The 's' replaces just one space match at any given time but the 's+' replaces the whole space sequence at once with the 2nd parameter.

Employing %s in scanf without an explcit discipline width opens the same buffer overflow exploit that will get did; particularly, if there are far more people in the input stream in comparison to the concentrate on buffer is sized to hold, scanf will happily create People excess people to memory outside the buffer, possibly clobbering anything significant. Regretably, in contrast to in printf, you can't supply the field with as a operate time argument:
This can be quite normal mistake-examining code for any Python script that accepts command-line arguments.
The main difference lies in the way in which it get's handled. In the event you would have a gaggle of (one example is) three spaces directly next one another s+ will take that group and turns The full it into a "", while s would proces each individual Place on its own.
The %s token allows more info me to insert (and possibly format) a string. Discover that the %s token is replaced by what ever I pass towards the string after the % image.
The PEP does not say "supplanted" As well as in no Section of the PEP will it say the % operator is deprecated (still it does say other factors are deprecated down the bottom). You would possibly desire str.structure and that's fine, but until eventually there's a PEP expressing it's deprecated there is not any sense in boasting it really is when it's not.
