JSON.stringify (Javascript) and json.dumps (Python) not equivalent on a list?
Question:
In javascript:
var myarray = [2, 3];
var json_myarray = JSON.stringify(myarray) // '[2,3]'
But in Python:
import json
mylist = [2, 3]
json_mylist = json.dumps(mylist) # '[2, 3]' <-- Note the space
So the 2 functions aren’t equivalent. It’s a bit unexpected for me and a bit problematic when trying to compare some data for example.
Some explanation about it?
Answers:
The difference is that json.dumps applies some minor pretty-printing by default but JSON.stringify does not.
To remove all whitespace, like JSON.stringify, you need to specify the separators.
json_mylist = json.dumps(mylist, separators=(',', ':'))
