You probably missed that other hint where Fredrik Lunddh told you to somewhat reduce the script's size. > Please find below the code which compiles. Please let me know how to > resolve this warning message..!! > SyntaxWarning: name 'g_opt_list' is used prior to global declaration This warning occurs if a global variable is used before it is declared as such: >>> def f(): ... v = 42 ... global v ... <stdin>:1: SyntaxWarning: name 'v' is assigned to before global declaration This kind of code is dangerous because a casual reader might think that v is a local variable. You can avoid the warning -- and the source of confusion -- by moving the declaration to before the variable's first usage (I prefer the top of the function): >>> def f(): ... global v ... v = 42 ... In your script things are even more messed up. You declare g_opt_list twice: >>> def f(): ... global v ... v = 42 ... global v ... <stdin>:1: SyntaxWarning: name 'v' is assigned to before global declaration Now that you understand the cause of the warning it is time to proceed to yet another effbot hint: You never rebind the global variable g_opt_list and therefore do not need the global g_opt_list statement at all.
