Description

Hello,
I need to retrieve alarm event from host, but i can't access to the "from" attribute.
Alarm event example :

`(vim.event.AlarmStatusChangedEvent) {
      dynamicType = <unset>,
      dynamicProperty = (vmodl.DynamicProperty) [],
      key = xxxxxx,
      chainId = xxxxx,
      createdTime = 20xx-xx-xxTxx:xx:xx.864999Z,
      userName = '',
      datacenter = (vim.event.DatacenterEventArgument) {
         dynamicType = <unset>,
         dynamicProperty = (vmodl.DynamicProperty) [],
         name = 'xxxxxx',
         datacenter = 'vim.Datacenter:datacenter-xxx'
      },
      computeResource = (vim.event.ComputeResourceEventArgument) {
         dynamicType = <unset>,
         dynamicProperty = (vmodl.DynamicProperty) [],
         name = 'Cluster P-SciMotors',
         computeResource = 'vim.ClusterComputeResource:xxxxx'
      },
      host = (vim.event.HostEventArgument) {
         dynamicType = <unset>,
         dynamicProperty = (vmodl.DynamicProperty) [],
         name = 'xxxxxxxxxxxxx',
         host = 'vim.HostSystem:xxxxx'
      },
      vm = <unset>,
      ds = <unset>,
      net = <unset>,
      dvs = <unset>,
      fullFormattedMessage = "Alarm 'Host memory usage' on xxxx from Green to Yellow",
      changeTag = <unset>,
      alarm = (vim.event.AlarmEventArgument) {
         dynamicType = <unset>,
         dynamicProperty = (vmodl.DynamicProperty) [],
         name = 'Host memory usage',
         alarm = 'vim.alarm.Alarm:alarm-4'
      },
      source = (vim.event.ManagedEntityEventArgument) {
         dynamicType = <unset>,
         dynamicProperty = (vmodl.DynamicProperty) [],
         name = 'Datacenters',
         entity = 'xxxxxxxx'
      },
      entity = (vim.event.ManagedEntityEventArgument) {
         dynamicType = <unset>,
         dynamicProperty = (vmodl.DynamicProperty) [],
         name = 'xxxxxxxxxxx',
         entity = 'xxxxxx'
      },
      from = 'green',
      to = 'yellow'

   }`

my code to retrieve alarm's info :

for alarm in event_res:
    if hasattr(alarm, "alarm"):
      print(alarm.from)

result :
File "C:\xxxxx\xxxxx\xxxxxx\xxxx-xxx\test.py", line 125 print(alarm.from) ^ SyntaxError: invalid syntax

"from" is a reserved keyword in python

thx for reading

Research direction

Start with the event_res loop in test.py around the reported line 125 and inspect how the alarm event exposes its fields. Verify the Python syntax and attribute access for the event's from value, then confirm the retrieved value matches the alarm event shown in the issue without raising a SyntaxError.
