Subject: [PATCH] TypeError: expected string or bytes-like object

when I try to run using style_mix like given example I got
TypeError: expected string or bytes-like object .
I print the input:s of num_range function. I find  it may get a list and raise the error.
I haven't found out when it happened (num_range function get a list),but simply change makes it work.
