for i,x in enumerate(arr): if i % 2 == 0: # skip even members continue do_something_odd(x)
continue is used within looping structures to skip the rest of the current loop iteration and continue execution at the condition evaluation and then the beginning of the next iteration.
continue accepts an optional numeric argument which tells it how many levels of enclosing loops it should skip to the end of.
Omitting the semicolon after continue can lead to confusion. Here's an example of what you shouldn't do.
One can expect the result to be :
0 1 3 4
but this script will output :
because the return value of the print() call is int(1), and it will look like the optional numeric argument mentioned above.
