The parser will call them, passing in portions of the data, and use whatever is returned to create the overall result. Simple customizationĪside from the strict option, the keyword options available for json.load and json.loads should be callbacks. Similarly, \\\\\\\\\\\" (five pairs of backslashes, then an escaped quote) becomes \\\\\" (five backslashes and a quote equivalently, two pairs of backslashes, then an escaped quote) in the actual JSON data, which becomes \\" (two backslashes and a quote) when parsed by the JSON parser, which becomes \\\\" (two escaped backslashes and a quote) in the string representation of the parsed result (since now, the quote does not need escaping, as Python can use single quotes for the string but the backslashes still do). How can I parse the data and use the result? I think I need to use json.loads for this task, but I can't understand how to do it.įor example, suppose that I have jsonStr = 'Įach sequence of \\\" in the input becomes \" in the actual JSON data, which becomes " (embedded within a string) when parsed by the JSON parser. My Python program receives JSON data, and I need to get bits of information out of it.
