[请帮助我获取执行.exe文件或打开.pdf文件所用的时间。提到的代码无济于事

Question

'''这里我尝试在python 3.7中遵循以下代码，但未获取打开pdf文件所用的时间''

start = timeit()
subprocess.Popen(r'C:\Program Files\AcroRD32.exe')
end = timeit()
elapsed_time = end - start

Answer 1

请尝试：

from time import time 
start = time() 
# ... do something 
time_used = round(time() - start)
# this is in seconds, convert if you need 
time_str = f'{time_used//3600}:{str((time_used%3600)//60):0>2}:{str(time_used%60):0>2}'
print(time_str)
