The 's' replaces one Area match at a time even so the 's+' replaces The full Room sequence without delay with the next parameter.
In this case, it makes no change, since you are changing all the things using an vacant string (Despite the fact that it would be superior to make use of s+ from an effectiveness point of view). When you had been replacing by using a non-empty string, the two would behave differently. Share Strengthen this response Abide by

Utilizing %s in scanf without the need of an explcit area width opens a similar buffer overflow exploit that gets did; particularly, if there are a lot more figures during the input stream as opposed to concentrate on buffer is sized to carry, scanf will Fortunately create People more people to memory outside the house the buffer, possibly clobbering anything significant. Regretably, in contrast to in printf, you can't supply the field with as a operate time argument:
The explanation guiding the code if I am utilizing %s in place of %c in my printf section in the code eighty two
Utilizing scanf with the %s conversion specifier will prevent scanning at the primary whitespace character; as an example, if your input stream seems like
The width is not really specified in the structure string, but as yet another integer worth argument preceding the argument that needs to be formatted.
char character; // only a char one letter/with the ascii map character = 'a'; // assign 'a' to character
The PEP won't say "supplanted" and in no part of the PEP does it say the % operator is deprecated (however it does say other matters are deprecated down the bottom). You might want str.format and that's fine, but till there's a PEP stating it's deprecated there is no feeling in declaring it can be when it isn't.

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 done at initialization like char phrase="this is a phrase" // the term array of chars bought this string now and is also statically described
To begin with you'll want to recognize that ultimate output check here of both the statements might be same i.e. to remove the many spaces from given string.
