Why doesn't this JSON load in python?

For a couple of days i've been trying to learn how to use JSON in python, but even if i copy everything from tutorials it still won't load.
import json
data = '''
{
"people":[
{
"name": "veljko",
"age":"20",
"email": veljkov02#gail.com,
"educated": "true"
} ,
{
"name":"aleksandar",
"age":"24",
"email":"marko99#gmail.com",
"educated":"false"
}
]
}
'''
men = json.loads(data)
print(men)
(Ignore the random words used in code, it's just how i learn)
It just keeps giving the same error messages, i've tried with the most simple JSON but it's still the same.
Traceback (most recent call last):
File "C:\Users\*********\Desktop\code3\json.py", line 21, in <module>
men = json.loads(data)
File "C:\Users\************\AppData\Local\Programs\Python\Python310\lib\json\__init__.py", line 346, in loads
return _default_decoder.decode(s)
File "C:\Users\*************\AppData\Local\Programs\Python\Python310\lib\json\decoder.py", line 337, in decode.
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "C:\Users\************\AppData\Local\Programs\Python\Python310\lib\json\decoder.py", line 355, in raw_decode
raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 7 column 14 (char 75)
Process finished with exit code 1
Please help, i'm a begginer and am not sure how to solve this problem.

You are missing quotes around veljkov02#gail.com. You need to change it to "veljkov02#gail.com", so that it is interpreted as a string. The exception tells you which line and character the error is at, so double check that line when you get errors like these.

Problem of Python running code error on Pycharm

I'm using Pycharm professional 2019.03 to execute Python code Streaming Twitter Filter. The running code finish unsuccessfully with message error :
Traceback (most recent call last):
File "C:/Users/HP/PycharmProjects/Twitter_Stream/twitter_filter.py", line 12, in <module>
with open(file_path) as f:
FileNotFoundError: [Errno 2] No such file or directory: '/config/api.json'
When I ran the script print(os.getcwd()) the result is C:\Users\HP\PycharmProjects\Twitter_Stream
The Run/Debug configurations Windows show that the working directory is
C:\Users\HP\PycharmProjects\Twitter_Stream and all seem ok but I dont know why this message error. The api.json file is in the same directory than twitter_filter.py
I tried to replace the code :
file_path = '/config/api.json' by file_path = '/Users/HP/PycharmProjects/Twitter_Stream/config/api.json' or
file_path = 'C:/Users/HP/PycharmProjects/Twitter_Stream/config/api.json',
I have this message error :
Traceback (most recent call last):
File "C:/Users/HP/PycharmProjects/Twitter_Stream/twitter_filter.py", line 13, in <module>
twitter_api = json.loads(f.read())

obj, end = self.scan_once(s, idx)
json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes: line 3 column 5 (char 7)
Please someone can help me to solve thise problem? Let me know if you need more information
Thank you !

(I would comment but I do not have enough rep points.)
When you see the JSONDecodeError, it means the JSON file is successfully being read by the module.
However, it appears the module deems the file invalid.
From past experiences, I would check if the JSON file is valid with this link: https://jsonformatter.curiousconcept.com/
I think what could be wrong is that your JSON file is using single quotes instead of double quotes, so not properly formatted.

Python JSON double quote errors

I am having JSON syntax issues when I am using the following code code: https://github.com/clarkbk/streeteasy-analysis
Using this JSON in buildings.json
{
"buildings": [
{
"name": "Henry Hall",
"addr": "https://streeteasy.com/nyc/property_activity/past_transactions_component/799324?all_activity=true&show_rentals=true&style=xls",
"id": 799324,
}
]
}
I am getting the following error:
2019-05-25 16:04:26,641 - INFO - Starting...
Traceback (most recent call last):

I have researched for a few hours now on how to fix this but can't come up with a fix. I am not that familiar with JSON in general but I don't know where I am not double qouting properly. Appreciate any help with this.

