What is the difference between list.sort() and sorted() in Python?
Python provides two ways to sort a list, the built-in list method list.sort() and the built-in function sorted(). Although both will sort the elements of a list, if used incorrectly they can produce unexpected or undesired results.
Differences and similarities
The primary difference between the two is that list.sort() will sort the list in-place, mutating its indexes and returning None, whereas sorted() will return a new sorted list leaving the original list unchanged. Another difference is that sorted() accepts any iterable while list.sort() is a method of the list class and can only be used with lists.
Both list.sort() and sorted() have the same key and reverse optional arguments and can be called on each list element prior to making comparisons.
When to use each one:
list.sort() should be used whenever mutating the list is intended and retrieving the original order of the elements is not desired. On the other hand, sorted() should be used when the object to be sorted is an iterable (e.g. list, tuple, dictionary, string) and the desired outcome is a sorted list containing all elements.

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. “Once 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,” says Stacey Harris, consultant for Pelicoin, a network of cryptocurrency ATMs. Blockchain is decentralized, which means it’s not controlled by any one organization. “It’s like a Google Doc that anyone can work on,” says Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax. “Nobody owns it, but anyone who has a link can contribute to it. And as different people update it, your copy also gets updated.”
The STAR Market, as is implied by the name, is heavily geared toward smaller innovative tech companies, in particular those engaged in strategically important fields, such as biopharmaceuticals, 5G technology, semiconductors, and new energy. The STAR Market currently has 340 listed securities. The STAR Market is seen as important for China’s high-tech and emerging industries, providing a space for smaller companies to raise capital in China. This is especially significant for technology companies that may be viewed with suspicion on overseas stock exchanges.
