How do you declare a variable in Python?

In Python, a variable is declared by assigning a value to a name. This process involves creating a reference to the data stored in memory, which can then be utilized within the program. The syntax is straightforward; you simply write the variable name followed by an equals sign and the value you want to assign. For example, if you want to declare a variable called age and assign it the value 25, you would write age = 25.

This method allows Python to dynamically determine the type of the variable based on the assigned value, which contrasts with languages that require explicit data type declarations. This dynamic nature of Python variable declaration makes it beginner-friendly and promotes rapid development.

In contrast, defining a new function involves using the def keyword followed by the function name and its body, which is unrelated to variable declaration. Initializing a module requires importing a predefined module or script, while declaring a data type is typically a requirement in statically typed languages, not in Python. Therefore, the most accurate representation of how to declare a variable in Python is through the assignment of a value to a name.
