Python: Compute the difference between two lists

Sample Solution :-

Python Code :

from collections import Counter
color1 = ["red", "orange", "green", "blue", "white"]
color2 = ["black", "yellow", "green", "blue"]
counter1 = Counter(color1)
counter2 = Counter(color2)
print("Color1-Color2: ",list(counter1 - counter2))
print("Color2-Color1: ",list(counter2 - counter1))

Sample Output: 

Color1-Color2:  ['red', 'white', 'orange']                                                                    
Color2-Color1:  ['black', 'yellow']

Python: Tips of the Day

Returns True if the provided function returns True for every element in the list, False otherwise:

Example:

def tips_every(lst, fn=lambda x: x):
  return all(map(fn, lst))

print(tips_every([2, 4, 3], lambda x: x > 1))
print(tips_every([1, 2, 3]))

Output:

True
True
