Visualizing Your Code

When you're first learning about data structures such as lists, it helps to visualize how python is working with the information in your program. pythontutor.com is a graet tool for seeing how python keeps track of the information in a list. Try running the following code on pythontutor.com and then run your own code.

#Build a list and print the items in the list
dogs = []
dogs.append('willie')
dogs.append('hootz')
dogs.append('peso')
dogs.append('goblin')

for dog in dogs:
 print("Hello " + dog + "!")
print("I love these dogs!")

print("\nThese were my first two dogs:")
old_dogs = dogs[:2]
for old_dog in old_dogs:
 print(old_dog)

del dogs[0]
dogs.remove('peso')
print(dogs)
