Best Practices for Handling Duplicate Elements in Python Lists

Here are three awesome ways that you can use to remove duplicates in a list. These are helpful in resolving your data analytics solutions.  01. Using a Set Convert the list into a set , which automatically removes duplicates due to its unique element nature, and then convert the set back to a list. Solution: original_list = [2, 4, 6, 2, 8, 6, 10] unique_list = list(set(original_list)) 02. Using a Loop Iterate through the original list and append elements to a new list only if they haven't been added before. Solution: original_list = [2, 4, 6, 2, 8, 6, 10] unique_list = [] for item in original_list:     if item not in unique_list:         unique_list.append(item) 03. Using List Comprehension Create a new list using a list comprehension that includes only the elements not already present in the new list. Solution: original_list = [2, 4, 6, 2, 8, 6, 10] unique_list = [] [unique_list.append(item) for item in original_list if item not in unique_list] All three methods will result in uni

6 Top Solidity Interview Questions

Solidity is the prime language to write the logic for smart contracts in the Ethereum blockchain. These are selected interview questions refresh before you take an interview.

Solidity is one of the top programming language to use in Block chain. In this post added important interview questions for your reference.

Interview Questions on Solidity

1. What is Solidity?

A) Solidity is the main language that you can use to write programs in Blockchain, such as smart contracts.

2. Where the Solidity programs run in Ethereum?

A). Those will run in EVM. You can also call it an Ethereum Virtual Machine.

3. What kind of logic a Smart Contract can contain?

A contract in the sense of Solidity is a collection of code (its functions) and data (its state) that resides at a specific address on the Ethereum blockchain

4). Can the source code of smart contracts accessible to the outside world? 

A). No, it is not possible to access the source code to the network. Also, there is limited access to one smart contract logic to the other smart contract logic. Eve, file systems, and other processes cannot access the source code.

Actually, the code is sandboxed and you cannot access it.

5). How many accounts are present in Ethereum?

A). There are two - One is external and the other one is a contract account.

6). What is Remix?

A). This is an online platform to develop smart contracts. Here, you can use solidity programs and develop your own smart contracts.
