Python Exercise: Check if a set is a subset of another set
Python sets: Exercise-10 with Solution
Write a Python program to check if a set is a subset of another set.
Sample Solution:
Python Code:
print("Check if a set is a subset of another set, using comparison operators and issubset():\n")
setx = set(["apple", "mango"])
sety = set(["mango", "orange"])
setz = set(["mango"])
print("x: ",setx)
print("y: ",sety)
print("z: ",setz,"\n")
print("If x is subset of y")
print(setx <= sety)
print(setx.issubset(sety))
print("If y is subset of x")
print(sety <= setx)
print(sety.issubset(setx))
print("\nIf y is subset of z")
print(sety <= setz)
print(sety.issubset(setz))
print("If z is subset of y")
print(setz <= sety)
print(setz.issubset(sety))
Sample Output:
Check if a set is a subset of another set, using comparison operators and issubset(): x: {'mango', 'apple'} y: {'mango', 'orange'} z: {'mango'} If x is subset of y False False If y is subset of x False False If y is subset of z False False If z is subset of y True True

Python: Tips of the Day
Returns True if there are duplicate values in a flat list, False otherwise
Example:
def tips_duplicates(lst): return len(lst) != len(set(lst)) x = [2, 4, 6, 8, 4, 2] y = [1, 3, 5, 7, 9] print(tips_duplicates(x)) print(tips_duplicates(y))
Output:
True False
