An error when trying to run “if” block with contents of json file

Question

Is there a different way to check if there’s specific data in json format?

with open(file, ‘r’) as f:
x = ‘example’
y = json.load(f)
if x in y:
print(‘doesnt work’)
else:
pass

Answer 1

Yes, json file should look like a python dictionary, the brackets are a must.

Example: (let's say this json file holds the name and age of students), it should look like this:

{
"john": 15,
"alex": 17,
"sofia": 16,
"mark": 17
}

Using "if x in y" will only check the names but not the age, meaning:

"'john' in y" will return True
"17" in y will return False

Answer 2

Bogdan Priymak can you post the content of your json file? Maybe the format is wrong

Answer 3

What's the error you got? The 'else' statement is useless you can remove it. Otehrwise the code should be working fine.

Answer 4

Hi!

what happens if you use:
y = json.loads(f) ----> "loads" and not "load"?

Answer 5

Thank you, now I get it. The thing is that I was able to use json.write to add just a number 3, so I thought that I should be able to access the file later

Answer 6

The error I’m getting is TypeError: argument of type ‘int’ is not iterable

Answer 7

json.loads also gives me a TypeError: the JSON object must be str, bytes or bytearray

Answer 8

The content of the file is just one number “3”. I guess that’s the problem.
