It claims zero or more event of whitespace figures, followed by a comma after which followed by zero or more occurrence of whitespace characters.
In this case, it can make no distinction, since you are replacing all the things using an vacant string (Whilst it would be greater to use s+ from an efficiency perspective). In case you were being changing with a non-vacant string, the two would behave differently. Share Increase this answer Abide by
so "indent" specifies the amount Room to allocate for your string that follows it within the parameter record.
five @powersource97, %.*s suggests you happen to be reading through the precision benefit from an argument, and precision is the utmost quantity of people for being printed, and %*s you are looking at the width worth from an argument, which is the least quantity os characters to get printed.
The clarification at the rear of the code if i'm employing %s rather than %c in my printf part from the code 82
Applying scanf Along with the %s conversion specifier will end scanning at the initial whitespace character; for example, In the event your input stream seems like
The width will not be specified in the format string, but as yet another integer value argument preceding the argument that should be formatted.
The %s token makes it possible for me to insert (and most likely structure) a string. Detect the %s token is changed by regardless of what I go to your string once the % symbol.
The PEP will not say "supplanted" As well as in no Component 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 is a PEP stating it can be deprecated there is no feeling in claiming it can be when it's not.
The many illustrations specified below use arrays which hasn't been taught but, so I'm assuming I can't use %s but both.
The width is not really laid out in the format string, but as an additional integer benefit argument previous the argument that must be formatted.
If the worth to be output is fewer than 4 character positions wide, the value is right justified in the sector by default.
If the value is bigger than four character positions vast, the sphere width expands to support the appropriate range of characters.
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 go me an argument Down the road, e.g. you will see more info this on-display screen:
