It says zero or maybe more prevalence of whitespace characters, accompanied by a comma after which you can accompanied by zero or maybe more prevalence of whitespace people.

In such cases, it tends to make no variance, since you are replacing almost everything with an empty string (Despite the fact that It will be far 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 differently. Share Enhance this reply Observe

so "indent" specifies the amount Room to allocate for your string that follows it within the parameter record.

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 goal buffer is sized to hold, scanf will happily publish Those people additional characters to memory outdoors the buffer, perhaps clobbering a thing important. Sadly, as opposed to in printf, you can't supply the field with as a operate time argument:

A predatory journal has a replica of our private summary, what should I do? a lot more incredibly hot questions

The real difference lies in how it get's managed. In case you might have a group of (for example) three spaces straight following one another s+ normally takes that group and turns The complete it into a "", while s would proces each individual Place on its own.

The width is just not laid out in the format string, but as a further integer benefit argument preceding the argument that needs to be formatted.

char character; // only a char 1 letter/through the ascii map character = here 'a'; // assign 'a' to character

The PEP won't say "supplanted" and in no part of the PEP will it say the % operator is deprecated (however it does say other things are deprecated down the bottom). You may prefer str.format and that is fantastic, but until there's a PEP indicating it truly is deprecated there's no feeling in saying it really is when it's 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.

The width just isn't specified in the structure string, but as an extra integer worth argument previous the argument that needs to be formatted.

this assignation can be achieved at initialization like char word="that is a word" // the phrase assortment of chars acquired this string now and is statically outlined

To begin with you have to know that remaining output of the two the statements are going to be identical i.e. to get rid of many of the Areas from offered string.
