The PEP does not say "supplanted" As well as in more info no Element of the PEP will it say the % operator is deprecated (however it does say other things are deprecated down the bottom). You may want str.structure and that is good, but till there's a PEP stating it truly is deprecated there is no sense in claiming it really is when it is not.
Each of the examples offered down below use arrays which has not been taught still, so I am assuming I am unable to use %s nevertheless either.
The width will not be specified in the format string, but as yet another integer price argument previous the argument that has to be formatted.
this assignation can be done at initialization like char phrase="this is a phrase" // the term variety of chars bought this string now which is statically defined
