Yes. You are passing sample_string into the functions, but not doing
anything with the return value.

The sample_string name is rebound to the parameter now, completely
hiding the global variable, if that's really what you wanted.

Try this:
sample_string = gen_header(sample_string)
sample_string = gen_nia(sample_string)
You could drop the arguments to your functions and use the "global"
keyword to get access to sample_string from within the functions, but
normally that's a bad idea.
