PyFormat – Practical examples of old and new style string formatting

Re:PyFormat – Practical examples of old and new style string... by x1798DE on Thursday April 16, 2015 @08:35AM (#9387473)

I think the point would be to do something like:

    a = 3
    b = 4
    c = 6
    "A is {a}, C is {c}, B is {b}".format(**locals())

Then you don't have to figure out specifying order or definitions like ".format(a=a, b=b, c=c)". I'd probably go the more explicit route in production code anyway, but for debugging / unstable development it seems useful.

I'm still not convinced. In order to write the string portion of the code, I need to know the names of the variables in play and I have to order them in them in some order in the string regardless.

So I still don't think

    "A is {a}, C is {c}, B is {b}".format(**locals())

is better than

   "A is {}, C is {}, B is {}".format(a, c, b)
