String object has no attribute "append"

[Matt Graves]

I receive this error while toying around with Functions...

def pulldata(speclist,speccolumn):
    with open('profiles.csv', 'r') as f:
              reader = csv.reader(f)
              for column in reader:
                 (speclist).append(column[('speccolumn')])

pulldata(speclist = 'numbers', speccolumn = "0")


>Traceback (most recent call last):

I'm getting the error because it should say "numbers.append", but it is reading it as "(speclist).append".

This is my first time playing with functions, so be gentle.
