Question

Write notes on the following.

a. Write the syntax to create an array called marks with real number 56.5,92.8,80.0, 78.9 , and 95.0.
b. Write the Python program to create an array with five elements and read the elements from the keyboard and store it on the array.

Answer 1

The syntax for creating an array called marks with specific real numbers in Python uses a list, e.g., 'marks = [56.5, 92.8, 80.0, 78.9, 95.0]'. For reading from the keyboard, use a loop to append user input to the list marks.

Step-by-step explanation:

To address part a, the syntax to create an array called marks with real numbers in Python can be achieved using the list data structure, as Python does not have a native array data type like some other languages. The following line of code accomplishes this:

marks = [56.5, 92.8, 80.0, 78.9, 95.0]

For part b, the Python program to create an array with five elements and read the elements from the keyboard is as follows:

marks = []
for i in range(5):
element = float(input("Enter mark {} ".format(i+1)))
marks.append(element)

This code creates an empty list called marks, then uses a for loop that runs five times, each time prompting the user to enter a mark which is then converted to a float and appended to the marks list.
