In cases like this, it will make no variation, because you are changing every thing by having an vacant string (Even though It might be superior to make use of s+ from an efficiency perspective). When you were changing having a non-empty string, the two would behave in a different way. Share Increase this remedy Abide by
How can it's made the decision that a prospect has gained a point out Though not all of the votes are actually noted?
Applying %s in scanf without having an explcit industry width opens the identical buffer overflow exploit that will get did; specifically, if you will find additional people within the input stream as opposed to concentrate on buffer is sized to carry, scanf will Fortunately generate These further figures to memory exterior the buffer, likely clobbering something essential. Regrettably, contrary to in printf, You cannot provide the sector with like a run time argument:
This can be quite normal mistake-examining code for a Python script that accepts command-line arguments.
The real difference lies in how it get's managed. In case you might have a gaggle of (for example) three spaces straight following one another s+ usually takes that group and turns the whole it right into a "", even though s would proces every single Area By itself.

The PEP isn't going to say "supplanted" and in no Component of the PEP does it say the % operator is deprecated (nonetheless it does say other points are deprecated down the bottom). You may perhaps desire str.structure and that's great, but right up until there is a PEP declaring it is deprecated there isn't any perception in declaring it is actually when it isn't.
Each of the examples presented down below use arrays which has not been taught nevertheless, so I am assuming I am unable to use %s nonetheless possibly.
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.
If the worth for being output is lower than four character positions vast, the worth is right justified in the sphere by default.
If the worth is greater than 4 character positions large, the field width expands to support the right quantity of figures.
So the primary if statement translates to: should you haven't handed me an argument, I'll inform you how it is best to go me an argument Sooner or later, e.g. you'll see this on-screen:
