What is a dynamically typed language?

A dynamically typed language is a programming language where the data type of a variable is determined at runtime rather than being explicitly declared beforehand. This means that the interpreter or compiler checks the type of a value when it's used, not when it's assigned.

Key characteristics of dynamically typed languages:

No explicit type declarations: You don't need to specify the data type of a variable when you declare it.
Flexible data types: Variables can change their data type during the execution of the program.
Runtime type checking: The interpreter or compiler checks the type of a value when it's used, which can lead to potential errors if the types are incompatible. (Python Course in Mumbai)
Examples of dynamically typed languages:

  • Python
  • JavaScript
  • Ruby
  • PHP

Advantages of dynamically typed languages:

Faster development: You can write code more quickly without worrying about type declarations.
More flexible: You can change the data type of a variable on the fly, which can be useful in certain situations. (Python Training in Mumbai)
Easier to learn: Dynamic typing can make programming easier for beginners.

Disadvantages of dynamically typed languages:

Potential runtime errors: If you use a variable incorrectly, you may not discover the error until the program is running. (Python Classes in Mumbai)
Reduced performance: Dynamic typing can sometimes lead to slower execution times compared to statically typed languages.

Dynamic typing offers flexibility and ease of use, but it can also introduce potential runtime errors. Whether a dynamically typed language is the right choice for a particular project depends on the specific requirements and trade-offs involved.
