Chapter 10 Introduction to Sequence Control Structures

10.1 What is the Sequence Control Structure?

Sequence control structure refers to the line-by-line execution by which statements are executed sequentially, in the same order in which they appear in the program, without skipping any of them. They might, for example, carry out a series of read or write operations, arithmetic operations, or assignments to variables.

The following program shows an example of Python statements that are executed sequentially.

#Prompt the user to enter value for num

num = int(input("Enter a number: "))

 

#Calculate the square of num

result = num ** 2
