嗨这个代码有问题
currentdirectory = os.getcwd()
processfile=currentdirectory+"\ClientProcessList.txt"
print processfile
os.system('WMIC /OUTPUT: %s PROCESS get Caption,Commandline,Processid') % processfile
错误:
os.system('WMIC /OUTPUT: %s PROCESS get Caption,Commandline,Processid') % pr
ocessfile
TypeError: unsupported operand type(s) for %: 'int' and 'str'
我甚至试过这个:
os.system('WMIC /OUTPUT: '+processfile+' PROCESS get Caption,Commandline,Processid')
错误:
Invalid Global Switch.
答案 0 :(得分:0)
格式化字符串的语法是:
"some string %s" % "the string"
但在()
:
%
some_function("some string %s") % "the string" # this will try to apply
# the % operator to the value
# returned by the function.
由于您要将格式应用于作为参数传递的字符串,因此应该是:
some_function("some string %s " % "the string")
在你的情况下:
os.system('WMIC /OUTPUT: %s PROCESS get Caption,Commandline,Processid' % processfile)