The line number gives a good hint
you want:
"id": 799324
}
(note no comma after the last element)
json isn't python ast.literal_eval, if there's a comma on last element it fails, because it expects another property as the message states (Expecting property name enclosed in double quotes explains that, although the message could be better, as this error is very common)
If you have data like this, you can use ast.literal_eval on it instead, it will work without modifications (unless there are false or null json booleans/null-pointers)

Not able to import json from commandline for Python

I am currently tring to work with import a json input that is accepted by Python through a commandline argument and I am trying to save the different values to JSON to a list. I am having issues with my code given below and have attached both the code and the error I get below. Any help much appreciated.
import sys
import json
def lookup1 ():
jsonData = json.loads(sys.argv[1])
print jsonData
jsonList = [jsonData['proxy'],jsonData['OS']]
print jsonList
lookup1()
The error is given below:
$ python dynamicMapper.py '{'proxy':1,'OS':2}'
Traceback (most recent call last):
File "dynamicMapper.py", line 9, in <module>
lookup1()
File "dynamicMapper.py", line 4, in lookup1
jsonData = json.loads(sys.argv[1])
File "/usr/lib/python2.7/json/__init__.py", line 338, in loads
return _default_decoder.decode(s)
File "/usr/lib/python2.7/json/decoder.py", line 366, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "/usr/lib/python2.7/json/decoder.py", line 382, in raw_decode
obj, end = self.scan_once(s, idx)
ValueError: Expecting property name: line 1 column 2 (char 1)
The commadline argunet that I give is python dynamicMapper.py '{'proxy':1,'OS':2}'
I am not able to find out what is causing this error and if my approach is right.

The script is working fine, you just need to call it the right way:
python dynamicMapper.py '{"proxy":1,"OS":2}'
{u'OS': 2, u'proxy': 1}
[1, 2]
In JSON the strings are quoted with double quotes instead of single quotes. You also need to quote the string passed to script so that shell understands it being a single argument.

Trouble parsing JSON object in Python

I am trying to parse some text files containing JSON objects in Python using the json.load() method. It's working for one set of them, but for this one it will not:
{
"mapinfolist":{
"mapinfo":[
{"sku":"00028-0059","price":"38.35","percent":"50","basepercent":"50","exact":0,"match":0,"roundup":0}
,{"sku":"77826-7230","price":"4.18","percent":"60","basepercent":"60","exact":1,"match":0,"roundup":0}
,{"sku":"77827-1310","price":"2.36","percent":"60","basepercent":"60","exact":1,"match":0,"roundup":0}
,{"sku":"77827-2020","price":"2.36","percent":"60","basepercent":"60","exact":1,"match":0,"roundup":0}
,{"sku":"77827-3360","price":"2.36","percent":"60","basepercent":"60","exact":1,"match":0,"roundup":0}
,{"sku":"77827-4060","price":"2.36","percent":"60","basepercent":"60","exact":1,"match":0,"roundup":0}
,{"sku":"77827-4510","price":"2.36","percent":"60","basepercent":"60","exact":1,"match":0,"roundup":0}
,{"sku":"77827-7230","price":"2.36","percent":"60","basepercent":"60","exact":1,"match":0,"roundup":0}
],
"count":2
}
}
It is in a file called 'map.txt' - I open it using open('map.txt') and then call json.load(). When I run my test program (test.py), the following error trace is generated:
Traceback (most recent call last):
File "test.py", line 28, in <module>
main()
File "test.py", line 23, in main
map_list = json.load(f1)
File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/json/__init__.py", line 268, in load
parse_constant=parse_constant, object_pairs_hook=object_pairs_hook, **kw)
File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/json/__init__.py", line 318, in loads
return _default_decoder.decode(s)
File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/json/decoder.py", line 343, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/json/decoder.py", line 361, in raw_decode
raise ValueError(errmsg("Expecting value", s, err.value)) from None
ValueError: Expecting value: line 1 column 1 (char 0)
The JSON object is valid - when I put it into https://www.jsoneditoronline.org/ it is parsed and displayed correctly, so I am having trouble identifying what could be stopping it from working when I try to do it in Python. Any advice would be much appreciated. Thanks!
EDIT: Here's my code.
import json
def main():
with open('map.txt') as f1:
map_list = json.load(f1)
Trying map_list = json.loads(f1.read()) also does not work and gives me an almost identical error trace.
EDIT - RESOLVED:
I just copied and pasted FROM map.txt into a new TextEdit file map2.txt and used the new file instead, and it works now. I copied directly from the old file and made no changes - the only difference is that it is a different file. I can't make heads or tails of why that would be - any ideas? I would like to understand what may have happened so I can avoid the problem in the future.

Does the following solution work for you?
import json
f = open("map.txt")
map = json.loads(f.read())
Python Docs

maybe try to read all the file to string and then use json.loads
def yourfunc():
file = open('map.txt')
json_string = file.read()
map = json.loads(json_string)
