如果是字符串可以先用loads将字串转化成一个json对象，然后用dumps结构化后输出到控制台上。

一、实例：

1.字典

import json
st2 = {"data":{"actualCost":2200000,"batchId":"0","consultant":"主帐号(*7390)","contractId":"20190322238","courseInfo":"[{'courseId':'10525264607792','courseType':1,'courseName':'音乐培训','courseFeeType':1,'originCost':'200','price':47826,'purchaseClassHour':'4600','cost':20,'givingClassHour':0,'discountType':1,'discount':null,'isGroup':false,'enrollType':101}]","coursePrice":2200000,"firstPaymentId":"1434411629","firstPaymentLog":{"consultant":"主帐号(*7390)","contractId":"20190322236576568","flowType":1,"gmtCreate":"1553249381537","gmtModify":"1553249381537","id":"1109034404434411629","instId":"1051657997140361280","payStatus":4,"payTime":"1553249367748","payType":3,"price":2200000,"remark":"","saleId":"1051657997392019520","saleName":"主(*7390)","status":0,"studentId":"12706541"},"gender":1,"givingClassHour":0,"gmtCreate":"1553211","gmtModify":"1553249381411","grade":"0","instId":"1051657997140361280","instName":"小人","leftCost":0,"minusPrice":0,"otherCost":0,"payTime":"1553249367748","payType":3,"phone":"17936738367","purchaseClassHour":4600,"remark":"","saleId":"1051657997392019520","saleName":"号(*7390)","status":0,"studentId":"1109036541","studentName":"cheng","type":1},"resultCode":0,"resultMsg":"成功","totalCount":0}
b = json.dumps(st2, sort_keys=True, indent=4, separators=(',', ':'))
print(b)

2.字串
