Thank you guys for the prompt and helpful response.

modules.

I can understand the point that global variables tends to mess up
programs.

Assume that I have 10 parameters need to pass to the function. If
these parameters are fixed, I can use another module to store these 10
parameters, and import to the module, as suggested by jean-michel. But
what if these 10 parameters will be changed in the main program?
Passing the variable to the function as a parameter suggested by Rami
will certainly do, but I am wondering weather there are other ways.
What you'd like to code it?
Thank you very much!
