It's usually used as a placeholder where a statement is required but you're not ready to create the actual code yet. It's handy for testing other sections of code before the entire project is finished.
Particularly in older languages, this kind of statement was known as a "no-op" (no operation).

179 PointsIs it similar to continue then in terms of the functionality when he used it in the code (he didn't use it as a placeholder, he literally didn't have anything to put in there). If we kept it empty as opposed to writing pass would that create an error?

231,275 PointsA continue redirects the program flow back to the beginning of a loop, but a pass does not.

179 PointsSteven Parker I thought continue just skipped for example
names = ["John", "Jack", "Quit", "Jill"]
for name in names:
if name == "Quit":
continue
print(name)
What is printed: John, Jack, Jill
If it redirects the program to the beginning of the loop then the print wouldn't work, so what is continue? Skipping or redirecting or what?
Side Note:if I did not even use pass and left it empty, would there be an error?
Steven Parker
231,275 PointsI think we are using the words "redirects" and "skipped" to describe the same thing. The difference in functionality in the example you gave is that with the continue there, only 3 words are printed. But if you replace it with pass, then all 4 words would be printed.
