The syntax of while loop in Python has the following syntax:

Syntax:

while: statements block 1

[else: statements block 2]

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 × 1 = 6

6 × 2 = 12

6 × 3 = 18

6 × 4 = 24

6 × 5 = 30

6 × 6 = 36

6 × 7 = 42

6 × 8 = 48

6 × 9 = 54

6 × 10 = 60

print can have end, sep as parameters, end parameter can be used when we need to give any escape sequences like ‘\t’ for tab, ‘\n’ for new line and so on. sep as parameter can be used to specify any special characters like, (comma); (semicolon) as separator between values

Escape sequences can be given using End parameter in print ( ) function.

There are 2 parameters in print function

Answer is (d) Boolean

If ………. else

Iteration or loop are used in situation when the user need to execute a block of code several of times or till the condition is satisfied. A loop statement allows to execute a statement or group of statements multiple times.

Break statement:

Break statement has even skipped the ‘else’ part of the loop and has transferred the control to the next line following the loop block.

Continue statement:

Continue statement unlike the break statement is used to skip the remaining part of a loop and start with next iteration.

n = 100

sum = 0

for counter in range (1, n + 1):

sum = sum + counter

print (“Sum of 1 until %d: %d” % (n,sum))

Output:

Sum of 1 until 100: 5050

Python provides the following types of alternative or branching statements:

Simple if statement if……else statement if….elif statement

There are 3 keywords to achieve Jump statements in python

Break is used to come out of loop.

A loop placed within another loop is called as nested loop structure. One can place a while within another while; for within another for; for within while and while within for to construct such nested loops.

Simple If is the simplest of all decision making statements.

Sep is used to specify any special characters

range ( ) generates a list of values starting from start till Stop – 1

The end value of range (30, 3, -3) is 6

Answer is (a) 12

(a) Alternative

(c) Entry check

For is the most comfortable loop

range ( ) cannot take the values from Print

range(20) has the range value from 0 to 19

Continue tatement forces the next iteration to takes place.

Pass is the null statement.

A loop placed within another loop is called as Nested loop

(d) No output

Answer is (b) :

(c) Relational or Logical expression

Sequential Statement

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

If a loop is left by Break then the else part is not executed.

Step is the optional part in range ( ) function

For is not a jump statement

jump statements are used to unconditionally transfer the control from one part of the program to another.

Interpreter.

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.

Break is not a control structure

Pass is generally used as a placeholder

There are three important control structures

1. Sequential

2. Alternative or Branching

3. Iterative or Looping

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 Else part of while is optional.

The syntax of range ( ) is as follows:

range (start, stop, [step] ) Where,

start – refers to the initial value

stop – refers to the final value

step – refers to increment value, this is optional part.

Syntax:

if:

statements – block 

else:

statements – block 2

Answer is For

A program statement that causes a jump of control from one part of the program to another is called control structure or control statement. As you have already learnt in C++, these control statements are compound statements used to alter the control flow of the process or program depending on the state of the process.

pass statement in Python programming is a null statement, pass statement when executed by the interpreter it is completely ignored. Nothing happens when pass is executed, it results in no operation. pass statement can be used in ‘if’ clause as well as within loop construct, when you do not want any statements or commands within that block to be executed

(d) Indentation

Control Structure.
