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

Please let me know how to remove this error

Here is the code which gives the error...

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

you left out the line number from that error message, and the code you
posted doesn't even compile:

File "chand.py", line 67
elif arg[0] == "ADD_OPTIONAL_PARAM" :
^
IndentationError: unindent does not match any outer indentation level

(from what I can tell, you never assign to g_opt_list in that script, so it
sure looks like you didn't post the right version of your program. but
instead of reposting the code, look at the line Python told you to look
at; if you cannot figure out how to fix that, try to reduce the script to
a few lines before posting the code)

It seems that your variable names got mixed up.
