I want to parse a json file and print the data in console.
I have a json file as input.json in which the content is :
{ "name":"John", "age":30, "city":"New York"}
Now I'm running a python script in the same directory where the input file is stored but getting the error. The python script looks like this :
import json
# Opening JSON file
f = open('input.json','r')
data = json.load(f)
print(data)
Error is:
File "C:\Users\madhav\Desktop\New folder (2)\instaclient\req.py", line 9, in <module>
data = json.load(f)
File "C:\Users\madhav\AppData\Local\Programs\Python\Python39\lib\json\__init__.py", line 293, in load
return loads(fp.read(),

I have a school schedule in my program, and when I use
import json
if choice == "Schedule":
with open("Schedule.json", "r") as schedule_file:
schedule_output = json.load(schedule_file)
schedule_choice = input('\nDo you want to exit or change the schedule?\n')
The problem comes up:

I tried to change the encoding, but it didn't help me.
I'm trying to load a file to a variable, but I get the error json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0) in whitelist = json.load(f), what am I doing wrong?

Not really an answer but it cannot fit into a comment. With only the error message, it is impossible to know what happens. This error can be reproduced with an empty file, or with an incorrect encoding. Example simulating an empty file:
>>> import json
>>> import io
>>> fd = io.StringIO()
>>> wl = json.load(fd)
Traceback (most recent call last):
File "<pyshell#3>", line 1, in <module>
wl = json.load(fd)

Example simulating an UTF16 encoded file read as Latin1:

The only way to discriminate the problem is to read and print the content of the file:
with open(wl, mode='r') as f:
data = f.read() # read file conten
print(data) # display it as text
print([hex(ord(i)) for i in data]) # and as an hex dump
That way you will be sure of the way Python actually reads the file.
def load_whitelist():
global whitelist
wl = "C:/Users/Administrator/Desktop/Software/whitelist.json"
if os.path.isfile(wl):
with open(wl, mode='r') as f:
whitelist = json.load(f)
f.close()
def save_whitelist():
wl = "C:/Users/Administrator/Desktop/Software/whitelist.json"
print(whitelist)
with open(wl, mode='w') as f:
json.dump(whitelist, f, sort_keys=False)
f.close()
It seems like there was an error with saving the whitelist and it deleted the JSON contents, the code itself was ok (I removed the if os.path.isfile(wl): as it was unnecessary). Thank you all for trying to help!
I have scraped some html and want to create a json doc. Here is the code I currently have:
with open(path.join(path.abspath(path.curdir),'Results\\html.txt'), 'r') as file:
for line in file.readlines():
if not line.strip():
continue
if re.findall(r'\"aggregateRating.*\"telephone\"',line):
reviews = re.findall(r'\[.*\]', line)
json_data = json.loads(str(reviews))
The error I get is: json.decoder.JSONDecodeError: Expecting value: line 1 column 2 (char 1)
Any help is appreciate. I have been stuck on this for awhile..
Your code is trying to load the string representation of a list as a valid json string; which of course will not work.
It is the same as trying to do this:
>>> json.loads(str(['hello world']))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python3.5/json/__init__.py", line 319, in loads
return _default_decoder.decode(s)
File "/usr/lib/python3.5/json/decoder.py", line 339, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "/usr/lib/python3.5/json/decoder.py", line 357, in raw_decode
raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 2 (char 1)
If you are trying to write the result as json; you need to do the opposite of loads, which is dumps:
>>> json.dumps(str(['hello world']))
'"[\'hello world\']"'
for i in os.listdir("./saves/"):
path = './saves/' + i
if path.endswith(".json"):
with open(path, "r"):
config = json.loads(path)
ctime = config["Creation Time"]
Okay, this is the small code that's causing errors. I'm getting a json decoder error Here is the callback

My saves folder is in the same working directory as my code and has one quiz.json, one notes.txt, and one __init__.py file.
I make a requests on IMDb to fetch movie information into JSON. Here's my code:
import json
import requests
url = "http://www.imdb.com/title/tt3385516/"
re = requests.get(url).json()
It get me an error which I don't know what to do with it:

I tried using
re = requests.get(url)
data = json.loads(re.text)
But it get me another error:

Response is HTML, not JSON so it can't be JSON decoded:
