Consider this:
import collections
d = OrderedDict(a='hallo', b='world')
I wish to get a single string like this:
'a "hallo" b "world"'
Notice I wish the double quote to be part of the string.
In other words I want to wrap the value of a and b.
So the question that comes to mind is "why"? I don't mean that in the
negative sense as in you don't want to do that, but your use case may
drive the choice of possible solutions.
Reading the OP, I immediately recognised the problem - meantime others
had responded and the f'string' suggestion seemed most apropos.
Somewhat intrigued, and to answer the use-case question, I went looking
in my personal collection of RDBMS routines and "snippets" (which have
hardly been updated since Py2, excepting (IIRC) when MySQL's
Connector-Python extended into dictionary-cursors).
The Connector will automatically delimit field/colNMs passed within a
variable collection ('escaping' practice, highly recommended!) - a
SELECT clause (for example). However, such automation is not applied to
similar appearing in other clauses.
One of my helper-routines creates a comma-separated string by first
surrounding columnNMs with back-ticks and then .join()ing. It's not
rocket-surgery, but has been handy and import-ed many, many times.
YAGNI: me being me [puffs-out chest in a most unattractive fashion], one
of the function's optional arguments offers a choice of delimiter. Can't
recall ever using it 'elsewhere' though.
Thanks to the OP, and respondents making me think.
Have added to my >=v3.6 Backlog...
