Is it necessary to close the file in json.load?

Question

It's clear that a file object should be closed to delete it from memory:

file = open('data.txt', 'r')
#more code here
file.close()

Is it also necessary to close a file object served to the json.load method?

data = json.load(open('data.json','r'))

I guess no since the file object not stored in a variable, but if yes, how can it be done?

Answer 1

Don't rely on the GC to clean/close the file descriptor. Use a context manager instead.

You also don't need to provide the mode 'r' since it is the default for open .

with open('data.json') as f:
    data = json.load(f)

Answer 2

For me closing a json file works like normal file handling in python.

filename.close()
