Question

我在python中有一个线程代码，我需要找出执行功能a与再次执行相同功能之间的时间。怎么做？我尝试使用timeit模块，但结果错误

最小代码为

def abc1 ():
  process 
def abc2():
  process 
def abc3:
  process

如上所述，有许多线程化的函数，我想确定函数abc1是否在时间0执行，然后在多少时间后再次执行abc1

如果您对装饰器和线程安全性的概念感到满意，请使用以下解决方案：

import time
import threading

# Let us define a list that stores the execution start times
exec_history = []
# Define a lock which allows safe access to this list
list_lock = threading.Lock()

# Define a decorator, which will "log" the execution of its function to the list
def log_func_call(fn):
    def wrapper(*args, **kwargs):
        with list_lock:
            # Note down which function and when it was called.
            # Alternatively, you can also log to a file or terminal, etc.
            exec_history.append((fn, time.time()))  
        return fn(*args, **kwargs)

    return wrapper

# Decorate whichever method you want to track
@log_func_call
def abc1():
    pass

@log_func_call
def abc2():
    pass

exec_history将在调用任何函数时以及其开始时间进行更新。这是您要找的吗？
