There may be situations in our real life programming where we need to skip a segment or set of statements and execute another segment based on the test of a condition. This is called alternative or branching.

Syntax:
if < condition >:
          statements-block 1
else:
          statements-block 2

The break statement terminates the loop containing it. Control of the program flows to the statement immediately after the body of the loop.

There are three important control Structures
(i) Sequential
(ii) Alternative or Branching
(iii) Iterative or Looping

Simple if statement: Simple if is the simplest of all decision making statements. Condition should be in the form of relational or logical expression.
Syntax:
if :
statements-block1
In the above syntax if the condition is true statements - block 1 will be executed.
Example: Program to check the age and print whether eligible for voting
x=int (input("Enter your age :"))
if x > = 18:
print ("You are eligible for voting")
Output 1:
Enter your age: 34
You are eligible for voting
Output 2:
Enter your age: 16
>>>

Python provides the following types of alternative or branching statements:
(i) Simple if statement
(ii) if..else statement
(iii) if..elif statement

A sequential statement is composed of a sequence of statements which are executed one after another. A code to print your name, address and phone number is an example of sequential statement
Example:
# Program to print your name and address - example for sequential statement
print ("Hello! This is Shyam")
print ("43, Second Lane, North Car Street, TN")
Output:
Hello! This is Shyam
43, Second Lane, North Car Street, TN

Syntax :
      while <condition>;
                statements block 1
       [else:
                statements block2]

(i) for i in range (5, 0,-1):
for j in range (1, i + 1):
print (i, end =' ')
print (end = '\n')
i+ = 1
(ii) for i in range (5, 0, -1):
for j in range (1, i + 1):
print (j end =' ')
print (i, end = '\n')
i+ = 1

The jump statement in Python, is used to unconditionally transfer the control from one part of the program to another. There are three keywords to achieve jump statements in Python: break, continue, pass. The following flowchart illustrates the use of break and continue.

(i) break statement: The break statement terminates the loop containing it. Control of the program flows to the statement immediately after the body of the loop. A while or for loop will iterate till the condition is tested false, but one can even transfer the control out of the loop (terminate) with help of break statement. When the break statement is executed, the control flow of the program comes out of the loop and starts executing the segment of code after the loop structure. If break statement is inside a nested loop (loop inside another loop), break will terminate the innermost loop.
Syntax:
break
(ii) Continue statement: Continue statement unlike the break statement is used to skip the remaining part of a loop and start with next iteration.
Syntax:
continue
(iii) Pass statement: pass statement is generally used as a placeholder. When we have a loop or function that is to be implemented in the future and not now, we cannot develop such functions or loops with empty body segment because the interpreter would raise an error. So, to avoid this we can use pass statement to construct a body that does nothing.
Syntax:
pass

Multiplication table :
num =int(input("Enter the number: "))
print("multiplication Table of", num)
for i in range(1,11):
        print (num,"x",i, "= ",num*i )
Output :
Enter the number : 6
Multiplication Table of 6
6 x 1 = 6
6 x 2 = 12
6 x 3 = 18
6 x 4 = 24
6 x 5 = 30
6 x 6 = 36
6 x 7 = 42
6 x 8 = 48
6 x 9 = 54
6 x 10 = 60.
