Program Plan Intro

Two-dimensional list:

  • • A list that has another list as its elements is called as two-dimensional list.
  • • Two-dimensional list is a type of nested list, where elements are arranged in row and column order.
  • • The element in the list is retrieved using two subscripts. One subscript specifies the row and other subscript specifies the column.
  • • The two-dimensional lists are helpful in processing various sets of information.

Syntax:

In Python, two-dimensional lists have the below format:

List_name = [list1, list2, …, listn]

Explanation:

Here,

  • • The variable “List_name” is a two-dimensional list.
  • • The variables “list1”, “list2”, and “listn” are elements of two-dimensional list “List_name” that indicates one-dimensional lists.

Example:

Consider the following example that shows a two-dimensional list.

student_scores = [[45, 63, 72], [81, 58, 97], [100, 23, 67]]

Explanation:

In the given above code,

  • • The variable “student_scores” is a two-dimensional list that stores the students’ scores at various exams.

Students have asked these similar questions
Write a statement that creates a two-dimensional list with three rows and four columns. Each element should be assigned the value 0.
Assume that a variable named plist refers to a list with 12 elements, each of which is an int. Assume that the variable k refers to a value between 0 and 6. Write a statement that assigns 15 to the list element whose index is k.
ID: A Name: Multiple Response Identify one or more choices that best complete the statement or answer the question. 10. The following code segment is intended to remove all duplicate elements in the list myList. The procedure does not work as intended. jt LENGTH(myList) REPEAT UNTIL(j = 1) %3D } IF(myList[j] = myList[j - 1]) %3D } REMOVE (myList, j) { j+j-1 { For which of the following contents of myList will the procedure NOT produce the intended results? a. [30, 30, 30, 10, 20, 20] b. [10, 10, 20, 20, 10, 10] c. [50, 50, 50, 50, 50, 50] d. [30, 50, 40, 10, 20, 40]
