The 's' replaces one particular space match at any given time although the 's+' replaces The full space sequence without delay with the second parameter.

In cases like this, 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 implement s+ from an performance point of view). Should you ended up changing which has a non-vacant string, The 2 would behave in another way. Share Enhance this reply Comply with

How can it be decided that a prospect has won a condition Despite the fact that not all the votes happen to be claimed?

Employing %s in scanf without an explcit discipline width opens the same buffer overflow exploit that gets did; particularly, if there are far more people in the input stream as opposed to concentrate on buffer is sized to carry, scanf will Fortunately write These further figures to memory exterior the buffer, likely clobbering some thing crucial. However, contrary to in printf, You can not offer the sector with like a run time argument:

That is fairly common mistake-examining code for a Python script that accepts command-line arguments.

The main difference lies in the way in which it get's handled. If you would've a bunch of (by way of example) three Areas instantly following one read more another s+ can take that group and turns The complete it right into a "", whilst s would proces each Place on its own.

The width will not be specified in the format string, but as a further integer benefit argument preceding the argument that needs to be formatted.

The %s token lets me to insert (and likely structure) a string. See the %s token is replaced by no matter what I pass for the string after 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 issues are deprecated down The underside). You could possibly favor str.structure and that is wonderful, but right until there's a PEP saying it truly is deprecated there is not any sense in saying it really is when it's not.

All the examples provided under use arrays which has not been taught still, so I am assuming I am unable to use %s nonetheless possibly.

The width isn't laid out in the structure string, but as an extra integer value argument previous the argument that needs to be formatted.

this assignation can be achieved at initialization like char term="it is a term" // the word assortment of chars received this string now and is particularly statically outlined

First off you should know that final output of equally the statements will be identical i.e. to get rid of many of the Areas from offered string.
