Python while loop continue + Examples

In this Python tutorial, we will discuss the Python While loop continue. Here we will also cover the below examples:

• Python while loop continue break
• Python while loop exception continue
• Python nested while loop continue
• Python while true loop continue
• While loop continue python example
• Python continue while loop after exception
• Python try except continue while loop
• Python while loop break and continue

Python while loop continue

• Let us see how to use the continue statement in the While loop in Python.
• Continue is used to skip the part of the loop. This statement executes the loop to continue the next iteration.
• In python, the continue statement always returns and moves the control back to the top of the while loop.

Example:

Let’s take an example and check how to use the continue statement in the while loop

new_var = 8
while new_var >0:
    new_var=new_var-1
    if new_var==2:
        continue
    print(new_var)
print("loop end")

In the above code, we will first initialize a variable with 8 and check whether 8 is greater than 0. Here you can see it is true so I will go for a decrement statement that 8-1 and it will display the variable value as 7. it will check whether a variable is equal to 2. In the above code, you will check that it is not equal to the variable and it will print the value 7.

Here is the output of the following above code

Another example is to check how to use the continue statement in the while loop in Python.

Example:

z = 8
while z > 1:
    z -= 2
    if z == 3:
        continue
    print(z)
print('Loop terminate:')

Python while loop continue break

• In python, the break and continue statements are jump statements. The break statement is used to terminate the loop while in the case of the continue statement it is used to continue the next iterative in the loop.
• In the break statement, the control is transfer outside the loop while in the case of continue statement the control remains in the same loop.

Example:

while True:
    result = input('enter a for the loop: ')
    if result == 'a':
        break
print('exit loop')

a = 0
while a <= 8 :
    a += 1
    if a % 4 == 1 :
        continue
    print(a)

In the above code, we will create a while loop and print the result 2 to 8, But when we get an odd number in the while loop, we will continue the next loop. While in the case of the break statement example we will give the condition that if the user takes the input as ‘a’ it will exit the loop.

Python while loop exception continue

• Let us see how to use the exception method in the while loop continue statement in Python.
• An exception is an event that occurs normally during the execution of a programm.
• If a statement is systematically correct then it executes the programm. Exception means error detection during execution.
• In this example, we can easily use the try-except block to execute the code. Try is basically the keyword that is used to keep the code segments While in the case of except it is the segment that is actually used to handle the exception.

Example:

while True:
    try:
        b = int(input("enter a value: "))
        break
    except  ValueError:
        print("Value is not valid")

Python nested while loop continue

• Let us see how to use nested while loop in Python.
• In this example, we will use the continue statement in the structure of the within while loop based on some important conditions.

Example:

Let’s take an example and check how to use nested while loop in Python

c = 2
while c < 4 :
    d = 1
    while d < 10 :
        if d % 2 == 1 :
            d += 1
            continue
        print(c*d, end=" ")
        d += 1
    print()
    c += 1

Here is the execution of the following given code

This is how to use nested while loop in python.

Python while true loop continue

In Python, the while loop starts if the given condition evaluates to true. If the break keyword is found in any missing syntax during the execution of the loop, the loop ends immediately.

Example:

while True:
    output = int(input("Enter the value: "))
    if output % 2 != 0:
        print("Number is odd")
        break
    
    print("Number is even")

In the above code, we will create a while loop and print the result whether it is an even number or not, when we get an odd number in the while loop, we will continue the next loop. In this example we take a user input when the user enters the value it will check the condition if it is divide by 2 then the number is even otherwise odd.

Here is the implementation of the following given code

While loop continue Python example

• Here we can see how to use the continue statement while loop.
• In this example first, we will take a variable and assign them a value. Now when n is 4 the continue statement will execute that iteration. Thus the 4 value is not printed and execution returns to the beginning of the loop.

Example:

Let’s take an example and check how to use the continue statement in the while loop

l = 6
while l > 0:
    l -= 1
    if l == 4:
        continue
    print(l)
print('Loop terminate')

Output

Another example to check how to apply the continue statement in the while loop

Example:

t = 8                  
while 8 > 0:              
   print ('New value :', t)
   t = t-1
   if t == 4:
      break

print ("Loop end")

Here is the output of the program

Python try except continue while loop

• Here we can check how to apply the try-except method in the continue while loop.
• In this example, I want to convert the input value inside a while loop to an int. In this case, if the value is not an integer it will display an error and continue with the loop.

Example:

m=0
new_var=0
l = input("Enter the value.")
while l!=str("done"):
     try:
          l=float(l)
     except:
          print ("Not a valid number")
          continue
     m=m+1
     new_var = l + new_var      
     l= input("Enter the value.")
new_avg=new_var/m
print (new_var, "\g", m, "\g", new_avg)

Here is the implementation of the following given code

Python while loop break and continue

• In Python, there are two statements that can easily handle the situation and control the flow of a loop.
• The break statement executes the current loop. This statement will execute the innermost loop and can be used in both cases while and for loop.
• The continue statement always returns the control to the top of the while loop. This statement does not execute but continues on the next iteration item.

Example:

Let’s take an example and check how to use the break and continue statement in while loop

k = 8                    
while k > 0:              
   print ('New value :', k)
   k = k -1
   if k == 4:
      break

print ("loop terminate")

b = 0
while b <= 8 :
    b += 1
    if b % 4 == 1 :
        continue
    print(b)
  

Output:

This is how to use the break and continue statement in while loop
