In certain code that I have to take care of, I have found a format specifier %*s . Can anybody notify me what That is and why it's used?
five @powersource97, %.*s signifies you will be looking at the precision worth from an argument, and precision is the most quantity of people for being printed, and %*s you're examining the width worth from an argument, which happens to be the bare minimum number os figures to generally be printed.

You would possibly choose str.structure and that's high-quality, but until finally there is a PEP stating it click here is actually deprecated there is no perception in declaring it can be when it isn't.
The many illustrations given beneath use arrays which hasn't been taught nevertheless, so I am assuming I can not use %s still possibly.
The width is not laid out in the format string, but as an extra integer value argument previous the argument that must be formatted.
If the worth for being output is under 4 character positions large, the value is true justified in the sector by default.
If the value is larger than four character positions wide, the sector width expands to support the right range of characters.
The subsequent if statement checks to determine if the 'databases-name' you handed on the script truly exists on the filesystem. Otherwise, you'll get a concept like this:
