The 's' replaces a person space match at any given time but the 's+' replaces the whole space sequence at the same time with the second parameter.
In this instance, it will make no variation, because you are changing every little thing having an empty string (Despite the fact that It will be much better to implement s+ from an efficiency perspective). For those who were replacing using a non-empty string, the two would behave in another way. Share Increase this respond to Follow
How can it's made a decision that a candidate has gained a point out Though not all of the votes are actually documented?
Using %s in scanf devoid of an explcit area width opens the exact same buffer overflow exploit that gets did; namely, if there are actually a lot more figures during the input stream as opposed to concentrate on buffer is sized to carry, scanf will Fortunately create All those extra characters to memory outside the buffer, probably clobbering a thing important. Sadly, not like in printf, you can't supply the field with as a operate time argument:
This is certainly relatively conventional error-checking code for your Python script that accepts command-line arguments.
The difference lies in the way it get's handled. If you would've a bunch of (by way of example) 3 spaces directly next each other s+ will take that group and turns The complete it right into a "", although s would proces each space By itself.

The %s token enables me to insert (and probably format) a string. Observe the %s token is replaced by no matter what I move on the string following the % symbol.
The PEP won't say "supplanted" and 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 until finally there is a PEP stating it is actually deprecated there isn't check here any perception in professing it is when it is not.
The many illustrations given beneath use arrays which hasn't been taught nevertheless, so I am assuming I can not use %s still possibly.
How can I avoid Functioning extra time on account of children's deficiency of setting up without the need of harming them much too poorly?
this assignation can be carried out at initialization like char phrase="this is the phrase" // the term variety of chars obtained this string now and is also statically described
First off you must recognize that last output of both equally the statements will probably be similar i.e. to eliminate all of the spaces from presented string.
