Thread Properties

Describing t.name

  • The name property refers to the thread name
  • This is a string that is used for identification
  • We can change the name if desired

Describing t.ident

  • The ident property refers to a unique identification number tied to the thread
  • If the thread has not yet started, the value is None

Describing t.daemon

  • The daemon property refers to the daemonic status
  • It is a boolean value
  • The thread must be set to a daemon prior to calling start
  • The initial value is inherited from daemonic status of the creating thread
  • The entire program exists when non active non-daemon threads are left
  • All programs have a main thread that represents the initial thread of control
  • This main thread is not daemonic
