Dynamic typing is a feature in programming languages where the type of a variable is determined at runtime, rather than at compile time. This means that you can assign different types of values to the same variable throughout the program. For example, in a language like Python, you can start with a variable holding an integer and later change it to a string without any errors. This flexibility allows for quicker coding and easier experimentation, as you don’t need to declare variable types explicitly. However, it can also lead to potential errors if a variable is used inappropriately later in the code, making debugging a bit more challenging.
