What keyword is used to terminate a loop early in Python?

• A. break
• B. end
• C. exit
• D. stop

Answer: (A)

The keyword used to terminate a loop early in Python is "break." When the "break" statement is executed within a loop, it immediately stops the loop and transfers control to the statement following the loop. This is particularly useful when a certain condition is met, allowing for more efficient execution by preventing unnecessary iterations.

For instance, if you're searching through a list for a specific item and find it, you can use "break" to exit the loop right away instead of continuing to check the rest of the items. This can improve the performance of your code and is a common practice in loop control.

The other options do not serve this purpose in Python. "End" is not a keyword in Python, and using "exit" or "stop" in the context of loops does not apply. The "exit" keyword is more commonly associated with stopping the entire program, while "stop" is not recognized in Python as a keyword at all. Thus, "break" is the correct choice when referring to terminating loops early.
