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

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

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

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

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

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

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

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

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

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