I think you're close, just a little out of order. Think about it this way:
- first you need to create a string containing the command, using the
string formatting operations.
'/bin/touch %s' % i
will do that. Note the %s is part of the string, and the % i is part of
the formatting expression.
- next you pass the formatted string to os.system(). So the whole
formatting expression has to go inside the parentheses - the value of
the expression is passed to os.system():
os.system('/bin/touch %s' % i)
You could also do this without calling out to the system - just open a
file for writing and close it again:
open(i, 'w').close()
