break, continue, and return

break and continue allow you to control the flow of your loops. They’re a concept that beginners to Python tend to misunderstand, so pay careful attention.

Using break

The break statement will completely break out of the current loop, meaning it won’t run any more of the statements contained inside of it.

>>> for name in names:
...     print(f"Hello, {name}")
...     if name == "Nina":
...         break
Hello, Rose
Hello, Max
Hello, Nina

break completely breaks out of the loop.

Using continue

continue works a little differently. Instead, it goes back to the start of the loop, skipping over any other statements contained within the loop.

>>> for name in names:
...     if name != "Nina":
...         continue
...     print(f"Hello, {name}")
Hello, Nina

continue continues to the start of the loop

What happens when we run the code from this Python file?

# Python file
names = ["Jimmy", "Rose", "Max", "Nina", "Phillip"]

for name in names:
    if len(name) != 4:

    print(f"Hello, {name}")

    if name == "Nina":

Using break and continue in nested loops.

Remember, break and continue only work for the current loop. Even though I’ve been programming Python for years, this is something that still trips me up!

>>> names = ["Rose", "Max", "Nina"]
>>> target_letter = 'x'
>>> for name in names:
...     print(f"{name} in outer loop")
...     for char in name:
...             if char == target_letter:
...                 print(f"Found {name} with letter: {target_letter}")
...                 print("breaking out of inner loop")
...                 break
Rose in outer loop
Max in outer loop
Found Max with letter: x
breaking out of inner loop
Nina in outer loop

break in the inner loop only breaks out of the inner loop! The outer loop continues to run.

Loop Control in while loops

You can also use break and continue in while loops. One common scenario is running a loop forever, until a certain condition is met.

>>> while True:
...     count += 1
...     if count == 5:
...             print("Count reached")
...             break
Count reached

Be careful that your condition will eventually be met, or else your program will get stuck in an infinite loop. For production use, it’s better to use asynchronous programming.

Loops and the return statement

Just like in functions, consider the return statement the hard kill-switch of the loop.

>>> def name_length(names):
...     for name in names:
...             print(name)
...             if name == "Nina":
...                     return "Found the special name"
>>> names = ["Max", "Nina", "Rose"]
>>> name_length(names)
'Found the special name'
