I am a complete newbie to Python (and programming in general) and I
have no idea what I'm missing. Below is a script that I am trying to
work with and I cannot get it to work. When I call the final print
function, nothing prints. However, if I print within the individual
functions, I get the appropriate printout.
Am I missing something??? Thanks in advance!!!!

# Global variable

It'd be best if you used different names for global scope than you do
inside your functions. It won't change how this case works, but at
least it'd be clearer what's happening. And sometimes you can get an
unintended side effect when you use the same name for two different
variables.
In function gen_header(), you take an argument, and return a modified
version of it. But the call to it never uses the return value. If you
want to make any changes to the global value, you'd do something like this:
sample_string = gen_header(sample_string)
sample_string = gen_nia(sample_string)
print(sample_string)
