Those people two replaceAll calls will usually deliver a similar consequence, no matter what x is. However, it is important to note which the two typical expressions are not the exact same:

And since your next parameter is vacant string "", there isn't any difference between the output of two situations.

The PEP would not say "supplanted" and in no A part of the PEP will it say the % operator is deprecated (but it does say other issues are deprecated down The underside). You could favor str.structure and that's high-quality, but right up until there is a PEP declaring it's deprecated there is not any sense in boasting it's when it's not.

The many illustrations given beneath use arrays which more info hasn't been taught nevertheless, so I'm assuming I can not use %s yet either.

The width is not laid out in the format string, but as an additional integer benefit argument previous the argument that must 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
