I'm trying something but I ran into a problem ( `NameError: name 'pole_a_wid' is not defined` )
This is my code:

```py
    import random
    #Random Pole Height
    list = [11, 21, 9, 23, 13, 19, 27, 7]
    random_pole_wid = random.choice(list)
    if random_pole_wid == "11":
        pole_a_wid = 11
        pole_b_wid = 21
    elif random_pole_wid == "21":
        pole_a_wid = 21
        pole_b_wid = 11
    elif random_pole_wid == "9":
        pole_a_wid = 9
        pole_b_wid = 23
    elif random_pole_wid == "23":
        pole_a_wid = 23
        pole_b_wid = 9
    elif random_pole_wid == "13":
        pole_a_wid = 13
        pole_b_wid = 19
    elif random_pole_wid == "19":
        pole_a_wid = 19
        pole_b_wid = 13
    elif random_pole_wid == "27":
        pole_a_wid = 27
        pole_b_wid = 7
    elif random_pole_wid == "7":
        pole_a_wid = 7
        pole_b_wid = 27

    print(pole_a_wid,pole_b_wid)

```

And this is the error that I get:

```
print(pole_a_wid,pole_b_wid) NameError: name 'pole_a_wid' is not defined 

```
