Tuples in Python are similar to lists, but they are immutable, meaning that their values cannot be changed after they are created.
To create a tuple, you can use parentheses and separate the values with commas. For example:
my_tuple = (1, 2, 3)You can also create a tuple using the built-in tuple() function, like so:
my_list = [1, 2, 3]
my_tuple = tuple(my_list)You can access the elements of a tuple using indexing, just like you would with a list. For example:
print(my_tuple[0]) # Output: 1You can also use negative indexing to access elements from the end of the tuple.
You can use the len() function to find the number of elements in a tuple, and the in keyword to check if a certain value is present in the tuple.
You can’t modify the element of tuple after its creation, if you want to change the value of tuple, you need to create a new tuple with modified values.
You can also use tuple packing and unpacking to assign multiple values to variables at once.
x, y, z = (1, 2, 3)
print(x, y, z) # Output: 1 2 3Tuples are useful when you want to use multiple values as a single entity, such as in a function that returns multiple values. It is also useful when you want to use a collection of items that should not be changed throughout the program.
In summary, a tuple is a collection of ordered and immutable elements, which can be accessed and iterated through like a list. They are useful when you want to use multiple values as a single entity and also when you want to use a collection of items that should not be changed throughout the program.
