* Causes fprintf to pad the output right up until it can be n figures vast, in which n is undoubtedly an integer worth saved from the a purpose argument just preceding that represented by the modified style.

In this instance, it will make no big difference, because you are changing every little thing having an empty string (Though It will be much better to work with s+ from an performance point of view). Should you ended up changing which has a non-vacant string, The 2 would behave differently. Share Boost this response Comply with

so "indent" specifies how much House to allocate for that string that follows it while in the parameter checklist.

five @powersource97, %.*s suggests you happen to be reading through the precision value from an argument, and precision is the utmost quantity of people for being printed, and %*s you're examining the width worth from an argument, which is the minimum amount amount os people for being printed.

This is reasonably standard error-examining code for any Python script that accepts command-line arguments.

The difference lies in the way in which it get's handled. If you would've a bunch of (one example is) 3 Areas instantly next each other s+ takes that team and turns The entire it right into a "", when s would proces just about every Room on its own.

 

The %s token allows me to insert (and probably format) a string. Recognize the %s token is replaced by no matter what I pass towards the string after the % image.

The PEP does not say "supplanted" As well as in no Portion of the PEP does it say the % operator is deprecated (still it does say other factors are deprecated down the bottom). You may perhaps desire str.format and that's great, but until eventually there's a PEP expressing it really is deprecated there is not any sense in claiming it click here truly is when it's not.

All the examples presented down below use arrays which has not been taught yet, so I'm assuming I can't use %s nevertheless both.

The width is just not specified in the structure string, but as a further integer worth argument preceding the argument that should be formatted.

If the value to become output is fewer than 4 character positions broad, the worth is right justified in the sector by default.

If the value is larger than four character positions wide, the sector width expands to support the appropriate amount of people.

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