The 's' replaces one particular Place match at any given time though the 's+' replaces The complete House sequence without delay with the 2nd parameter.

In this case, it can make no distinction, since you are changing everything using an vacant string (although It might be superior to utilize s+ from an effectiveness standpoint). In the event you have been changing that has a non-vacant string, The 2 would behave differently. Share Enhance this response Observe

How can it's made the decision that a prospect has gained a point out Despite the fact that not all the votes are noted?

Using %s in scanf with no an explcit field width opens precisely the same buffer overflow exploit that receives did; namely, if you will discover much more characters from the enter stream compared to the goal buffer is sized to hold, scanf will happily generate These further figures to memory exterior the buffer, potentially clobbering one thing critical. Sad to say, unlike in printf, You can not source the sphere with to be a operate time argument:

This is rather regular error-examining code for a Python script that accepts command-line arguments.

The real difference lies in the best way it get's dealt with. Should you would have a group of (for example) three spaces straight following one another s+ normally takes that group and turns The complete it into a "", here whilst s would proces every House on its own.

 

The %s token allows me to insert (and probably format) a string. Recognize the %s token is replaced by what ever I pass towards the string after the % image.

The PEP doesn't say "supplanted" As well as in no Section of the PEP does it say the % operator is deprecated (nonetheless it does say other points are deprecated down the bottom). You may perhaps want str.format and that's fine, but until eventually there's a PEP expressing it really is deprecated there is not any sense in saying it really is when it's not.

 

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 carried out at initialization like char word="this is the phrase" // the term array of chars bought this string now and is also statically described

Firstly you should know that final output of the two the statements are going to be identical i.e. to get rid of many of the spaces from offered string.
