Python - Testing if tuple contains K

In Python, a tuple is an ordered collection of elements enclosed within parentheses. Tuples are immutable, meaning their values cannot be modified once created. To test if a tuple contains a particular element K, you can use the in keyword or the index() method.

Here is an example code snippet demonstrating these methods:

# Sample tuple
my_tuple = (1, 2, 3, 4, 5)

# Testing if tuple contains K using 'in' keyword
if 3 in my_tuple:
    print("Tuple contains element 3")
else:
    print("Tuple does not contain element 3")

# Testing if tuple contains K using 'index()' method
try:
    index = my_tuple.index(6)
    print(f"Tuple contains element 6 at index {index}")
except ValueError:
    print("Tuple does not contain element 6")

In the above code, we first initialize a tuple my_tuple with some elements. We then test if the tuple contains the element 3 using the in keyword. If the element is present, we print a message indicating that the tuple contains it. Otherwise, we print a message stating that the tuple does not contain it.

Next, we test if the tuple contains the element 6 using the index() method. This method searches for the first occurrence of the element in the tuple and returns its index. If the element is not found, it raises a ValueError which we catch using a try-except block. In the except block, we print a message stating that the tuple does not contain the element.

Feel free to modify the tuple and the element being tested according to your requirement.

Remember to enclose the code within proper Python code blocks when sharing it in markdown to maintain formatting and readability.
