"file" is a reserved word! This is why it's not working for you!
Change "file" to something else, like "result" for example.
Here:
>>> src = 'file1.c'
>>> dst = 'file2.c'
>>> result = "result"
>>> command_string = "diff -u %s %s > %s.patch" % (src, dst, result)
>>> command_string
'diff -u file1.c file2.c > result.patch'
Is this what you want?
