Adding pipe symbol in Python command

Question

I am trying to write a script to copy files from one flash drive to another using Python along with Zenity UI. Variables Sorz_star and Desz contains path to two flash drives.

subprocess.call('cp -R %s %s |zenity --progress --text "Copying" --pulsate --auto-close'%(Sorz_star,Desz), shell=True)

This works fine in terminal but when I use this command in my copy.py file it shows this error

sh: 2: Syntax error: "|" unexpected

I bet one or both of those ends with a newline. Use `.strip()` on them to remove it. — David K. Hess, Mar 23 '15 at 02:07

One or both of the substituted variables probably ends with a newline. Use .strip() on them to remove it.
