Python Data Structures (Tuple)
Hello guys! I will mention the tuple which is data structures in this article. I will code on Visual Studio Code also I will show you on Github. Okay, let’s start!
Tuple
Tuple has many features. These are,
- Tuple can be accessed by index,
- Ordered,
- Tuples cannot be modified, so items cannot be added or deleted after they are created.
- () is defined in parentheses, and elements are separated by commas.
- It may contain different types of data.
- It can have two items with the same value. It can be duplicate data.
I would like to give some examples related to tuples.
Indexes in Tuple
I want to show you how indexes work in tuples.
- If we want to create an empty tuple, then we should do,
tuple = ()
- This example shows from zero to five indexes. Here we see that zero is included, but 5 is not.
my_tuple = (0,1,2,3,4,5,6,7,8,9)
print(my_tuple[:5])
Output:
(0, 1, 2, 3, 4)- To find which index “Gilbert” is in the tuple we should do,
my_tuple = ("Anne with an E", "Gilbert", "Rosemary")
print(my_tuple.index("Gilbert"))
Output:
1- Searching,
my_tuple = (1,2,3,4,1,2,7,6,8,2)
print(my_tuple.index(2,4,7)) # searches for 2 between 4 and 7
Output:
5- Changing,
Tuples cannot be modified. Tuples cannot be changed. If there is a list in the tuple, we can only change it within the list.
mix_tuple = ("Selin", 303, True, [1,2,3])mix_tuple[3][0] = 8print(mix_tuple)
Output:
('Selin', 303, True, [8, 2, 3])
If we want to change elements in a tuple then,
Firstly, we should change the tuple to list.
my_tuple = (1,2,3,4)
print(my_tuple)temp_list = list(my_tuple)
print(temp_list)
Output:
(1, 2, 3, 4)
[1, 2, 3, 4]
For example, we wanted to change the third index to “Bootcamp”,
temp_list[3] = "Bootcamp"
print(temp_list)
Output:
[1, 2, 3, 'Bootcamp']In conclusion, we changed to list to a tuple again.
my_tuple = tuple(temp_list)
print("Type", type(my_tuple))
print(my_tuple)
Output:
Type <class 'tuple'>
(1, 2, 3, 'Bootcamp')Copying Tuple
I explained to give an example.
my_tuple = (1,2,3,4)
my_tuple2 = my_tuple
print(my_tuple2)
Output:
(1, 2, 3, 4)my_tuple = (1,2,3,4)
tuple3 = my_tuple2 + my_tuple
print(tuple3)
Output:
(1, 2, 3, 4, 1, 2, 3, 4)
Attention!
I would like to give some important information about tuples. If you want to create a tuple you should be careful when creating it.
my_tuple = ("Selin")
my_tuple1 = ("Selin",)print(type(my_tuple))
print(type(my_tuple1))
Output:
<class 'str'>
<class 'tuple'>
If you don’t put a comma, it doesn’t perceive as a tuple.
