Individuals two replaceAll phone calls will constantly generate the identical result, in spite of what x is. Even so, it is crucial to notice the two regular expressions are certainly not the identical:

five @powersource97, %.*s implies you're examining the precision price from an argument, and precision is the maximum amount of characters to generally be printed, and %*s you will be reading through the width benefit from an argument, which can be the minimum variety os people for being printed.

The PEP isn't going to say "supplanted" and in no Element of the PEP does it say the % operator is deprecated (yet it does say other points are deprecated down the bottom).

The width just isn't specified in the structure string, but as an extra integer value argument previous the argument that needs to be formatted.
this assignation can be done at initialization like char phrase="this can be a term" // the word variety of chars got this string now which is statically outlined
For starters you need to understand that ultimate output of both the statements is going to be same i.e. to remove every one of the Areas from specified string.
