I've got an "invalid syntax" error with this code in python. Help me find a remedy? [SOLVED]
<p>In the <code>def(pentagon):</code> chunk I've named a variable "<code>first</code>". However, this causes an "invalid syntax" error. What's wrong? I've tried naming it other things, ranging from single letters to combinations of lower/capital letters like "preArea".</p>

<pre><code>def display():
    print('This program will tell you the area some shapes')
    print('You can choose between...')
    print('1. rectangle    2. triangle')
    print('3. circle       4. pentagon')
    print('5. rhombus      6. trapezoid')

def shape():
    shape = int(input('What shape do you choose?'))
    if shape == 1: rectangle()
    elif shape == 2: triangle()
    elif shape == 3: circle()
    elif shape == 4: pentagon()
    elif shape == 5: rhombus()
    elif shape == 6: trapezoid()
