The 's' replaces 1 Room match at a time even so the 's+' replaces The entire Room sequence simultaneously with the second parameter.
In such cases, it tends to make no variance, because you are replacing almost everything with an empty string (Despite the fact that It will be much better to work with s+ from an performance standpoint). In the event you have been replacing with a non-empty string, The 2 would behave in a different way. Share Increase this respond to Follow
In some code that I have to maintain, I have noticed a structure specifier %*s . Can any person inform me what this is and why it is actually utilised?
Applying %s in scanf with no an explcit industry width opens the identical buffer overflow exploit that will get did; particularly, if there are extra people inside the enter stream when compared to the goal buffer is sized to carry, scanf will Fortunately publish These added characters to memory exterior the buffer, possibly clobbering something critical. Regrettably, as opposed to in printf, You cannot supply the field with being a operate time argument:

Employing scanf Using the %s website conversion specifier will stop scanning at the main whitespace character; by way of example, Should your enter stream looks like
The width is not specified in the structure string, but as yet another integer worth argument previous the argument that should be formatted.

The PEP doesn't say "supplanted" As well as in no Section of the PEP does it say the % operator is deprecated (still it does say other items are deprecated down The underside). You might want str.format and that's great, but until eventually there is a PEP declaring it is deprecated there isn't any perception in proclaiming it is actually when it isn't.
The many illustrations given below use arrays which hasn't been taught but, so I'm assuming I can't use %s but both.
How do I stay away from Doing work time beyond regulation resulting from teens's not enough scheduling without harming them too poorly?
If the value to generally be output is a lot less than 4 character positions huge, the value is correct justified in the field by default.
If the worth is greater than 4 character positions huge, the field width expands to accommodate the suitable number of characters.
