What is While loop in Python?

Although known as Python is used to attach the code, so long as the trial application is not true.

Usually, we use the line if we do not already know, the number of times it's time to go.

Syntax of while Loop in Python:

while test_expression:

    Body of while

Through the circle, test the word to check first. The weight loss is only taken if the test scores are assessed correctly. After repeated, the exam reviews. This system continues until the test scores are evaluated in Final.

In Python, while the body of loop is determined by slapping.

The staff starts bleeding, and the line indicates the first end without having to go through.

Python interprets any other value. None of the 0 was interpreted as false.

Flowchart of while loop:

                                                                   

Example: Python while Loop

# Program to add natural

# numbers upto

# sum = 1+2+3+...+n

# To take input from the user,

# n = int(input("Enter n: ")) 

n = 10 

# initialize sum and counter

sum = 0

i = 1 

while i <= n:

    sum = sum + i

    i = i+1    # update counter

# print the sum

print("The sum is", sum)

Once the program is implemented, production will be:

Enter n: 10

The sum is 55

The above test feature is always true that our table is less than or equal to n (10 our programs).

We must increase the cost of change in the design process. This is very important (often forgotten). Failure to do so will result in the rounded boundary (without the circle).

The final result is shown.

while loop with else:

In the same way, we can have the option of another type.

The other is carried out when the timely delivery criteria are assessed.

Although the prosecution may be terminated. For example, for example, in the other, was ignored. Therefore, the other way to go if they do not break and the conditions are false.

Below is a simple example of this.

# Example to illustrate

# the use of else statement

# with the while loop

counter = 0

while counter < 3:

    print("Inside loop")

    counter = counter + 1

else:

    print("Inside else")

Once the program is implemented, production will be:

Inside loop

Inside loop

Inside loop

Inside else

Here, we use the variable to mark the triple stroke three times.

On the back, when that is the case. Therefore, the other part is carried out.
