Why the behavior is used for a ' token in raw strings like Python, but not in C#?
Python:

Code: Select all

r'\'text' # out: '\'text'

С#(double a ' token intro a string by doubling the ' token):

Code: Select all

@'''text'  // out: ''text'

I tried the sharp'@""' notation but it's breakin

Theres no escaped ' for a string token in cobra because its unnecessary.
There is a choice of one of two delimiters for a string ('' or "")

If you want a ' (or a ") in a string you can use the other set of string delimiters

Well, there is escaped quotes in case you need to include both kinds of quotes in your string, right?

Thanks all!

Perhaps I misunderstood the question/issue.

Using the r prefix on a string treats it as a 'raw' or totally unprocessed string so there will be no escape char processing done on the contents.
any backslashes/escapes will then appear in the result

The first two are 'normal' strings ( escape processing and substitution (expression interpolation) done - substitution not used here)
the last two use raw strings so output as-is.


looks like the C# equivalent (@'????' ) uses doubled delimiters to indicate insertion of a delimiter - different approach.
cobra uses change of enclosing delimiter ('' vs "" preferably) or escaped delimiter in string

So in summary, for raw strings, you can switch between delimiters (" vs. ') and in those rare instances where you need to include both " and ' in a raw string, you can concatenate two string literals with +.

Why choose the way Python?

Because its better

Swapped delimiters are noticeably easier to read/recognise than embedded doubled punctuation.
I'd say (arguably) so are escaped characters.....

Perhaps not inconsequentially they are also slightly easier to implement correctly..
