Question

我对我的脚本有两个问题，如何将其输出到我请求的文件中。我问这个因为它无限循环，当我取消脚本并显示文件时它是空的。另外，如果必须取消脚本输入任何内容，如何使用分配的变量？谢谢！

import subprocess
import datetime
#open results file and assign to results variable, add append rights
results = open("results.txt", "a")
#Run until stopped
while 1:
#split the blah variable by line
#Run tshark command 100 times, then restart script. Assign to blah variable
    blah = subprocess.check_output(["tshark -i mon0 -f \"subtype probe-req\" -T fields -e wlan.sa -e wlan_mgt.ssid -c 20"], shell=True)
splitblah = blah.split("\n")
#repeat  for each line, ignore first line since it contains headers
for value in splitblah[:-1]:
    #split each line by tab delimiter
    splitvalue = value.split("\t")
#Assign variables to split fields
MAC = str(splitvalue[1])
SSID = str(splitvalue[2])
time = str(datetime.datetime.now())
#write and format output to results file
Results.write(MAC+" "+SSID+" "+time+"\r\n")

你应该在你的while陈述中加上一个条件，否则程序（确实）永远不会停止。

此外，在someFileObject.write函数调用后，数据不一定立即写在磁盘上，您需要调用someFileObject.flush来确保数据。

Python没有写出来
