James Gosling:From a strategic point of view, they tend to more often be trouble free. And there are usually things you can do with immutables that you can't do with mutable things, such as cache the result. If you pass a string to a file open method, or if you pass a string to...

Python: Find the longest word in a string I'm preparing for an exam but I'm having difficulties with one past-paper question. Given a string containing a sentence, I want to find the longest word in that sentence and return that word and its ... ...
Sets are mutable that mean we can add, remove and repeat an element into it. It allows indexing and slicing like strings an element from a list by using different operators. name={"ahana","jacob","yana","ankush","umang"} Mixed set ? name= {1,"ahana",2, "jacob",3,"yana",4,...
In this case, you use@add_messagesto decorategreet(). This adds new functionality to the decorated function. Now when you callgreet(), instead of just printingHello, World!, your function prints two new messages. The use cases for Python decorators are varied. Here are some of them: ...
The syntax for accessing the elements of a list is the same as for accessing the characters of a string – the bracket operator ([ ]). The expression inside the brackets specifies the index. Unlike strings, lists are mutable. When the bracket operator appears on the left side of an assign...
has the same memory position. With this you don't waste memory declaring the same object multiple times. Because of a string is defined in many places if there was mutable a change to one will cause a change in the others, and no ones want that. That's why the strings...

As you can see in the snippet above, Python is relying on more than just the hash value of an object when using it as keys for a dictionary. Hash Values of Custom Classes We have seenbeforethat there are differences between mutable and immutable types in Python. Built-in immutable types ...
What this means is that Redis provides access to mutable data structures via a set of commands, which are sent using a server-client model with TCP sockets and a simple protocol. So different processes can query and modify the same data structures in a shared way. Data structures implemented...
