Equal Sets

Overview:

For two sets to be equal, they simply have to contain the same elements - it doesn't matter what order they're in.

Unfortunately in Python, comparing two lists using == will only produce True if the elements are in the same order, which is not what we want!

There's no built-in function to compare differently-ordered lists, so you'll be writing it here by leveraging your knowledge of sets.

You will practice these programming concepts we've covered in class:

• Functions
• Sets

Deliverables

One .py file with code that solves the problem.

Requirements:

Write a function that takes two lists and returns True if they have the same elements, even if they aren't in the same order.

Here is an example using lists. Try running this normally:

fruits = ['orange', 'pear', 'kiwi', 'apple', 'banana']

fruits_copy = ['orange', 'pear', 'kiwi', 'apple', 'banana']

fruits_reordered = ['pear', 'apple', 'kiwi', 'orange', 'banana']

print("Copy comparison", fruits == fruits_copy)
print("Reordered comparison", fruits == fruits_reordered)

Above, the Reordered comparison prints False. Convert the above example from lists to sets. Does the output of the two print statements change? Why?
