python json dumps
Question:
i have the following string, need to turn it into a list without u”:
my_str = "[{u'name': u'squats', u'wrs': [[u'99', 8]], u'id': 2}]"
i can get rid of ” by using
import ast
str_w_quotes = ast.literal_eval(my_str)
then i do:
import json
json.dumps(str_w_quotes)
and get
[{"id": 2, "name": "squats", "wrs": [["55", 9]]}]
Is there a way to get rid of backslashes? the goal is:
[{"id": 2, "name": "squats", "wrs": [["55", 9]]}]
Answers:
>>> "[{"id": 2, "name": "squats", "wrs": [["55", 9]]}]".replace('\"',""")
'[{"id": 2, "name": "squats", "wrs": [["55", 9]]}]'
note that you could just do this on the original string
>>> "[{u'name': u'squats', u'wrs': [[u'99', 8]], u'id': 2}]".replace("u'","'")
"[{'name': 'squats', 'wrs': [['99', 8]], 'id': 2}]"
json.dumps thinks that the " is part of a the string, not part of the json formatting.
import json
json.dumps(json.load(str_w_quotes))
should give you:
[{"id": 2, "name": "squats", "wrs": [["55", 9]]}]
This works but doesn’t seem too elegant
import json
json.dumps(json.JSONDecoder().decode(str_w_quotes))
You don’t dump your string as JSON, rather you load your string as JSON.
import json
json.loads(str_w_quotes)
Your string is already in JSON format. You do not want to dump it as JSON again.
Here’s something I was working on.
Before I had the return statement as json.dumps(value) and had the issue you’re facing. But as the string is already json as yours is, adding this seems to be pointless. I returned the value and bingo ‘s gone away.
As for your other requirements I don’t know but the issue can be fixed like this.
def get(self):
CPU = psutil.cpu_percent(interval=10, percpu=False)
CORECOUNT = psutil.cpu_count(logical=False)
THREADCOUNT = psutil.cpu_count()
value = {
"CPU": CPU,
"CPU_Cores": CORECOUNT,
"CPU_Threads": THREADCOUNT,
}
return value
{"result": "{\"id\": 5, \"macaddr\": \"00:11:11:xx:11:D3\", \"ip\": \"10.46.02.313\"}'
If anybody is getting results like this with \, check if you have called json.dump twice on the same output. For me that was the case
