Python Tutorials - While loop

In this blog, we are going to see the loop in the python programming language. There are two primitive loops in python.

while

for

While loop:

While loop will repeat the statement until the condition is true. While loop requires a relevant indexing variable. We will declare 'i' here. Which we will set the values as 1.

Example:               

  i=1 

while i<6: 

print(i) 

i+=1

Output:

               1

               2

               3

               4

               5

Explanation:         

           Inline 1, we will assign the value 1 for i. Inline 2 we will use while keyword which defines that it executes the statement until it reaches the value before 6. Inline 3 will print the i.Inline 4, it will increase the value as 1,2,3 and so on until it reaches the condition.

Break Statement:

  The break statement is used to break the loop even the while condition is true. 

Example:

i=1               

 while i<6: 

                      print(i)

                        if i==3:

                            break

                        i+=1 Output:

                1

                2

                3 Continue statement:     

                 Continue statement is used to break the current iteration and it will continue with the next one. Example: 

               i = 0

                while i < 6:

                       i += 1 

                    if i == 3:   

                    continue

                      print(i)  Output: 

             1

               2

               4

               5

else statement: 

                 Else statement in loop condition is used to execute the code block once when the condition is no longer true. Example:

                 i = 1

                 while i < 6:

                      print(i) 

                    i += 1

                  else:

                      print("i is no longer less than 6") Output:

              1

              2 

            3

              4

5

i is no longer less than 6
