Which of the following is an invalid data type in python ?
To answer this question, we need to understand the different data types in Python.
In Python, there are several built-in data types, such as integers, floating-point numbers, strings, booleans, lists, tuples, sets, and dictionaries. However, "double" is not a valid data type in Python.
Let's go through each option to understand why it is correct or incorrect:
Option A) string - This option is valid because a string is a sequence of characters in Python and can be represented using single quotes ('') or double quotes ("").
Option B) complex - This option is valid because complex numbers are used to represent numbers in the form of a + bj, where a and b are real numbers, and j is the imaginary unit.
Option C) double - This option is invalid because "double" is not a valid data type in Python.
Option D) float - This option is valid because a float is a floating-point number that represents real numbers and can have a fractional part.
The correct answer is C) double. This option is incorrect because "double" is not a valid data type in Python.
