however, the 2 have many variations -

·        Cash may be mined, however tokens can't be mined.

·        Coins are linked to blockchains, tokens aren't.

     In terms of utility, they range in the form of product or service they permit customers to purchase.  

Why should we invest in cryptocurreny

There are many benefits to dealing in crypto currencies, and a truthful proportion of disadvantages as well. Here are the pinnacles  reasons that work in prefer of and towards crypto currencies.

Ø They’re non-public and cozy:

Ø The block chain era that fuels crypto currencies guarantees consumer anonymity.

Ø It also assures excessive degrees of safety through cryptography, which we mentioned earlier than.  

Ø They’re decentralized, immutable, and obvious: The complete gadget functions on shared possession, where data is available to all permission contributors and is tamper-proof.

Ø They’re a hedge in opposition to inflation:

Ø Crypto currency makes for a fantastic funding in instances of inflation. For example, investors frequently evaluate crypto currency to gold.

Ø One of the reasons at the back of this is that, just like gold, they're in limited supply, as there's a cap on mining any sort of crypto currency.
