如何看待在Visual代码中运行我的程序所需的时间？

Question

有没有一种方法可以查看脚本在VS代码中执行/完成所用的时间？

我在找这样的信息：

Program finished in 30ms

Answer 1

利用‘时间’

当脚本开始时：

import time
start_time = time.time()

do something # here your actual code/routine

print("Process finished --- %s seconds ---" % (time.time() - start_time))

Answer 2

您可以创建一个简单的装饰函数来计时您的函数。

import time

def decoratortimer(decimal):
    def decoratorfunction(f):
        def wrap(*args, **kwargs):
            time1 = time.monotonic()
            result = f(*args, **kwargs)
            time2 = time.monotonic()
            print('{:s} function took {:.{}f} ms'.format(f.__name__, ((time2-time1)*1000.0), decimal ))
            return result
        return wrap
    return decoratorfunction

@decoratortimer(2)
def callablefunction(name):
    print(name)
print(callablefunction('John'))

我建议使用time.monotonic(它是一个不会倒退的时钟)来提高精确度。

要实现这一点，最简单的方法是单纯地编码编程时间。perf_counter提供了time函数的最高精度。

from time import perf_counter, sleep
def main():
    sleep(5)

start_time = perf_counter()

main() # Function to measure

passed_time = perf_counter() - start_time

print(f"It took {passed_time}") # It took 5.007398507999824
