从string中生成dict

20230220

using json.loads().

import json
original_string = '{"John" : "01", "Rick" : "02", "Sam" : "03"}' 
  
# printing original string 
print("The original string is : " + str(original_string))
  
# using json.loads() method
result = json.loads(original_string)
  
# print result
print("The converted dictionary is  : " + str(result))

最好是""双引号。json默认双引号内的是dict。
