Blockchain Smart Contract Theory Behind

The smart contract in Blockchain is a kind of software application that works without human intervention based on the transaction logs and provide a solution to the user request. 
I want to share the back end mechanism in the Smart Contract of Blockchain.

Smart Contract Mechanism What is Smart ContractA smart contract is a protocol which can auto-execute, facilitate, verify, or enforce the negotiation of a contract.Agreement between two parties you can say as a contract.Incorporating the rules of the physical contract into the computing world, you can say as a smart contractBlockchain supports you to create smart contracts.Smart Contracts are self-executing programs which run on the blockchain and are capable of enforcing rulesUsing Blockchain as a platform and making an agreement or contract between more than two parties, you can say as Smart Contract.Traditional Markets  4 Top Benefits of Smart ContractCurrently, smart contracts are being used only in Crypto CurrenciesNow Smart Contra…

Python top two ideas you need to Compare Strings

In Python, you can compare two strings how you would do on numbers. Python is stricter on string comparison. It identifies any small differences in strings. So Python is case sensitive while comparing it checks for identical ones. 

  
Python follow-suite other languages. It compares strings for exact equals. Else, treat them as different strings.

Python String Comparison 

  • Extra spaces
  • Uppercase or Lowercase

#1 Example

>>> a = "Virginia"
>>> b = "virginia"
>>> a == b False 

The strings a and b are looking similar. But there is case sensitive difference. Python checks for extra white spaces as well as Upper or Lowe case letters.

#2 Example

>>> greet1 = "Hello "
>>> greet2 = "Hello"
>>> greet1  == greet2 False

The greet1 has space at the end whereas greet2 does not. Python looks at whitespace when comparing strings, so the two aren’t considered equal.
