No, I was properly inserting the spaces. When I changed it to a print
statement and executed the resulting output, it worked just fine.
Change it back to os.system() call and it would not work unless I
placed the entire command in the cmd variable.

Seemed very odd to me. Could have been an error I didn't notice and
fixed them I the string to all being stored in the variable, but then
why would the output of the print statement work when I copy and
pasted it?
