在 python 中从初始定义的时间后延迟命令

Question

我正在尝试从初始执行时间开始延迟命令。换句话说，我想要一个开始时间点，其余命令将参考该开始时间点延迟。示例：

print("start")

# command that delays for a minute since the start
print("it's been a 1 min")

# command that delays for n minute since the start
print("it's been n min")

我正在尝试从 sleep() 切换，但没有找到适合我需要的东西。感谢任何帮助。

Answer 1

import time
initial_time = int(time.time()) #frame of reference in seconds

def delta_sleep(s):
    """
    Parameters:
        s: seconds since elapsed to sleep until
    """
    if int(time.time()) > initial_time + s:
        # check if the delta time has already passed
        return
    else:
        # find time needed to sleep to reach the specified param 's'
        needed_sleep = (initial_time+s) - int(time.time())
        time.sleep(needed_sleep)

# example

print("The program has started")

delta_sleep(5)

print("Five seconds have passed")

delta_sleep(8)

print("8 seconds have passed")

delta_sleep(1) # does not sleep at all

在 python 中从初始定义的时间后延迟命令

Delay commands after defined time from initial in python
