continue is an extremely important control statement. The above code indicates a typical application, where the result of a division by zero can be avoided. I use it often when I need to store the output from programs, but dont want to store the output if the program has crashed.
May 30, 2011 · Python Enhancement Proposal (PEP) 3136 suggested adding these to Python but Guido rejected it: However, I'm rejecting it on the basis that code so complicated to require this feature is very rare. In most cases there are existing work-arounds that produce clean code, for example using 'return'.
There is a fundamental difference between pass and continue in Python. pass simply does nothing, while continue jumps to the next iteration of the for loop. The statement if not 0 always evaluates to True, so both pass and continue statements will be executed. pass will do nothing and print the value, while continue will skip to the next ...
Yes, there is a difference. continue forces the loop to start at the next iteration while pass means "there is no code to execute here" and will continue through the remainder of the loop body. Run these and see the difference: for element in some_list: if not element: pass.
A line ending in a backslash cannot carry a comment. A backslash does not continue a comment. A backslash does not continue a token except for string literals (i.e., tokens other than string literals cannot be split across physical lines using a backslash). A backslash is illegal elsewhere on a line outside a string literal.
Feb 12, 2013 · This means that the word no.1 ( index = 0 ) appeard first (there's no way for something to be printed before the continue statement). The word no.2 ( index = 1 ) appeared second ( the word "hello1" managed to be printed but not the rest ) and the word no.3 appeard third what mean's that the words "hello1" and "hello2" managed to be printed before the for loop reached this said third word.
x = False. except Exception: x = True. This way what happens is that the while loop will keep on looping the try except section again and again until it works, in which x is set to false and the loop stops. Also, you can implement a break in the while loop instead of basing it on a variable, for example: while True: try:
Jul 13, 2012 · 9,666 8 62 69. This is the correct answer (if we're answering the question in the title and not the one in the description). continue is for breaking out of the current loop iteration and begin with the next iteration. If you want to just escape out of the try / except block, pass is the correct keyword if you're not doing anything inside the ...

May 11, 2012 · 42. From the python docs: When a return, break or continue statement is executed in the try suite of a try...finally statement, the finally clause is also executed ‘on the way out.’. A continue statement is illegal in the finally clause. (The reason is a problem with the current implementation — this restriction may be lifted in the future).
