In this article we show how to encode and decode data in Python. str.encode(encoding='utf-8', errors='strict') The str.encode function encodes the string value to the bytes type. The encoding defaults to 'utf-8'. bytes.decode(encoding='utf-8', errors='strict') The bytes.decode ...
expressions, check out How to Use Generators and yield in Python. Map The built-in functionmap() takes a function as a first argument and applies it to each of the elements of its second, an iterable. Examples of iterables are strings, lists, and tuples. For more information on...
I've usedSEPARATORhere to separate the data fields; it is just a junk message, we can just usesend()twice, but we may not want to do that anyway.encode()function encodes the string we passed to'utf-8'encoding (that's necessary). Now we need to send the file, and as we are send...
Next, you will use thedecode()function to convert the byte string back into a string. Thedecode()function accepts the encoding type as an argument. It is also worth mentioning that thedecode()function can only decode the byte string, which is specified by using the letterbat the beginning ...
Python has an in-built function called open() to open a file. It takes a minimum of one argument as mentioned in the below syntax. The open method returns a file object which is used to access the write, read and other in-built methods. ...

". You can also encrypt and decrypt a file based on a simple and logical algorithm. But with the help of the Python cryptography library, you do not need to implement an algorithm of your own. You can simply use its generate_key(), encrypt, and decrypt function for file ciphering....
Create a Main Function: The primary role will be to create the blockchain, mine for a few additional blocks, and then validate the blockchain. This function checks the accuracy and functionality of your implementation. Here is an example of a simple blockchain in Python: import hashlib import...
