Hello,

I am trying to make a program for 3D modelling with "programming".And
I want make my own program commands,

for example when user type code in my program:

"<<koristiti>> OS"- (THIS IS MY IMAGINARY EXAMPLE OF KEYWORD),

my program must write this code in some user file, but my

program must read this command like: "import os".How

can I do something like that??
