Question

State True or False: “A Python List must always contain all its elements of same data type.”

Hint:

Python’s dynamic typing makes lists versatile.
Always validate your list elements if your logic depends on having a specific data type.

Answer 1

Python lists are one of the most widely used data structures in Python programming.
They are ordered, mutable, and can store a collection of items in a single variable.
Unlike arrays in languages like C or Java, Python lists are not restricted to a single data type.
This means you can have an integer, a float, a string, and even another list as elements of the same list.
For example, the list [1, "Hello", 3.14, [2, 3]] is completely valid in Python.
This dynamic typing feature provides flexibility and makes Python powerful for rapid development.
However, while it is possible to mix data types, sometimes it is good practice to keep elements of the same type for logical consistency or when performing operations that expect uniform data.
Therefore, the statement that a Python list must always contain elements of the same data type is False.
