“a” is immutable, and is being declared here. For example, you can create an object and then add functions to it, giving it the desired behavior, without a complex inheritance structure. Type Checking may occur either at compile-time (a static check) or at run-time(dynamic check). Ultimately, it comes down to personal preference and the kinds of tools that you like to use.Personally, I have a preference for dynamically typed languages because I hate to wait for the compiler when I’m debugging. Some of the popular dynamic typed programming languages include Python, JavaScript, Perl, Ruby, and Lua.Another key difference between static vs dynamic programming languages is that one is compiled while another one is interpreted.
If a language specification requires its typing rules strongly (i.e., more or less allowing only those automatic type conversions that do not lose information), one can refer to the process as Strongly typed, if not, as Weaklytyped.

There are many articles looking at ‘The previous section highlights a hugh difference in performance potential between dynamic code with Python and and Static typed code with Kotlin. If system is written in Python, then a second language is needed for these use cases.The special usage cases are just that: special. As a programmer, you don’t have to define the variables before they are put into use. Maybe this is related to my particular debugging style; either way, it’s the point that has the biggest impact on my productivity. A statically typed programming language is one which forces you to associate every variable with a data-type provided by the language when they are first declared and after that the values assigned to those variables are constrained by the values accepted by its data-type. This is because these languages have the full knowledge of types. This is because it allows variables to change types. This is why most established enterprises use Java, C++, and C#. In dynamic environments every instruction requires more runtime checking with a … In a short, recently written program, the answer is most often “yes”. Consider a case where the HtmlElement is a text input box, and the goal is to retrieve the value in the text box as entered by the user. I also covered Strongly-typed and Weakly-typed languages.Just as the assumption that all Strongly-typed languages are Statically-typed, not all Weakly-typed languages are Dynamically-typed; PHP is a dynamically-typed language, but C — also a weakly-typed language — is indeed statically-typed. In the second line, we tried attempting to add 10 (an int) to a variable of str type. This is a programmer should impose these restrictions on themselves, and in fact, programmers do generally impose these restrictions on themselves. If a program is slow there are two possible reasons:Application code is not really impacted by being written in Python. So, after compilation the compiler will have guarantees about the shape of data structures, the existence of methods etc. The compiler uses the configuration to produce the program code, which is then available to be run. For dynamically typed programming languages, types are checked during the execution of the code. A variable should not change type- without a really good reason. Types are potentially completely fluid.With statically typed languages, the types themselves are defined at compile time. With Kotlin, those extra keypresses and thinking things through are minimised, but they are still present. Statically typed languages have better performance at run-time intrinsically due to not needing to check types dynamically while executing (it checks before running). Before we proceed to dissect the differences between these two types of programming languages, let’s find out the meaning of the term “typed”. Examples of statically typed languages are :- Java, C, C… Despite that huge difference in potential,  the reality is that applications in Python are usuallyThe performance limitations discussed above, are even more significant in terms of code readabiliy that performance. For eg — type error could be a situation where an operation is performed on a data of type integer with the intent that it is a float, or even something such as adding a string and an integer togetherDespite of the fact that in many languages both strings and integers can make use of the + operator, this would often result in a type error because this expression is usually not meant to handle multiple data types.When a program is considered not to be type-safe, there is no single standard course of action that happens upon encountering a type error. All actual elements are subclasses of HtmlElement, and have a variety of attributes become the base class. Additional code can even create extension functions into that table in the compiler, which at least give the impression of extending a type, but again, this extension made to the table used by the compiler.
So all of the declarations have been applied prior to the first line of the program being run, and modifying those declarations is no longer possible.Every instance of a type is guaranteed to have the set of attributes described in the type, and that will not vary throughout the entire program. Working with truely dynamic classes is generally a complete pain and very hard to follow.In fact, Python tools such as PyCharm warn developers who making their types dynamic, by creating instance attributes in any method beyond To implement such dynamic singletion objects in a static language, the best approach is to have attributes stored in a collection. Typed in this context has Knowing the difference between them will help you to make the right choice when you want to build advanced systems. The last 5% you need dependent typing for and it's much more complicated, but that's still a statically typed system. In this article, we are going to look at the difference between static and dynamically typed programming languages.First things first. In a short program, at the time of writing, the programmers knows all of these things and writing them down is an overhead.
