How to check if a Specific Item is present in the Set in Python


How to check if a Specific Item is present in the Set in Python ?

Answer

To check if a specific item is present in a Set in Python, you can use the in keyword.



✐ Examples

1 Check if Item is Present

In this example,

  1. We define a Set named my_set containing elements of a specific type.
  2. We use the in keyword to check if a specific item is present in the Set.
  3. The in keyword returns True if the item is present in the Set, otherwise it returns False.
  4. Finally, we print the result to standard output.

Python Program

# Define Set with items
my_set = {"apple", "banana", "orange", "grape", "melon"}

# Check if item is present
item = "banana"
is_present = item in my_set

# Print result
print(f'Is {item} present in the Set? {is_present}')

Output

Is banana present in the Set? True

2 Check if Item is Not Present

In this example,

  1. We define a Set named my_set containing elements of a specific type.
  2. We use the in keyword to check if a specific item is not present in the Set.
  3. The in keyword returns False if the item is not present in the Set.
  4. Finally, we print the result to standard output.

Python Program

# Define Set with items
my_set = {"apple", "banana", "orange", "grape", "melon"}

# Check if item is not present
item = "peach"
is_not_present = item not in my_set

# Print result
print(f'Is {item} not present in the Set? {is_not_present}')

Output

Is peach not present in the Set? True

Summary

In this tutorial, we learned How to check if a Specific Item is present in the Set in Python language with well detailed examples.
