尝试将字符串参数传递给函数,然后在整个函数中将其用作变量。因为某些原因,当我试图这样做时,它不起作用。我做错什么了?
import subprocess
def printerSetup(printer):
subprocess.call(r'Cscript c:/windows/System32/Printing_Admin_Scripts/en-US/Prnport.vbs -a -r "'printer'.print.web.com" -h "' + printer + '.print.web.com" -o raw')
if printer == 'saturn' or printer == 'jupiter' or printer == 'neptune':
subprocess.call(r'rundll32 printui.dll, PrintUIEntry /if /b "' + printer + '" /f w:\printers\toshibae3511\eng\est_c2.inf /r "' + printer + '.print.web.com" /m "TOSHIBA e-STUDIO Color PS3"')
if printer == 'mercury':
subprocess.call(r'rundll32 printui.dll, PrintUIEntry /if /b "' + printer + '" /f w:\printers\dell1720\drivers\print\dell1720\DKABJ740.inf /r "' + printer + '.print.web.com" /m "Dell Laser Printer 1720dn"')
printerSetup("neptune")
printerSetup("mercury")
编辑了程序。尝试运行此新程序后,出现以下错误:
C:\Python27\Projects\Printer Setup>c:\python27\python.exe saturn.py
File "saturn.py", line 3
subprocess.call(r'Cscript c:/windows/System32/Printing_Admin_Scripts/en-US/P
rnport.vbs -a -r "'printer'.print.web.com" -h "' + printer + '.print.web.c
om" -o raw')
^
SyntaxError: invalid syntax
您需要为每个
or
语句指定variable == value
,如下所示:您还忘记了每个
if
语句的尾随冒号。如果您想说“这个变量与这个值列表匹配吗?”,以下内容可能更适合您:
您还需要将变量添加到字符串中-不能只将它们放在相邻的位置:
