๐ A scope is a block of code where an object in Python remains relevant.Each and every object of python functions within its respective scope.As Namespaces uniquely identify all the objects inside a program but these namespaces also have a scope defined for them where you could use their objects without any prefix. It defines the accessibility and the lifetime of a variable.
Letโs have a look on scope created as the time of code execution:
๐A local scope refers to the local objects included in the current function.
๐A global scope refers to the objects that are available throughout execution of the code.
๐A module-level scope refers to the global objects that are associated with the current module in the program.
๐An outermost scope refers to all the available built-in names callable in the program.

Bitcoin is built on a distributed digital record called a blockchain. As the name implies, blockchain is a linked body of data, made up of units called blocks that contain information about each and every transaction, including date and time, total value, buyer and seller, and a unique identifying code for each exchange. Entries are strung together in chronological order, creating a digital chain of blocks. โOnce a block is added to the blockchain, it becomes accessible to anyone who wishes to view it, acting as a public ledger of cryptocurrency transactions,โ says Stacey Harris, consultant for Pelicoin, a network of cryptocurrency ATMs. Blockchain is decentralized, which means itโs not controlled by any one organization. โItโs like a Google Doc that anyone can work on,โ says Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax. โNobody owns it, but anyone who has a link can contribute to it. And as different people update it, your copy also gets updated.โ
What is Telegram?
Telegram is a cloud-based instant messaging service that has been making rounds as a popular option for those who wish to keep their messages secure. Telegram boasts a collection of different features, but itโs best known for its ability to secure messages and media by encrypting them during transit; this prevents third-parties from snooping on messages easily. Letโs take a look at what Telegram can do and why you might want to use it.
