Final answer:
After executing the code, L1, L2, and L3 will have specific values.
Step-by-step explanation:
After executing the given code, the values of L1, L2, and L3 will be:
 
- L1: [1, 2, 3, 4, 5, 6]
- L2: [1, 2, 3, 4, 5, 6]
- L3: [3, 4, 5, 'a', 'b', 'c']
 The code first assigns 
L3
 a slice of 
L1
 and a slice of 
L2
. Then, 
L2
 is assigned the value of 
L1
 and the last element, 'e', is removed from 
L2
. Finally, 6 is appended to 
L1
 resulting in the updated values.
