Overview of break continue and pass statements in python
These notes explain loop control statements, which change the normal behaviour of a loop while it is running. They cover the break statement that ends a loop early, with a pharmacy example that stops at the first critical patient, the continue statement that skips one iteration, and the pass statement that acts as a placeholder and does nothing.
Key points on break continue and pass statements in python
- Loop control statements alter the default behaviour of a loop, deciding how it proceeds, when it halts early or when an iteration should be skipped.
- The break statement ends a loop immediately, and execution jumps to the first statement after the loop without running any further iterations.
- The break statement can be placed inside both a for loop and a while loop, and is used when continuing to loop serves no further purpose.
- The continue statement skips the remaining code in the current iteration and moves on to the next iteration without ending the loop itself.
- The pass statement is a null operation used as a placeholder where Python’s syntax requires a statement but no real code needs to run yet.
Relevance to pharmacy practice
Break lets a program stop scanning patient records the moment a critical case is found, so no time is wasted checking the rest. Continue helps skip values that should be excluded from processing, and pass marks places in a program where code will be added later.
Every chapter in this subject builds on the one before it, so do not skip topics that look simple. Definitions, principles, procedures and examples are the parts that examiners return to most often, and a clear understanding here will also make later subjects easier to follow in the coming semesters.
Frequently asked questions on break continue and pass statements in python
What is the difference between break and continue in Python?
The break statement ends the whole loop for good, while continue only skips the rest of the current iteration and lets the loop carry on with the next one.
What does the pass statement do in Python?
The pass statement does nothing at all. It is a placeholder used where a loop, function or conditional block needs at least one statement but no real code is ready yet.
What is the output when break is used at i == 4 in range(1, 6)?
The program prints only 1, 2 and 3. When i becomes 4, the break statement fires and the loop ends before it can print 4 or move on to 5.

Study and exam tips
Start by reading the chapter once for the overall idea, then revise break continue and pass statements in python using headings, definitions, principles, reactions and examples. Short-answer questions in the university exam usually ask for definitions, principles, procedures, reactions and uses, so write these in your own words and practise the equations, tables and flow charts that the chapter has.
For wider reading, standard books and open resources such as the NCBI Bookshelf help you confirm terms and see more examples. Revise break continue and pass statements in python again a day later and again a week later, because spaced revision improves long-term memory.
