Which of the following statements is true about arrays in Python?a)Arr...
Introduction:
Python is a high-level programming language that provides various data structures to store and manipulate data. One of these data structures is the array, which allows us to store multiple values of the same data type in a single variable. In Python, arrays are not as commonly used as other data structures like lists or tuples. Let's examine the given statements and determine which one is true about arrays in Python.
Explanation:
a) Arrays can have a variable length:
This statement is false. In Python, arrays have a fixed length, meaning that once an array is created, its length cannot be changed. If we need a dynamic data structure that can grow or shrink in size, we should use a list instead.
b) Array elements cannot be modified once assigned:
This statement is false. Array elements in Python can be modified. We can access individual elements of an array using their index and assign new values to them. For example, if we have an array `arr` and we want to modify its element at index 0, we can do so by using the syntax `arr[0] = new_value`.
c) Arrays in Python are implemented as linked lists:
This statement is false. Arrays in Python are not implemented as linked lists. Instead, they are typically implemented as contiguous blocks of memory, where each element occupies a fixed amount of space. This allows for efficient random access to elements based on their index.
d) Python does not have built-in support for arrays:
This statement is true. Although arrays exist in Python, they are not part of the built-in data structures provided by the language. Instead, Python provides more versatile data structures like lists, which can be used in a similar way to arrays. Lists in Python can have a variable length and allow for modification of elements. They also support additional operations like appending, slicing, and sorting.
Conclusion:
In conclusion, the statement that is true about arrays in Python is that Python does not have built-in support for arrays. While arrays can be used in Python, they are not as commonly used as other data structures like lists. It is important to choose the appropriate data structure based on the specific requirements of the program.
