我無法獲得動態打印 output 的腳本

Question

運行以下腳本時，不會打印任何內容，但當我按 ctrl+c 並結束任務時，會打印完整的 output。 我想以一種方式使列表的每一行都動態打印，因為腳本本身正在運行我正在嘗試運行的 function 是...`

`def passive_scan(interface):
    result=[]
    ip=[]
    packets = []
    mode="p"
    sniff(iface="eth0", prn=filter_packets(packets),timeout= 10000)
    for p in packets:
        if p[0]["ARP"].op==2:
            src_mac=p[0]["ARP"].hwsrc
            src_ip=p[0]["ARP"].psrc
            ip.append(src_ip)
            dict={"mac":src_mac,"ip":src_ip}
            result.append(dict)
    for client in result:
        client["count"]=countOf(ip,client["ip"])
    print_result(result,mode)`

` 我正在使用的 output 打印 function 是......

```
`print("Interface: "+interface+"\t\tMode: Passive\t\t\tFound "+str(len(list))+" hosts")        
print("----------------------------------------------------------------------------")
print("MAC\t\t\t\tIP\t\t\tHost Activity")
print("----------------------------------------------------------------------------")
for client in list:
    print(client["mac"] + "\t\t" + client["ip"]+"\t\t"+str(client["count"]))`
```

```
`


i was able to properly format the output but to get that to print i have to end the task than only it prints



the required output should look like..

這是sniff()的預期行為，它是一個阻塞 function。

“ sniff() function 會無限期地監聽，直到用戶中斷。”

您應該使用AsyncSniffer ： https://scapy.readthedocs.io/en/latest/usage.html#asynchronous-sniffing
