如果需要保存Python运行中的某个dict对象，或者从硬盘里的JSON读进内存，可以用下面命令
import json
# Serialize data into file:
json.dump( data, open( "file_name.json", 'w' ) )
# Read data from file:
data = json.load( open( "file_name.json" ) )
import json
# Serialize data into file:
json.dump( data, open( "file_name.json", 'w' ) )
# Read data from file:
data = json.load( open( "file_name.json" ) )
import json # Serialize data into file: json.dump( data, open( "file_name.json", 'w' ) ) # Read data from file: data = json.load( open( "file_name.json" ) )
