compare two lists to find differences python code example

Example 1: 2 list difference python

list1 = [1, 2, 4]
list2 = [4, 5, 6]

set_difference = set(list1) - set(list2)
list_difference = list(set_difference)

print(list_difference)

#result
[1,2]

Example 2: compare two list in python

>>> s = ['a','b','c']   
>>> f = ['a','b','d','c']  
>>> ss= set(s)  
>>> fs =set(f)  
>>> print ss.intersection(fs)   
   **set(['a', 'c', 'b'])**  
>>> print ss.union(fs)        
   **set(['a', 'c', 'b', 'd'])**  
>>> print ss.union(fs)  - ss.intersection(fs)   
   **set(['d'])**
