The initial regex will match just one whitespace character. The 2nd regex will reluctantly match a number of whitespace figures. For the majority of applications, both of these regexes are really similar, except in the 2nd circumstance, the regex can match extra of the string, if it helps prevent the regex match from failing. from
The first just one matches just one whitespace, While the 2nd one matches one particular or many whitespaces. They're the so-identified as regular expression quantifiers, and so they conduct matches similar to this (taken in the documentation):

The PEP will not say "supplanted" As well as 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 might want str.format and that's fine, but right until there's a PEP expressing it really is deprecated there is not any sense in saying it really is when it's not.
The mantra chocolate bars many illustrations specified beneath use arrays which hasn't been taught but, so I'm assuming I can not use %s nevertheless both.
The width is just not specified in the structure string, but as a further integer price argument preceding the argument that should be formatted.
If the value to be output is fewer than 4 character positions wide, the worth is right justified in the sector by default.
If the value is bigger than four character positions extensive, the sphere width expands to accommodate the suitable range of characters.
So the main if assertion interprets to: when you haven't passed me an argument, I'm going to tell you how you should go me an argument Down the road, e.g. you will see this on-display:
