1.json.dumps()用于将dict类型的数据转成str
import json

dict = {‘a‘: ‘wo‘, ‘b‘: ‘zai‘, ‘c‘: ‘zhe‘, ‘d‘: ‘li‘}
string = json.dumps(dict)
print(dict)
print(string)
print(type(dict))
print(type(string))

with open(r‘C:\Users\zy\Documents\GitHub\python3\searchTest\json.json‘,‘w‘)as f:
      f.write(string)

2.json.dump()用于将dict类型的数据转成str，并写入到json文件中

dict = {‘a‘: ‘wo‘, ‘b‘: ‘zai‘, ‘c‘: ‘zhe‘, ‘d‘: ‘li‘}
json.dump(dict,open(r‘C:\Users\zy\Documents\GitHub\python3\searchTest\json.json‘,‘w‘))

3.json.loads():用于将str类型的数据转成dict

dict = {‘a‘: ‘wo‘, ‘b‘: ‘zai‘, ‘c‘: ‘zhe‘, ‘d‘: ‘li‘}
dumps = json.dumps(dict)
loads = json.loads(dumps)

print(dict)
print(dumps)
print(loads)

print(type(dict))
print(type(dumps))
print(type(loads))

4.json.load()用于从json文件中读取数据

filename = (r‘C:\Users\zy\Documents\GitHub\python3\searchTest\json.json‘)
jsObj = json.load(open(filename))
print(jsObj)
print(type(jsObj))
