🖥️ Access Items from a Tuple in Python (Indexing, Slicing)
You can access individual items in a tuple using an index in square brackets, or using the unpacking method. Note that Tuple indexing in Python starts from 0. The indices for the elements in a tuple are illustrated as below:
my_tuple = ('red', 'green', 'blue', 'yellow', 'black')
red, green, blue, yellow, black = my_tuple
print(my_tuple[0])
# Prints red
print(my_tuple[2])
# Prints blue
○ Negative Indexing in Python
You can access a tuple by negative indexing as well. Negative indexing counts backward, from the end of the tuple. So, my_tuple[-1] refers to the last item, my_tuple[-2] is the second-last item, and so on. But, be careful not to access an element outside of your tuple, or you would get an “IndexError: tuple index out of range”.
my_tuple = ('red', 'green', 'blue', 'yellow', 'black')
print(my_tuple[-1])
# Prints black
print(my_tuple[-2])
# Prints yellow
○ Tuple Slicing in Python
Okay, But How you would access a range of items, from your tuple? You need to slice a tuple using the slicing operator. Tuple slicing is similar to List slicing, in which you will specify the start and end indexes with an optional step size. Each parameter can be positive or negative indexing values. Do you want to discover more about Python slicing Operators? Please, Check out our Blog, and the video about Lists in Python.
my_tuple = ('a', 'b', 'c', 'd', 'e', 'f')
print(my_tuple[2:5]) # ('c', 'd', 'e')
print(my_tuple[0:2]) # ('a', 'b')
print(my_tuple[3:-1]) # ('d', 'e')
