This is particularly crucial for associates of our community who are beginners, and not familiar with the syntax. On condition that, is it possible to edit your response to include an evidence of That which you're executing and why you believe it is the greatest technique?

This is often relatively conventional error-checking code for your Python script that accepts command-line arguments.

The 1st regex will match one whitespace character. The second regex will reluctantly match a number of whitespace people. For some purposes, these two regexes are extremely equivalent, besides in the second case, the regex can match much more from the string, if it prevents the regex match from failing. from

The 1st 1 matches one whitespace, Whilst the second one particular matches one or a lot of whitespaces. They are the so-called typical expression quantifiers, plus they perform matches like this (taken through the documentation):

char character; // simply a char one letter/from the ascii map character = 'a'; // assign check here 'a' to character

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).

this assignation can be done at initialization like char phrase="this is a phrase" // the term variety of chars bought this string now and is also statically described

So the very first if statement interprets to: for those who have not handed me an argument, I will let you know how you ought to pass me an argument in the future, e.g. you will see this on-display screen:
