您好，我想知道如何從矩陣中的 json 資料中獲取資料？為了更好地解釋：
{
"00": "Echo reply",
"03":{ "00" : "Destination Unreachable - Net Unreachable",
"01" : "Destination Unreachable - Host Unreachable",
"02" : "Destination Unreachable - Protocol Unreachable",
"03" : "Destination Unreachable - Port Unreachable",
"04" : "Destination Unreachable - Fragmentation Needed & DF Set",
"05" : "Destination Unreachable - Source Route Failed",
"06" : "Destination Unreachable - Destination Network Unknown",
"07" : "Destination Unreachable - Destination Host unknown",
"08" : "Destination Unreachable - Source Host Isolated",
"09" : "Destination Unreachable - Network Administratively Prohibited",
"0a" : "Destination Unreachable - Host Administratively Prohibited",
"0b" : "Destination Unreachable - Network unreachable for TOS",
"0c" : "Destination Unreachable - Host unreachable for TOS",
"0d" : "Destination Unreachable - Communication Administratively Prohibited"
},
"04": "Source Quench",
"05": {
"00": "Redirect - Datagram for the Network",
"01": "Redirect - Datagram for the Host",
"02": "Redirect - Datagram for the TOS & Network",
"03": "Redirect - Datagram for the TOS & Host"
},
"08": "Echo",
"09": "Router Advertisement",
"0a": "Router Selection",
"0b": {
"01":"Time Exceeded - Time to live exceeded in Transit",
"02":"Time Exceeded - Fragment Reassembly Time Exceeded"
},
"0c": {
"00": "Parameter Problem - Pointer indicates the error",
"01": "Parameter Problem - Missing a Required Option",
"02": "Parameter Problem - Bad Length"
},
"0d": "Timestamp",
"0e": "Timestamp Reply",
"0f": "Information Request",
"10": "Information Reply",
"11": "Address Mask Request",
"12": "Address Mask Reply",
"1e": "Traceroute"
}
這是我的 json 檔案，我想從“03”->“00”中獲取，但是，我不知道如何到達那里
f = open('icmp.json', )
data = json.load(f)
print(data[type, code]) #i was also trying data[type[code]] or data[type][code]
但不為我作業？:D 請幫忙
uj5u.com熱心網友回復：
加載json時，它是python中的字典。你可以像這樣得到你的物品：
f = open('icmp.json', )
data = json.load(f)
print(data['03']['00'])

將我的 json 檔案更改為此有效 :) Thx all for your response
