I am new to Python just for my own interest. I am taking the introductory course from eDX. I would like to understand why when I run the following code, the reverse function will reverse both the reverse_fours list and the original all_fours
all_fours = fours + more_fours
reverse_fours = all_fours
print("All ",all_fours)
print("Reverse ",reverse_fours)
reverse_fours.reverse()
print("All ",all_fours)
print("Reverse ",reverse_fours)
