Break, Continue & Pass

At CIIT Training Institute, loop control statements are explained using practical examples so students can understand exactly when a loop should stop, skip an iteration or simply do nothing.

The three important statements are: break → stop the loop, continue → skip the current iteration, pass → do nothing and continue normally.

What are Loop Control Statements?

Normally, a loop executes its statements one after another. Loop control statements allow us to change this normal execution flow.

Loop Control Flow

1. break Statement

The break statement is used to immediately terminate a loop.

Once Python executes break, the loop stops completely and program execution continues with the statement after the loop.

Basic Example

for number in range(1, 10):

    if number == 5:
        break

    print(number)

Output

1
2
3
4

When number becomes 5, the break statement terminates the loop.

How break Works

for number in range(1, 6):

    print("Checking:", number)

    if number == 3:
        break

print("Loop ended")

Output

Checking: 1
Checking: 2
Checking: 3
Loop ended

The loop does not continue with 4 and 5 because break has already stopped it.

break With While Loop

number = 1

while number <= 10:

    if number == 6:
        break

    print(number)

    number += 1

Output

1
2
3
4
5

Example: Search Student 🤓🔓

Suppose we have a list of students and want to stop searching as soon as we find a particular student.

students = [
    "Rahul",
    "Priya",
    "Sam",
    "Amit",
    "Sneha"
]

for student in students:

    print("Checking:", student)

    if student == "Sam":
        print("Student Found!")
        break

Output

Checking: Rahul
Checking: Priya
Checking: Sam
Student Found!

Once Sam is found, there is no need to check the remaining students.

2. continue Statement

The continue statement skips the current iteration and moves to the next iteration of the loop.

Basic Example

for number in range(1, 6):

    if number == 3:
        continue

    print(number)

Output

1
2
4
5

Number 3 is skipped, but the loop continues with numbers 4 and 5.

How continue Works

for number in range(1, 6):

    if number == 3:
        continue

    print("Number:", number)

Output

Number: 1
Number: 2
Number: 4
Number: 5

When the value is 3, Python skips the remaining statements of that iteration.

Example: Skip Odd Numbers 📩🔓

numbers = [1, 2, 3, 4, 5, 6, 7, 8]

for number in numbers:

    if number % 2 != 0:
        continue

    print(number)

Output

2
4
6
8

Odd numbers are skipped using continue, so only even numbers are printed.

Example: Skip Inactive Students 🤓🔓

students = [
    ("Sam", True),
    ("Rahul", False),
    ("Priya", True),
    ("Amit", False)
]

for name, active in students:

    if not active:
        continue

    print("Active Student:", name)

Output

Active Student: Sam
Active Student: Priya

3. pass Statement

The pass statement is a placeholder. It does nothing when executed.

It is useful when we are planning to add code later but Python currently requires a valid statement.

Basic Example

for number in range(1, 6):

    if number == 3:
        pass

    print(number)

Output

1
2
3
4
5

Unlike break and continue, pass does not change the loop flow.

pass as a Placeholder

pass is commonly used while creating an incomplete function, class or conditional block.

def calculate_result():

    pass

The function can be completed later without causing an indentation or syntax problem.

Another Example

class Student:

    pass

break vs continue vs pass

Using break and continue Together

Both statements can be used in the same loop when different conditions require different actions.

for number in range(1, 11):

    if number == 3:
        continue

    if number == 8:
        break

    print(number)

Output

1
2
4
5
6
7

Number 3 is skipped, while the loop completely stops when number reaches 8.

break in Nested Loops

When break is used inside a nested loop, it terminates the nearest loop in which it appears.

for i in range(1, 4):

    for j in range(1, 4):

        if j == 2:
            break

        print(i, j)

Output

1 1
2 1
3 1

continue in Nested Loops

for i in range(1, 4):

    for j in range(1, 4):

        if j == 2:
            continue

        print(i, j)

Output

1 1
1 3
2 1
2 3
3 1
3 3

The value 2 is skipped in the inner loop while the outer loop continues normally.

Example: Course Search 📩🤓

courses = [
    "Python",
    ".NET",
    "Java",
    "Data Science"
]

search = "Java"

for course in courses:

    if course != search:
        continue

    print("Course Found:", course)
    break

Output

Course Found: Java

Common Mistakes

Important Interview Questions

1. What is the purpose of the break statement?
2. What is the difference between break and continue?
3. What does the pass statement do?
4. Does continue terminate a loop?
5. What happens when break is used inside a nested loop?
6. Why is pass useful when writing incomplete code?

CIIT Practice Tasks

1. Print numbers from 1 to 10, but stop the loop when the number becomes 6 using break.
2. Print numbers from 1 to 20 but skip all multiples of 3 using continue.
3. Create a student list and search for a particular student. Stop the search when the student is found.
4. Create a list of numbers and print only even numbers using continue.
5. Create a function with pass as a temporary placeholder.
6. Create a nested loop and use both break and continue to control its execution.
