Python: Find the elements in a given set that are not in another set

Python sets: Exercise-19 with Solution

Write a Python program to find elements in a given set that are not in another set.

Visual Presentation:

Sample Solution:

Python Code:

``````# Create sets 'sn1' and 'sn2' with different elements.
sn1 = {1, 2, 3, 4, 5}
sn2 = {4, 5, 6, 7, 8}

# Print a message to indicate the original sets.
print("Original sets:")
print(sn1)
print(sn2)

# Print a message to find the difference between 'sn1' and 'sn2' using the 'difference()' method.
print("Difference of sn1 and sn2 using difference():")

# Use the 'difference()' method to find and print the elements that are in 'sn1' but not in 'sn2'.
print(sn1.difference(sn2))

# Print a message to find the difference between 'sn2' and 'sn1' using the 'difference()' method.
print("Difference of sn2 and sn1 using difference():")

# Use the 'difference()' method to find and print the elements that are in 'sn2' but not in 'sn1'.
print(sn2.difference(sn1))

# Print a message to find the difference between 'sn1' and 'sn2' using the '-' operator.
print("Difference of sn1 and sn2 using - operator:")

# Use the '-' operator to find and print the elements that are in 'sn1' but not in 'sn2'.
print(sn1 - sn2)

# Print a message to find the difference between 'sn2' and 'sn1' using the '-' operator.
print("Difference of sn2 and sn1 using - operator:")

# Use the '-' operator to find and print the elements that are in 'sn2' but not in 'sn1'.
print(sn2 - sn1)
```
```

Sample Output:

```Original sets:
{1, 2, 3, 4, 5}
{4, 5, 6, 7, 8}
Difference of sn1 and sn2 using difference():
{1, 2, 3}
Difference of sn2 and sn1 using difference():
{8, 6, 7}
Difference of sn1 and sn2 using - operator:
{1, 2, 3}
Difference of sn2 and sn1 using - operator:
{8, 6, 7}
```
