How do I write JSON data to a file? 10 answers

你可以使用json.dump()方法：

with open("text", "w") as outfile:
    json.dump({'numbers':n, 'strings':s, 'x':x, 'y':y}, outfile, indent=4)

Change:

dumps({'numbers':n, 'strings':s, 'x':x, 'y':y}, file, indent=4)

To:

file.write(dumps({'numbers':n, 'strings':s, 'x':x, 'y':y}, file, indent=4))

Also:

don't need to do file.close() . If you use with open... , then the handler is always closed properly.

result = load(file) should be result = file.read()
