I’m kind of new to python. 25 years of coding with different languages (Pascal/Pascal Object, C, PHP, javascript/typescript)

I’m using python 3.8, and requests to make API calls

I’m receiving from an API JSON datas with double backslash.

"address_1": "\",

They seems to be lost when using the .json() method of requests.Response.

So when I save those datas into an mariaDb database, and try to use JSON function, maria complains of unvalid JSON

Why ??

First I try to test json.loads()

Guess a user type hello into an input on a webpage
I want to transform this valid JSON object into a dict

{"input": "hel\lo"}

why do I get an exception with this code ?

string = '{"input": "hel\lo"}' 
dict = json.loads(string) 
print(dict) 

Invalid escape: line 1 column 15 (char 14)
  File "/home/michel/sources/test.py", line 5, in <module>
    dict = json.loads(string)
json.decoder.JSONDecodeError: Invalid escape: line 1 column 15 (char 14)

but not with this one ?

string = '{"input": "hel\lo"}'
dict = json.loads(string)
print(dict)

Insane

string = json.dumps(dict)

string value with vscode is '{"input": "hel\\lo"}'
