The 's' replaces one particular Place match at any given time although the 's+' replaces The full Place sequence simultaneously with the second parameter.
On the other hand x.replaceAll("s+", ""); will be much more effective method of trimming spaces (if string might have various contiguous Areas) mainly because of probably considerably less no of replacements because of the to fact that regex s+ matches one or even more Areas without delay and replaces them with empty string.
so "indent" specifies the amount of Room to allocate for your string that follows it within the parameter record.
five @powersource97, %.*s implies you might be reading the precision benefit from an argument, and precision is the maximum range of figures to be printed, and %*s that you are looking through the width value from an argument, and that is the minimal selection os characters to generally be printed.

Using scanf with the %s conversion specifier will halt scanning at the primary whitespace character; for instance, if your input stream seems like
The initial one matches an individual whitespace, Whilst the 2nd a single matches a person or numerous whitespaces. They're the so-termed normal expression quantifiers, plus they accomplish matches like this (taken from your documentation):
char character; // merely a char one letter/within the ascii map character = 'a'; // assign 'a' to character
The PEP isn't going to say "supplanted" and in no Component of the PEP does it say the % operator is deprecated (yet it does say other points are deprecated down the bottom). You could possibly read more choose str.structure and that's high-quality, but right up until there is a PEP declaring it is deprecated there isn't any perception in proclaiming it is when it isn't.
Each of the examples supplied down below use arrays which has not been taught yet, so I'm assuming I can't use %s however either.
The width is not laid out in the format string, but as an additional integer benefit argument previous the argument that has to be formatted.
If the worth to become output is less than four character positions broad, the worth is right justified in the sphere by default.
If the worth is bigger than 4 character positions large, the sector width expands to support the right quantity of figures.
So the main if assertion interprets to: when you have not 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:
