local variable 'option' referenced before assignment

[RedSkeleton007]

Actually, the string still doesn't print correctly:

#!/usr/bin/env python3
#BuildYourOwnCDmixName.py

def heavyMetalCDMixName():
    yourName = input("What is your name: ")
    VWL = ["Angry", "Violent", "Crazy", "Dangerous", "Berserk"] #VWL = ViolentWordList
    print("The words in the list include: "
          + "[0]:" + VWL[0] + ", [1]:" + VWL[1] + ", [2]:" + VWL[2] + ", [3]:"
          + VWL[3] + ", [4]:" + VWL[4])
    print("Choose index numbers from [0] to [4] to complete the name for your "
          + str(yourName) + "'s _______ Heavy Metal mix. Enter 100 when you're done.")

    name = (str(yourName) + "'s ")
    mixNameList = []
    mixName = ""

    option = True
    while True:        
        option = int(input("Enter index number to append to your CD mix's name: "))
        if option == 0:
            mixNameList = list(mixName)
            mixNameList.insert(0, VWL[0]) 
            mixName = ''.join(mixNameList)
        elif option == 1:
            mixNameList = list(mixName)
            mixNameList.insert(0, VWL[1]) 
            mixName = ''.join(mixNameList)
        elif option == 2:
            mixNameList = list(mixName)
            mixNameList.insert(0, VWL[2]) 
            mixName = ''.join(mixNameList)
        elif option == 3:
            mixNameList = list(mixName)
            mixNameList.insert(0, VWL[3]) 
            mixName = ''.join(mixNameList)
        elif option == 4:
            mixNameList = list(mixName)
            mixNameList.insert(0, VWL[4])
            mixName = ''.join(mixNameList)
        elif option == 100:            
            print("You named your CD mix: " + name + mixName + " Heavy Metal Mix")
            break
        else:
            print("You must enter a valid index number between 0 and 4 from VML.")
            continue        

def main():
    heavyMetalCDMixName()

main()

But the output of my string is backwards. For example:

Output:
=== RESTART: I:\Python\Python36-32\SamsFavorites\BuildYourOwnCDmixName.py ===
What is your name: Sam
The words in the list include: [0]:Angry, [1]:Violent, [2]:Crazy, [3]:Dangerous, [4]:Berserk
Choose index numbers from [0] to [4] to complete the name for your Sam's _______ Heavy Metal mix. Enter 100 when you're done.
Enter index number to append to your CD mix's name: 0
Enter index number to append to your CD mix's name: 1
Enter index number to append to your CD mix's name: 3
Enter index number to append to your CD mix's name: 100
You named your CD mix: Sam's DangerousViolentAngry Heavy Metal Mix
>>> 

I was expecting "Sam's AngryViolentDangerous Heavy Metal Mix", because that's the order I originally selected them from the VWL list.
What happened?
