Loop Control Statements in Python 
Loop control statements alter the normal flow of a loop by stopping or skipping iterations based on specific conditions. Python provides three main loop control statements:

1. break - Terminates the loop entirely.
2. Continue - Skips the current iterations and moves to the next one.
3. pass - Acts as a placeholder, allowing the loop to run without performing any action.

1. break Statement:
The break statement is used to exit a loop immediately when a condition is met.

Example: Breaking a Loop When a Specific Value is Found
for number in range(1, 10):
   if number == 5:
       break  # Loop terminates when number is 5
   print(number)

Output:
1  
2  
3  
4  

2. Continue Statement
The continue statement skips the current iteration and moves to the next one, without exiting the loop.

Example: Skipping Even Numbers 
for number in range(1, 6):
   if number % 2 == 0:
       continue  # Skips even numbers
   print(number)

Output:
1  
3  
5  

3. pass Statement:
The pass statement does nothing and is used as a placeholder when a block of code is syntactically required but not yet implemented.

Example: Using pass in a Loopfor number in range(1, 6):
   if number == 3:
       pass  # Placeholder for future implementation
   else:
       print(number)

Output:
1  
2  
4  
5  

Key Differences Between Loop Control Statements

Statement: break 
Effect: Exits the loop immediately.

Statement: continue
Effect: Skips the current iteration and moves to the next one.

Statement: pass 
Effect: Does nothing, used as a placeholder.

These loop control statements enhance flexibility in loop execution, making code more efficient and readable.
