CONTROL STRUCTURES CHAPTER
IN PYTHON B2
Topics Covered
The student will be able to:
learn about sequential and selection control structures.
use logical operators and the random package.
work with strings and implement control statements in programs.
As you know, a computer program is a set of instructions given to the computer to perform
a specific task. These individual instructions are known as statements. All the statements are
executed sequentially, one after the other, as they appear in a program. However, in some
situations, we have to change the order of execution of the program based on certain conditions.
In such situations, we use control statements to control or change the flow of execution.
CONTROL STRUCTURE
A control structure is a programming construct that affects the flow of the execution of a program.
Various types of control structures provided by Python are shown below:
Control Structure
Sequential Statements Selection Statements Iterative Statements
SEQUENTIAL STATEMENTS Statement 1
The statements that are executed in sequential order, i.e., one after the Statement 2
other without any jumps, are called sequential statements. A sequential
structure is also known as a straight line path. Statement 3
