Python中的子流程添加变量

import subprocess
subprocess.call('Schtasks /create /sc  ONCE  /tn  Work  /tr C:\work.exe /st 15:42 /sd 13/10/2010')

我希望能够在上面的命令中设置变量。变量是时间'15：42'在15和42之间分开，日期'13 / 10/2010'在日，月和年中分开任何想法？

Answer 1

使用% formatting构建命令字符串。

>>> hour,minute = '15','42'
>>> day,month,year = '13','10','2010'
>>> command = 'Schtasks /create /sc  ONCE  /tn  Work  /tr C:\work.exe /st %s:%s /sd %s/%s/%s'
>>> command % (hour,minute, day,month,year)
'Schtasks /create /sc  ONCE  /tn  Work  /tr C:\\work.exe /st 15:42 /sd 13/10/2010'
>>> subprocess.call( command % (hour,minute, day,month,year) )
>>>

Answer 2


import subprocess 
time = "15:42"
date = "13/10/2010"
# you can use these variables anyhow take input from user using raw_iput()
subprocess.call('Schtasks /create /sc ONCE /tn Work /tr C:\work.exe /st '+time+' /sd '+date)

Answer 3

Python在字符串上使用format方法具有高级字符串格式化功能。例如：

>>> template = "Hello, {name}. How are you today, {date}?"
>>> name = "World"
>>> date = "the fourteenth of October"
>>> template.format(name=name, date=date)
'Hello, World. How are you today, the fourteenth of October?'

您可以使用datetime模块中的strftime获取时间和日期：

>>> import datetime
>>> now = datetime.datetime.now()
>>> now.strftime("%A %B %Y, %I:%M:%S")
'Wednesday October 2010, 02:54:30'

Answer 4

import time

subprocess.call(time.strftime("Schtasks /create /sc  ONCE  /tn  Work  /tr C:\work.exe /st %H:%M /sd %d/%m/%Y"))

如果您想更改时间，可以将其设置为时间对象并使用它。
