Python 脚本 - 询问用户他们想要使用多少个 IP 地址，然后将该输入用于循环脚本？

Answer 1

每当您发现自己为变量编号时，通常可以用列表和循环替换该代码。循环将防止您一遍又一遍地重复相同的语句。此外，如果您想访问列表中的特定条目，您可以随时为其编制索引。 items[1] 在各个方面都类似于 item1，只是您现在可以使用变量代替索引。

import subprocess
import os

total_length = 5
ip_addresses = []
events = []
##Get IP of devices connected
while len(ip_addresses) < total_length:
    ip_addresses.append(input("Enter the IP address you wish to test in the form xxx.xxx.xxx.xxx: "))

while len(events) < total_length:
    # Set i to the length of events before we push our new entry, so that it references the last entry in the list
    i = len(events)
    ##GET THE EVENT TYPE OF EACH RCU
    os.system("adb -s " +(ip_addresses[i])+ " shell getevent -c 1")
    events.append(input("Enter the event value (ex. event6, event7, event8, ect.):  "))

count = 0
counts = []

firstDisplays = []
while len(firstDisplays) < total_length:
    # Set i to the length of first displays before we push our new entry, so that it references the last entry in the list
    i = len(firstDisplays)
    firstDisplays.append(subprocess.getoutput("adb -s "+(ip_addresses[i])+" shell cat /sys/class/display/mode"))
    print("{}/// Display Mode/// {}".format(ip_addresses[i], firstDisplays[i]))

while count<100: #[ $n -le 5 ]
  count += 1

for i in range(0, total_length):
  # Set i to the length of our lists before we push our new entries, so that it references the last entries in the lists
  ip_address = ip_addresses[i]
  event = events[i]
  print('SWITCHING TO HDMI-1 INPUT\n')
  subprocess.getoutput("adb -s " +(ip_address)+ " shell sendevent /dev/input/"+(event)+" 4 4 787201;sendevent /dev/input/"+(event)+" 1 240 1;sendevent /dev/input/"+(event)+" 0 0 0;sendevent /dev/input/"+(event)+" 4 4 787201;sendevent /dev/input/"+(event)+" 1 240 0;sendevent /dev/input/"+(event)+" 0 0 0")
