python生成json文件

import json
control={"bw":100,"delay": "10ms","jitter": None,"loss": 0,"max_queue_size": None,
        "speedup": 0,"use_htb": True}

#data={"bw": 100,"delay": "1ms","jitter": None,"loss": 0,"max_queue_size": None,"speedup": 0,
#        "use_htb": True}
json.dump(control,open('configuration.json','w'),indent=4)
#json.dump(data,open('configuration.json','w'),indent=4)

运行就生成.json文件了，生成之后可以对文件里的内容根据自己的需要进行调整。

文件运行结果：

{
    "bw": 100,
    "delay": "10ms",
    "jitter": null,
    "loss": 0,
    "max_queue_size": null,
    "speedup": 0,
    "use_htb": true
}
