python - 一直试图让用户输入分钟，以便 Python 可以将其转换为命令行的秒

Question

minute = 60
shutdown = ("Shutdown")
log_off = ("Log Off")
restart = ("Restart")
import time
time.sleep(1)
option = input("What would you like to do today?\n Shutdown \n Restart \n Log Off\n")
if option == shutdown:
    time.sleep(1)
    print("You have selected to", shutdown)
    time.sleep(0.5)
    time_shutdown = input("How long do you want until the machine shuts down?(in minutes)")
    number = int(time_shutdown)
    #So at this point I want the minutes converted to seconds
    minutes = number * minute
    #So this should then convert the minutes into seconds
    import subprocess
    subprocess.call(["shutdown.exe", "-f", "-s", "-t", minutes])
    print("Your command has been processed...")
    time.sleep(1.5)
    number = int(time_shutdown)
    minutes = number / minute
    print("Your machine will close down in", minutes,"minutes.")


Traceback (most recent call last):
File "C:\Python34\test.py", line 23, in <module>
subprocess.call(["shutdown.exe", "-f", "-s", "-t", minutes])
File "C:\Python34\lib\subprocess.py", line 537, in call
with Popen(*popenargs, **kwargs) as p:

File "C:\Python34\lib\subprocess.py", line 663, in list2cmdline
needquote = (" " in arg) or ("\t" in arg) or not arg
TypeError: argument of type 'int' is not iterable

我迫切需要一些关于如何使其发挥作用的建议，因为我一整天都在试图弄清楚。我希望我没有错过一些我应该放在那里的愚蠢的东西。

有人可以帮我吗？

Answer 1

您的错误似乎是由 subprocess.call 尝试将您的 分钟 参数解释为字符串引起的。尝试改变

subprocess.call(["shutdown.exe", "-f", "-s", "-t", minutes])

至

subprocess.call(["shutdown.exe", "-f", "-s", "-t", str(minutes)])
