python json

json.load:把文件打开，并把字符串变换为数据类型

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

dump: 将数据写入json文件中

 

#ensure_ascii= False  ->保证写入的json文件不是Unicode编码(显示中文)

with open("../config/record.json","w") as f:
    json.dump(new_dict,f,ensure_ascii= False,indent = 2)

loads: 将 字符串 转换为 字典

dict = json.loads(json_str)
print(dict)
print(type(dict))

dumps：将python中的 字典 转换为 字符串

将json写入到文件中：

f2.write(json.dumps(train_set, ensure_ascii=False, indent=2))

json转CSV输出

import json,csv
csv_out = open('out.csv','w')
write = csv.writer(csv_out)
for k,v in res.items():
    write.writerow([k,v])
csv_out.close()
