The Timer class in Python is used to create a timer object that can execute a specified function after a specified time interval.<\/p>\n

The main functions of timer are two-fold:<\/p>\n

    \n
  1. Delayed execution of functions: Timer can delay the execution of a specific function and call the function after a specified time interval. This is very useful for scenarios where a function needs to be executed after a certain amount of time, such as scheduled tasks or polling operations.<\/li>\n
  2. Multi-thread processing: Timer extends the Thread class, so it can create a background thread to execute timed tasks. This helps prevent the main thread from being blocked, thus improving the program’s concurrency and responsiveness.<\/li>\n<\/ol>\n

    To use the Timer class, you need to specify two parameters: the time interval and the function to be executed. After creating and starting a Timer object, it will invoke the specified function after the designated time interval.<\/p>\n

    Here is an example code using Timer:<\/p>\n

    import<\/span> threading\r\n\r\ndef<\/span> print_hello<\/span>():\r\n    print<\/span>(\"Hello, world!\"<\/span>)\r\n\r\n# \u521b\u5efa\u4e00\u4e2aTimer\u5bf9\u8c61\uff0c\u95f4\u96942\u79d2\u540e\u8c03\u7528print_hello\u51fd\u6570<\/span>\r\ntimer = threading.Timer(2<\/span>, print_hello)\r\ntimer.start()\r\n<\/code><\/pre>\n
    The above code will print “Hello, world!” after 2 seconds.<\/p>\n","protected":false},"excerpt":{"rendered":"
