python in loop programming language

python in loop programming language
java programming and c, c++, Matlab, Python, HTML, CSS programming language, and new techniques news and any history.
TYPE OF LOOPS (Type of LOOP): - PYTHON consists mainly of three types of LOOP: -

01. for loop
 02. while loop
 03. Nested loops

Loop Control Statements: - Like its name, the Loop Control Statement is used to control the execution of any LOOP. For example, you suppose that you have to print numbers from 1 to 100 in the output but you want 20, 40, 60, 80 and 100 of these 100 numbers printed in the output. You can do this by using Loop Control Statements.
Type Of Loop Control Statements (Types of Loop Control Statements): - Python consists mainly of three types of Loop Control Statements.

 01. break statement
 02. continue statement
 03. pass statement

SYNTAX OF FOR LOOP

Suppose you have to print numbers from 1 to 10 in the output. Now if you print numbers from 1 to 10 in the output one by one, then this task is very difficult. But with the help of for loop, we can do this work very easily. By looking at the example below, you can understand it very easily.

Example 1:-

for c in range(1,11):

    print (c)

Output:-

1

2

3

4

5

6

7

8

9

10

Example 2:-

for n in 'PYTHON':   

   print (n)

Output:-

P

Y

T

H

O

N

Example 3:-

animals = ['tiger', 'lion', 'zebra', 'elephant', 'monkey']

for name in animals:

  print ('animal :', name)

Output:-

animal: tiger

animal: lion

animal: zebra

animal: elephant

animal: monkey

WHILE LOOP 

The syntax of while loop:-

while condition:

statement(s)

The statement in the while loop is executed until the condition of the while loop is fulfilled.

See the example below: -

Suppose we have to print numbers from 1 to 10 in the output.

Example 1:-

count = 1

while (count <= 10):

   print ('The count is:', count)

   count = count + 1

Output:-

The count is: 1

The count is: 2

The count is: 3

The count is: 4

The count is: 5

The count is: 6

The count is: 7

The count is: 8

The count is: 9

The count is: 10

BREAK STATEMENT 

For example, suppose a loop is going to print the numbers from 1 to 100 in the output, but if we want to have any number from 1 to 100, like 50 or 60, But if we stop printing, we can do this with the help of a break statement.

Because with the help of a break statement, we can create a condition from which we can control the numbers being printed in the output.

Example 1:-

for c in range(1,11):

  if c==5:

    break

  print (c)

Output:-

1

2

3

4

Example:-

shapes = ["square", "rectangle", "circle", "triangle", "oval"]

for x in shapes:

  if x == "triangle":

    break

  print('Great shape :', x)

Output:-

Great shape: square

Great shape: rectangle

Great shape: circle
