Python 3.9: Here’s All About its Latest Features

With the upcoming of a new version of Python programming language, the development of web technology is clearly on the driver seat. The pre-beta release is already over and people are loving the new imminent version. Experts believe that this will be the game-changer as well as the major breakthrough in web technology. 

According to the reports, there will be many new features over the previous version. With the help of these exclusive features, the websites will get more impeccable designs. People are waiting for the release of the full version which will happen very soon. 

Details of all the Latest Features 

Python 3.9 is going to be released with a bunch of new features. Without further ado, let’s check them out and know the details. 

The Code Prediction 

Code and type prediction while typing? Exciting isn’t it? You can well understand that you don’t have to type many things. While starting code or a comment, it will automatically give you the results related to your statement. Choose your desired one from the following list. 

In addition to that, you also don’t have to specify the data types and its AI predictive algorithm will catch what’s going on in your mind. In the 3.5 version, you had to specify the datatype, but now things have changed. 

Dictionary Union Operators

Experts believe that with the help of sleek syntax, it will be people’s favourite feature in Python 3.9. When you want to merge any operator into one, you need to provide a data type named Union. The entire dictionary of all the Union operators will be present in the latest version. 

While merging, you will see that the update operator will place itself automatically. In addition to that, the dictionary will share the common key between the two data types. 

With the help of dictionary iterable, you will be able to update the dictionary by adding new key-value pairs of an iterable object. A list generator is one of the good examples of key-value pairs. 

Introducing New String Methods

A very useful feature in the new version of Python is the String method. You can use the updated string methods for eliminating prefixes and suffixes. Let’s say you want to print “Hello World”. And, you have to write the code Hello world.removeprefix(“He”). The result will be “llo world”. For removing the suffix you have to write Hello world.removesufffix(“ld”). The output will be “Hello wor”

The newly Introduced Python Parser 

The Python parser is a sort of out-of-sight change that will bring more significant changes in the future. Python is currently using the LL version 1 based grammar database. You can parse all the data with the help of LL version 1 parser. The parser actually parses the code from left to right and top to bottom.

Probable Issues of Python 3.9 

According to reports and analysis by experts, they are expecting that there might be some issues that can arise after the launch of the new version. First, you must know that Python 3.9 has LL version 1 based on grammar, not the actual LL(1). Some parts of this grammar database use a workaround. It can lead to the rise of unwanted complexities. 

The LL(1) grammar library has some limitations while working with Python’s latest syntax. In this case, you cannot implement and parse the code with the current running parser. If you try to do so, then it will show syntax errors. On the other hand, LL(1)breaks the left recursion in the parser. It actually means that the recursive syntax will take the syntax to an infinite loop. 

As the experts suggested that all of these factors will resist the progress of the upcoming Python version. To some extent, there is a high possibility of creating certain limitations in the evolution of the web programming language.
