Understanding the Python Built-in Function dict()
Is the statement "The Python built-in function dict() returns a list of defined names in a namespace" True or False?
The statement "The Python built-in function dict() returns a list of defined names in a namespace" is False.
Explanation:
The Python built-in function dict() does not return a list of defined names in a namespace. Instead, it returns a new dictionary object or initializes an empty dictionary if no arguments are provided.
The dict() function in Python is used to create dictionaries, which are data structures that store key-value pairs. The keys in a dictionary must be unique and immutable, while the values can be of any data type.
To retrieve a list of defined names in a namespace, you can use the built-in function locals(), which returns a dictionary containing the current namespace's local variables. This dictionary's keys represent the variable names, and the values represent their corresponding values. For example, if you have variables x = 10 and y = "hello" defined in your code, calling locals() will return a dictionary {'x': 10, 'y': 'hello'}.
In conclusion, the dict() function in Python does not return a list of defined names in a namespace.
