Loop Control Statements

Loop control statements in Python alter the flow of execution within loops (primarily for and while loops). They allow you to skip iterations, terminate the loop prematurely, or jump to a specific point within the loop.

The key loop control statements are:

• break: Terminates the loop entirely and transfers control to the statement immediately following the loop.

for i in range(1, 11):
    if i == 5:
        break  # Exit loop when i is 5
    print(i) 

• continue: Skips the rest of the current iteration and proceeds to the next iteration of the loop.

for i in range(1, 11):
    if i % 2 == 0:
        continue  # Skip even numbers
    print(i)

• pass: Acts as a placeholder. It does nothing. Often used where syntactically a statement is required, but you don’t want any action to be performed. Useful in defining empty functions or loops which you intend to implement later.

for i in range(1, 11):
    if i % 2 == 0:
        pass  # Do nothing for even numbers
    else:
        print(i)

• else clause in loops: The else block is executed only if the loop completes normally (without encountering a break statement).

for i in range(1, 11):
    if i == 15: #this condition will never be met
        break
    print(i)
else:
    print("Loop completed normally") #This will always print

for i in range(1, 11):
    if i == 5:
        break
    print(i)
else:
    print("Loop completed normally") #This will not print
