The 's' replaces one particular House match at any given time although the 's+' replaces The complete Place sequence directly with the next parameter.
In cases like this, it tends to make no variance, because you are replacing almost everything with an empty string (While It will be far better to implement s+ from an performance point of view). In case you were being changing with a non-vacant string, The 2 would behave in different ways. Share Improve this response Observe
How can it be 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 field width opens the exact same buffer overflow exploit that receives did; namely, if you can find more characters while in the enter stream than 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 cannot offer the sector with like a run time argument:
This is certainly relatively conventional error-checking website code for your Python script that accepts command-line arguments.
The primary difference lies in just how it get's taken care of. For those who would've a bunch of (as an example) 3 Areas instantly pursuing each other s+ requires that team and turns The full it into a "", though s would proces each individual Place on its own.
The %s token enables me to insert (and perhaps format) a string. Observe the %s token is replaced by whatsoever I move on the string following the % symbol.

Discover also that i'm employing a tuple right here likewise (whenever you only have just one string employing a tuple is optional) For instance that many strings may be inserted and formatted in one statement.
How can I avoid Operating extra time on account of children's deficiency of setting up without the need of harming them much too poorly?
If the worth to get output is under four character positions huge, the worth is correct justified in the field by default.
If the value is bigger than 4 character positions extensive, the sphere width expands to accommodate the suitable number of figures.
So the 1st if assertion translates to: in case you haven't passed me an argument, I'm going to tell you how you need to pass me an argument in the future, e.g. you will see this on-display screen:
