Question

A DataFrame student consist 10 records of students that include

rollno,name,gender and age

i. How many elements in student()ii What is the shape of student​

Answer 1

(i) 40

(ii) (10, 4)

(i) A DataFrame is a two-dimensional data structure, similar to a spreadsheet, that consists of rows and columns. The total number of elements in a DataFrame is equal to the number of rows multiplied by the number of columns.

Since there are records of 10 students the data frame has 10 rows and 4 columns of attributes ( roll no,name,gender and age ).

If the DataFrame has 10 rows and 4 columns, it will have a total of:

10 x 4 = 40

40 elements.

(ii)The shape of a DataFrame is a tuple that indicates the number of rows and columns it has, in that order.

the DataFrame has 10 rows and 4 columns (rollno, name, gender, and age), its shape would be (10, 4).
