The 's' replaces a single space match at a time however the 's+' replaces The entire Area sequence simultaneously with the second parameter.
In this instance, it will make no big difference, because you are changing every little thing by having an vacant string (Though It could be better to utilize s+ from an effectiveness standpoint). In the event you have been replacing that has a non-vacant string, The 2 would behave in another way. Share Enhance this reply Comply with
How can it be made a decision that a candidate has gained a state even though not the many votes are already reported?
Working with %s in scanf with out an explcit subject width opens the identical buffer overflow exploit that receives did; specifically, if you'll find extra characters while in the enter stream than the goal buffer is sized to hold, scanf will happily publish Those people further people to memory outside the buffer, probably clobbering a thing vital. Sadly, not like in printf, You cannot provide the field with like a run time argument:
This is reasonably standard error-examining code for just a Python script that accepts command-line arguments.
Utilizing scanf Using the %s conversion specifier will stop scanning at the main whitespace character; one example is, When your enter stream appears like
The width just isn't laid out here in the format string, but as a further integer benefit argument preceding the argument that needs to be formatted.
The %s token enables me to insert (and perhaps format) a string. Observe the %s token is replaced by whatsoever I move on the string following the % symbol.
The PEP does not say "supplanted" As well as in no Portion of the PEP will it say the % operator is deprecated (nevertheless it does say other items are deprecated down The underside). You could possibly choose str.structure and that's high-quality, but right up until there is a PEP declaring it is deprecated there is not any sense in boasting it's when it is not.
All of the examples presented down below use arrays which has not been taught yet, so I'm assuming I can't use %s however either.
How do I stay away from Performing additional time due to teenagers's lack of preparing without having harming them also badly?
If the value to generally be output is a lot less than 4 character positions large, the value is true justified in the sector by default.
If the value is larger than four character positions wide, the sector width expands to support the appropriate variety of people.
So the 1st if assertion translates to: in case you haven't passed me an argument, I'm going to tell you how you should go me an argument Down the road, e.g. you will see this on-display screen:
