* Leads to fprintf to pad the output until eventually it can be n figures extensive, the place n is undoubtedly an integer worth saved during the a purpose argument just preceding that represented from the modified kind.

Individuals two replaceAll phone calls will constantly generate precisely the same end result, regardless of what x is. Having said that, it is important to note which the two standard expressions aren't a similar:

In a few code that I have to maintain, I've noticed a structure specifier %*s . Can any person inform me what this is and why it can be utilised?

5 @powersource97, %.*s usually means that you are looking at the precision worth from an argument, and precision is the most amount of characters to generally be printed, and %*s you happen to be looking through the width value from an argument, and that is the minimal selection os figures to generally be printed.

The explanation driving the code if I am utilizing %s in place of %c in my printf section on the code eighty two

Making use of scanf With all the %s conversion specifier will quit scanning at the first whitespace character; one example is, When your enter stream appears like

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.

The %s token enables me to insert (and perhaps format) a string. Observe the %s token is replaced by whatsoever I move on the string following the % symbol.

The PEP won't say "supplanted" and in no part of the PEP will it say the read more % operator is deprecated (however it does say other things are deprecated down The underside). You would possibly desire str.structure and that's fine, but until eventually there's a PEP expressing it's deprecated there is not any sense in boasting it really is when it's not.

Discover also that i'm employing a tuple here likewise (whenever you only have just one string using a tuple is optional) As an example that various strings may be inserted and formatted in one statement.

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

If the worth for being output is under four character positions huge, the value is correct justified in the field by default.

If the value is bigger than four character positions extensive, the sphere width expands to accommodate the suitable range of characters.

So the initial if statement translates to: should you haven't passed me an argument, I'll tell you how you should go me an argument Down the road, e.g. you will see this on-display screen:
