A "d" prefix to do textwrap.dedent is something I wished for a long time. It's like the "f" one: we already can do it, be hell is it convenient to have a shortcut. This is especially if, like me, you take a lot of care in the error messages you give to the user. I write a LOT of them, very long, very descriptive, and I have to either import textwrap or play the concatenation game. Having a str.dedent() method would be nice, but the d prefix has the huge advantage to be able to dedent on parsing, and hence be more performant. Le 31/03/2018 à 16:50, Marius Räsener a écrit :
Hey List,
this is my very first approach to suggest a Python improvement I'd think worth discussing.
At some point, maybe with Dart 2.0 or a little earlier, Dart is now supporting multiline strings with "proper" identation (tried, but I can't find the according docs at the moment. probably due to the rather large changes related to dart 2.0 and outdated docs.)
What I have in mind is probably best described with an Example:
print(""" I am a multiline String. """)
the closing quote defines the "margin indentation" - so in this example all lines would get reduces by their leading 4 spaces, resulting in a "clean" and unintended string.
anyways, if dart or not, doesn't matter - I like the Idea and I think python3.x could benefit from it. If that's possible at all :)
I could also imagine that this "indentation cleanup" only is applied if the last quotes are on their own line? Might be too complicated though, I can't estimated or understand this...
thx for reading, Marius
