Which language is dynamically typed?

The correct answer is Python because it is considered a dynamically typed language. In dynamically typed languages, variable types are determined at runtime rather than at compile time. This means that you do not need to explicitly declare the data type of a variable when you assign a value to it; the interpreter infers the type based on the value assigned. This feature allows for more flexibility in coding, as data types can change as the program runs.

For example, in Python, you can assign an integer to a variable and later assign a string to the same variable without any type error. This flexibility is a characteristic trait of dynamically typed languages, making them often easier and faster to write, though it can also lead to runtime errors if not managed properly.

In contrast, C++ and Java are statically typed languages, where variable types must be declared before use and are checked at compile time. This means that once a variable is defined with a specific type in these languages, it cannot hold a value of a different type without explicit conversion. Ruby, while it has some similarities with Python in terms of dynamic typing, is often discussed separately due to its own characteristics and patterns. However, in this context, Python is the best example of a dynamically typed language.
