Python - `\n` in json -


i'm using postman send post data. after posting data, body receive in request.body

{   "title": "kill bill: vol. 2","content":   "http://netflixroulette.net/api/posters/60032563.jpg\n\nabcdefrefbqwejf\n\nq efjqwefqwrf aksks" } 

i want json.loads body. however, i've new line character in json.

so, first replace \n \\n , json.loads. after replacing \n \\n, string receive :-

{\n  "title": "kill bill: vol. 2","content":\n  "http://netflixroulette.net/api/posters/60032563.jpg\n\nabcdefrefbqwejf\n\nq efjqwefqwrf aksks"\n} 

and when json.loads, results in error. because of new line character @ start of string , @ various other locations well.

any idea how can treat this?

it seems replacing actual newline character '\n' instead of text "\n".

if want remove newline strings "\n" in content, , replace them actual newlines, try replacing "\\n" '\n' (i.e. , not vice versa).

follow-on answer

here's how works, in understanding:

looking @ first , second line of request.body

{   "title": "kill bill .... 

there newline character ('\n') @ end of first line. don't see it, because being interpreted speak. 1 of many non-printable characters affect formatting when seen , interpreted various programs (e.g. text editor/viewer). trying replace "\n"'s seeing content part of .json body. these ones:

... 3.jpg\n\nab\n\nq ... 

the trouble backslash '\' used escape normal characters , access special, non-printable characters. asking replace '\n' '\\n' replacing line breaks string "\\n". can see wanted changed, "\n\n"'s still there, , instead new "\n"'s started appearing (i.e. hence quesiton).

it helps me remember in these cases, how go printing newline string not interpreted newline, shows "\n" , not like

this (the invisible 1 break). print out string, need let interpreter/text editor understand in fact want '\' character printed , not follow-on escaped character. because '\' indicates follow-on escape command, has own escape symbol, itself. is, show '\' in formatted string, put twice, "\\". thus, though looks

  ... 3.jpg\n\nab\n\nq ... 

you have needed format

  ... 3.jpg\\n\\nab\\n\\nq ... 

to way does.
