In this Python set program, we will check whether two sets are disjoint or not with the help of the below-given steps.
What is set?
Sets are used to store multiple items in a single variable.
The set is one of 4 built-in data types in Python used to store collections of data.
It is an unordered collection data type that is iterable, mutable and has no duplicate elements.
Disjoint set: A pair of sets that do not have any common element are called disjoint sets.
Two sets are disjoint:
Method 1 : Using in-built function
Steps to solve the program
1. Create two sets using {}.
2. Add some elements in the sets.
3. Check if two sets are disjoint using isdisjoint() function.
4. Print the output.
a = {1,2,4,5}
b = {7,8,9}
print("Original set1: ",a)
print("Original set2: ",b)
print("Are two sets dis-joint: ",a.isdisjoint(b))
Output :
Original set1: {1, 2, 4, 5}
Original set2: {8, 9, 7}
Are two sets dis-joint: True
Method 2 : Using Logic
Steps to solve the program
1. Create two sets using {}.
2. Add some elements in the sets.
3. Create a count variable and assign its value equal to 0.
4. Use a for loop to iterate over elements in the second set.
5. Use an if statement to check whether the element is in the first set.
6. If yes then add 1 to the count variable.
7. Use an if-else statement to check whether the value of the count variable is greater than 0.
8. If no then two sets are disjoint, else yes.
9. Print the respective output.
a = {1,2,4,5}
b = {7,8,9}
print("Original set1: ",a)
print("Original set2: ",b)
count = 0
for ele in b:
if ele in a:
count+=1
if count > 0:
print("Are two sets dis-joint: False")
else:
print("Are two sets dis-joint: True")
Output :
Original set1: {1, 2, 4, 5}
Original set2: {8, 9, 7}
Are two sets dis-joint: True
