How Can I Implement Precise Time Delays in Python?

Effective Approaches for Time Delays in Python

When working with Python scripts, there may arise a need to incorporate time delays to control the flow and timing of events. This question explores methods for implementing time delays in Python.

One effective approach is to use the time module. By importing the module and using the sleep() function, it's possible to halt script execution for a specified duration. For instance, the following code snippet delays execution for 2.5 seconds:

import time

time.sleep(2.5)

For more precise timing, you can use the sleep function with a fractional argument. This allows you to specify delays with decimal precision.

Another approach for recurring time delays is to employ a loop that checks the current time and compares it to a target time. Once the target time is reached, the desired action is executed. Here's an example:

import time

while True:
    current_time = time.time()
    if current_time >= target_time:
        # Perform the desired action
        target_time += 60  # Increment the target time by 1 minute
        time.sleep(0)  # Yield to other processes

In this example, the script continuously checks the current time and executes the desired action every minute. The time.sleep(0) call ensures that the script yields to other processes, allowing them to run without being blocked by the continuous loop.
