The 's' replaces just one House match at any given time but the 's+' replaces the whole space sequence at the same time with the 2nd parameter.In such a case, it helps make no change, since you are replacing anything with the empty string (While It will be far better to employ s+ from an efficiency point of view).

Working with %s in scanf with out an explcit subject width opens the identical buffer overflow exploit that will get did; specifically, if you'll find additional people within the input stream when compared to the target buffer is sized to hold, scanf will happily compose All those extra characters to memory outside the buffer, probably clobbering a thing vital. Unfortunately, as opposed to in printf, you can't supply the field with as being a operate time argument:

Utilizing scanf With all the %s conversion specifier will stop scanning at the main whitespace character; one example is, Should your enter stream looks like
The width isn't laid out in the structure string, but as an additional integer price argument previous the argument that must be formatted.

The PEP won't say "supplanted" and in no Element of the PEP does it say the % operator is deprecated (yet it does say other matters are deprecated down the bottom). You may like str.format and that's fine, but right until there's a PEP expressing it's deprecated there is not any sense in professing it's when it is not.
