Python threading.Timer - repeat function every 'n' seconds

Python threading.Timer - repeat function every 'n' seconds

In Python, you can use the threading.Timer class to schedule a function to be executed repeatedly every n seconds. Here's how you can do it:

import threading def my_function(): # Define the code you want to execute here print("Hello, World!") # Create a Timer that repeats the function every 5 seconds interval = 5 # Adjust this to set the interval in seconds timer = threading.Timer(interval, my_function) # Start the timer timer.start() # To stop the timer, you can call timer.cancel() when you're done # timer.cancel()

In this example:

  1. We define a function my_function() that contains the code you want to execute repeatedly.

  2. We create a threading.Timer object named timer with an interval of 5 seconds. You can adjust the interval variable to set the desired time between each execution.

  3. We start the timer using timer.start(). This will execute my_function() every n seconds (in this case, every 5 seconds).

  4. If you want to stop the timer at any point, you can call timer.cancel(). Uncomment the timer.cancel() line when you want to stop the timer.

Make sure to replace the my_function() content with the actual code you want to execute repeatedly.

Examples

    import threading def repeat_function(interval, function): # Define the function to be repeated def repeat(): function() # Call the repeat function after 'interval' seconds threading.Timer(interval, repeat).start() # Start the initial timer threading.Timer(interval, repeat).start() # Example usage def my_function(): print("Hello, world!") # Repeat my_function every 5 seconds repeat_function(5, my_function) 
      import threading def periodic_task(interval, function): # Define the function to be executed periodically def execute_periodically(): function() # Schedule the next execution after 'interval' seconds threading.Timer(interval, execute_periodically).start() # Start the initial timer threading.Timer(interval, execute_periodically).start() # Example usage def my_task(): print("This task repeats every 10 seconds.") # Schedule my_task to execute every 10 seconds periodic_task(10, my_task) 
        import threading def periodic_execution(interval, function): # Define the function to be executed periodically def execute_periodically(): function() # Schedule the next execution after 'interval' seconds threading.Timer(interval, execute_periodically).start() # Start the initial timer threading.Timer(interval, execute_periodically).start() # Example usage def my_periodic_function(): print("This function executes every 3 seconds.") # Execute my_periodic_function every 3 seconds periodic_execution(3, my_periodic_function) 
          import threading def recurring_task(interval, function): # Define the function to be executed as a recurring task def execute_recurring(): function() # Schedule the next execution after 'interval' seconds threading.Timer(interval, execute_recurring).start() # Start the initial timer threading.Timer(interval, execute_recurring).start() # Example usage def my_recurring_task(): print("This task recurs every 7 seconds.") # Schedule my_recurring_task to run every 7 seconds recurring_task(7, my_recurring_task) 
            import threading def repeated_execution(interval, function, delay=0): # Define the function to be executed repeatedly with a delay def execute_with_delay(): function() # Schedule the next execution after 'interval' seconds threading.Timer(interval, execute_with_delay).start() # Start the initial timer with a delay threading.Timer(delay, execute_with_delay).start() # Example usage def my_function_with_delay(): print("This function repeats with a 2-second delay.") # Repeat my_function_with_delay every 5 seconds with a 2-second delay repeated_execution(5, my_function_with_delay, delay=2) 
              import threading class TaskScheduler: def __init__(self): self.tasks = {} def schedule_task(self, task_name, interval, function): def execute_task(): function() self.tasks[task_name] = threading.Timer(interval, execute_task) self.tasks[task_name].start() self.tasks[task_name] = threading.Timer(interval, execute_task) self.tasks[task_name].start() def cancel_task(self, task_name): if task_name in self.tasks: self.tasks[task_name].cancel() del self.tasks[task_name] # Example usage scheduler = TaskScheduler() scheduler.schedule_task("task1", 5, lambda: print("Task 1 executed")) scheduler.schedule_task("task2", 10, lambda: print("Task 2 executed")) 
                import threading def repeated_function(interval, function): # Define the function to be executed repeatedly def execute_repeatedly(): function() # Schedule the next execution after 'interval' seconds threading.Timer(interval, execute_repeatedly).start() # Start the initial timer threading.Timer(interval, execute_repeatedly).start() # Example usage def my_repeated_function(): print("This function repeats every 4 seconds.") # Execute my_repeated_function every 4 seconds repeated_function(4, my_repeated_function) 
                  import threading def repeating_function(interval, function): # Define the function to be called repeatedly def call_repeatedly(): function() # Schedule the next call after 'interval' seconds threading.Timer(interval, call_repeatedly).start() # Start the initial timer threading.Timer(interval, call_repeatedly).start() # Example usage def my_repeating_function(): print("This function repeats every 6 seconds.") # Call my_repeating_function every 6 seconds repeating_function(6, my_repeating_function) 
                    import threading def execute_task_every(interval, function): # Define the function to execute the task every 'interval' seconds def execute_periodically(): function() # Schedule the next execution after 'interval' seconds threading.Timer(interval, execute_periodically).start() # Start the initial timer threading.Timer(interval, execute_periodically).start() # Example usage def my_task_to_execute(): print("This task executes every 8 seconds.") # Execute my_task_to_execute every 8 seconds execute_task_every(8, my_task_to_execute)
