Python|字典和字节之间的相互转换

数据之间的相互转换非常流行，这篇特别的文章讨论了如何获得字典到字节的相互转换，反之亦然。让我们看看可以帮助我们完成这个特定任务的方法。

方法：使用encode() + dumps() + decode() + loads()
编码和转储函数一起执行将字典转换为字符串然后转换为相应字节值的任务。这可以使用解码和加载函数相互转换，该函数从字节返回字符串并将其再次转换为字典。

# Python3 code to demonstrate working of
# Interconversion between Dictionary and Bytes
# Using encode() + dumps() + decode() + loads()
import json
  
# initializing dictionary
test_dict = {'Gfg' : 1, 'is' : 2, 'best' : 3}
  
# printing original dictionary
print("The original dictionary is : " + str(test_dict))
  
# using encode() + dumps() to convert to bytes
res_bytes = json.dumps(test_dict).encode('utf-8')
  
# printing type and binary dict 
print("The type after conversion to bytes is : " + str(type(res_bytes)))
print("The value after conversion to bytes is : " + str(res_bytes))
  
# using decode() + loads() to convert to dictionary
res_dict = json.loads(res_bytes.decode('utf-8'))
  
# printing type and dict 
print("The type after conversion to dict is : " + str(type(res_dict)))
print("The value after conversion to dict is : " + str(res_dict))

输出 ：

The original dictionary is : {'Gfg': 1, 'best': 3, 'is': 2}
The type after conversion to bytes is : 
The value after conversion to bytes is : b'{"Gfg": 1, "best": 3, "is": 2}'
The type after conversion to dict is : 
The value after conversion to dict is : {'Gfg': 1, 'best': 3, 'is': 2}
