python模块中的Linux脚本

Question

I'm doing a project on automation and we are using the MFRC522 library, but some of our equipment isn't working as intended. This has led us on an awkward detour for scripting and such. We are able to get the UID's of the NFC tag, and now we want to create a linux script that will reference these numbers.

The long and short of it is: is it possible to make a linux script run from a python module?

ex:

if status == MIFAREReader.MI_OK:
   print "Card read UID:" +str(backData[0])+ "," + \
          str(backData[1]) +"," + str(backData[2])  + \
           ","+str(backData[3])+","+str(backData[4])

here is where I put the code for getting the UID to the file

here is where I'd like to put the code to link the linux script

Maybe you could use the subprocess module. You can do things like this:

import subprocess
subprocess.call('ls | wc -l', shell=True)

Important to note that using the shell flag presents some security concerns. That's in the docs linked above.
