jsonstr.format()

[Skaperen]

the .format() method does not always work with JSON strings. what do you guys use instead?

More info.

Do you mean pretty printing json, formatting the str into json?

[Skaperen]

i have code that needs to put a string in where a {} is. it turns out the string where the {} is, is sometimes a string of some JSON. what .format seems to be doing is taking an earlier { and treating everything up a matching } (not sure which it used) as a string index. using .replace('{}',what_to_put_in) works.

I think you'd be better off parsing the json, and formatting whichever part needs to be formatted, instead of treating json as if it's a string.

that could be a lot of unpredictable parts when it's someone else's json.

How about the built-in json.tool? the answer to Metuburr's post

cat jsonfile.json | python -m json.tool > formatted_output.txt

If it's someone else's json, then string formatting will already be giving you unpredictable results.

what i need is a .format that can be made to use something else instead of "{}" find where to substitute stuff. but nilamo is right. playing around with strings that could have anything in them can be dangerous.
