Question

python里面list写成json格式

gain=500，
Pot=[0.382996,0.383148,0.38269],
Accel=[0.001221,0.000763,0.001068],
Fullscale=282.448
想把他们写入一个TXT文档，打开后的格式应该是这样的{"gain":500,"Pot":[0.382996,0.383148,0.38269],"Accel":[0.001221,0.000763,0.001068],"Fullscale":282.448,}
请问各位大侠，应该怎么写啊？拜托了

Answer 1

提供一个思路（ps:本思路没有具体实践过，得靠你来完成啦！）
你可以将那几个变量构造成一个json字符串，然后直接写入文件。
all_the_text="{'gain':"+gain+",'Pot':"+Pot+",'Accel':"+Accel+",'Fullscale':"+Fullscale+",}"

python中写入文件的过程如下：

file_object = open('thefile.txt', 'w')
file_object.write(all_the_text)
file_object.close( )

def demo():
    data = {}
    data['gain'] = 500
    data['pot'] = [0.382996,0.383148,0.38269]
    data['accel'] = [0.001221,0.000763,0.001068]
    data['fullscale'] = 282.448
    import json
    f = open('data.json', 'w')
    json.dump(data, f)
    f.close()
