# Python: Check if a given value is present in a set or not

## Python sets: Exercise-16 with Solution

Write a Python program to check if a given value is present in a set or not.

Visual Presentation:

Sample Solution:

Python Code:

``````# Create a set 'nums' with elements 1, 3, 5, 7, 9, and 11.
nums = {1, 3, 5, 7, 9, 11}

# Print a message to indicate the original set 'nums'.
print("Original set (nums): ", nums, "\n")

# Test if the number 6 exists in 'nums' and print the result.
print("Test if 6 exists in nums:")
print(6 in nums)

# Test if the number 7 exists in 'nums' and print the result.
print("Test if 7 exists in nums:")
print(7 in nums)

# Test if the number 11 exists in 'nums' and print the result.
print("Test if 11 exists in nums:")
print(11 in nums)

# Test if the number 0 exists in 'nums' and print the result.
print("Test if 0 exists in nums:")
print(0 in nums)

# Test if the number 6 is not in 'nums' and print the result.
print("\nTest if 6 is not in nums")
print(6 not in nums)

# Test if the number 7 is not in 'nums' and print the result.
print("Test if 7 is not in nums")
print(7 not in nums)

# Test if the number 11 is not in 'nums' and print the result.
print("Test if 11 is not in nums")
print(11 not in nums)

# Test if the number 0 is not in 'nums' and print the result.
print("Test if 0 is not in nums")
print(0 not in nums)
```
```

Sample Output:

```Original sets(nums):  {1, 3, 5, 7, 9, 11}

Test if 6 exists in nums:
False
Test if 7 exists in nums:
True
Test if 11 exists in nums:
True
Test if 0 exists in nums:
False

Test if 6 is not in nums
True
Test if 7 is not in nums
False
Test if 11 is not in nums
False
Test if 0 is not in nums
True
```
