Python - Return values from a function

Question

I have this config file:

[test]
one: value1
two: value2

This function return items, values from section test of config file, but when I call the function only return first item (one, value1).

def getItemsAvailable(section):
    for (item, value) in config.items(section):
        return (item, value)

I call the getItemsAvailable() with this function:

def test():
    item, value = getItemsAvailable('test')
    print (item, value)

I guess that I should create a list on getItemsAvailable() function, and return the list for read the values on test() function, true?

Any suggestions?

Thanks!!

Use a list comprehension. Change

for (item, value) in config.items(section):
    # the function returns at the end of the 1st iteration
    # hence you get only 1 tuple. 
    # You may also consider using a generator & 'yield'ing the tuples
    return (item, value)

to

return [(item, value) for item, value in config.items(section)]

And concerning your test() function:

def test():
    aList = getItemsAvailable('test')
    print (aList)

Use a generator function:

def getItemsAvailable(section):
    for (item, value) in config.items(section):
        yield (item, value)

And get the items like this:

def test():
    for item, value in getItemsAvailable('test'):
        print (item, value)
