15. Explain break, continue, and pass Statements in Python -

Python provides loop control statements — break, continue, and pass — to control the flow of loops (for or while).
These statements help in skipping, terminating, or doing nothing during iteration.

Statement	Description	Use Case
`break`	Terminates the current loop and transfers control to the next statement after the loop.	When you want to exit the loop early based on a condition.
`continue`	Skips the current iteration and moves to the next iteration of the loop.	When you want to skip specific iterations but continue looping.
`pass`	Does nothing; it’s a placeholder used when a statement is syntactically required but you don’t want to execute any code.	Used as a placeholder for future code or empty blocks.

🧩 Example 1: Using break

for i in range(1, 6):
    if i == 3:
        break  # Stop the loop when i equals 3
    print(i)

for i in range(1, 6):
    if i == 3:
        break  # Stop the loop when i equals 3
    print(i)

Output:

1
2

1
2

(Loop stops as soon as i becomes 3.)

🧩 Example 2: Using continue

for i in range(1, 6):
    if i == 3:
        continue  # Skip the current iteration when i equals 3
    print(i)

for i in range(1, 6):
    if i == 3:
        continue  # Skip the current iteration when i equals 3
    print(i)

Output:

(i = 3 is skipped, loop continues for remaining values.)

🧩 Example 3: Using pass

for i in range(1, 6):
    if i == 3:
        pass  # Do nothing, placeholder for future logic
    print(i)

for i in range(1, 6):
    if i == 3:
        pass  # Do nothing, placeholder for future logic
    print(i)

Output:

(pass simply does nothing and allows the program to continue.)

🧩 Example 4: Using in while Loop

i = 1
while i <= 5:
    if i == 3:
        i += 1
        continue
    if i == 5:
        break
    print(i)
    i += 1

i = 1
while i <= 5:
    if i == 3:
        i += 1
        continue
    if i == 5:
        break
    print(i)
    i += 1

Output:

1
2
4

1
2
4

🧩 Example 5: Using pass as a Placeholder

def future_function():
    pass  # Function defined but implementation will be added later

class MyClass:
    pass  # Class placeholder

def future_function():
    pass  # Function defined but implementation will be added later

class MyClass:
    pass  # Class placeholder

Output:

# No output, but valid syntax — used for structure definition

# No output, but valid syntax — used for structure definition

🔹 In Summary

break → Immediately terminates the loop.
continue → Skips the current iteration and continues with the next one.
pass → Does nothing, used as a placeholder for empty code blocks.

These control statements help improve loop control, code readability, and logical flow management in Python programs.
