warning when doubly liked list is defined globally

[chand]

Hi.,

In my api.py file 'g_opt_list' is defined globally
g_opt_list =[[],[],[],[],[],[],[]]

when I run the py file, I am getting the Following Error

SyntaxWarning: name 'g_opt_list' is used prior to global declaration
SyntaxWarning: name 'layers' is used prior to global declaration

Please let me know how to remove these warnings.

I found that commenting 'g_opt_list' initialisation in "NEW" command
removes this warning message. But my requirement is that i want to
reset g_opt_list to empty list, whenever "NEW" command is called.


Here is the code which gives the error...

I have removed most of the unwanted code to reduce the size.

Let me know exact reason for this warning and how to remove these
warnings..




import os,sys,re,string,math
g_opt_list =[[],[],[],[],[],[],[]]
SIG_STANDARD_HOME = "/home/chandras/SIGNALLING_STANDARD/ANSI_SS7/"
symbols=['(',')','{','}','[',']','.']
reverse_symbols=['<','>','~']
layers=['MTP3','SCCP','IOS','CDTAPM2','CDTAPC2','ISUP','IS-41D-SQA']

GUI_API_COMMAND_LIST = [
"NEW",
"ADD_OPTIONAL_PARAM",
]

Message_obj = Message()
def Process_GUI_Command(arg):
global Message_obj
global filename
out_file = file('/tmp/te.txt', 'w+')

if arg[0] == "NEW" :
global g_opt_list
for i in range(0,len(g_opt_list)):
g_opt_list = []
return layerList

elif arg[0] == "ADD_OPTIONAL_PARAM" :
global g_opt_list
global layers
global index
message_name = ""
add_delete_flag = 0

param_name = optional_parameter_name
g_opt_list[int(index)].append(optional_parameter_name)
