[Tutor] Global Variables

[Joseph Fennell]

Quick introduction,  I'm Joseph Fennell, and I've been playing with python
for the past 6 years (primarily in the interpreter) and have finally gotten
started on a full project and I've run into a small problem.  I have defined
some modules, and when I import them into the page I want to use them on
after I run the program it tells me the variable I'm trying to pass through
them is not defined.

I assume that it's because the variable is considered local and the imported
functions are not technically local to that document.

The code is to pass the contents of a database through to filter by name and
quantity and as follows

=================================================

cHandler.execute("SELECT * FROM table")

#sets results from above to nl

nl = cHandler.fetchall()

dn = raw_input("User input: ")

nl2 = []

dname()
########
def dname():
    global nl
    for ndc in nl:
        if ndc[1] == dn:
            nl2.append(ndc,)
        else:
            continue
#########
tuple(nl2) = nl2

qtysrch()
#########
def qtysrch():
    global nl2
    for ndc in nl2:
        if ndc[7] == 0:
            continue
        else:
            print ndc


Any help I can get with this problem would be greatly appreciated.


Thanks
