+# Day 6:
+## Tuple
+A tuple is a collection of different data types which is ordered and unchangeable(immutable). Tuples are written with round brackets,(). Once a tuple is created, we can not change its values. We can not add, insert, remove a tuple because it is not modifiable (mutable). Unlike list, tuple has few methods. Methods related to tuple:
+* tuple(): to create an empty tuple
+* count(): to count the number of a specified item in a tuple
+* index(): to find the index of a specified item in a tuple
+* + operator: to join two or more tuples and to create new tuple
+### Creating Tuple
+
+* Empty tuple: Creating an empty tuple
+```py
+# syntax
+empty_tuple = () 
+# or using the tuple constructor
+empty_tuple = tuple()
+```
+* Tuple with initial values
+```py
+# syntax
+tpl = ('item1', 'item2','item3')
+```
+* 
+```py
+fruits = ('banana', 'orange', 'mango', 'lemon')
+```
+### Tuple length
+We use the *len()* method to get the length of a tuple.
+```py
+# syntax
+tpl = ('item1', 'item2', 'item3')
+len(tpl)
+```
+### Accessing tuple items
+* Positive Indexing
+Similar to the list data type we use positive or negative indexing to access tuple items.
+![Accessing tuple items](images/tuples_index.png)
+
+```py
+# Syntax
+tpl = ('item1', 'item2', 'item3')
+first_item = tpl[0]
+second_item = tpl[1]
+```
+```py
+fruits = ('banana', 'orange', 'mango', 'lemon')
+first_fruit = fruits[0]
+second_fruit = fruits[1]
+last_index =len(fruits) - 1
+last_fruit = fruits[las_index]
+```
+* Negative indexing
+Negative indexing means beginning from the end, -1 refers to the last item, -2 refers to the second last and the negative of the list length refers to the first item.
+![Tuple Negative indexing](images/tuple_negative_indexing.png)
+```py
+# Syntax
+tpl = ('item1', 'item2', 'item3','item4')
+first_item = tpl[-4]
+second_item = tpl[-3]
+```
+```py
+fruits = ('banana', 'orange', 'mango', 'lemon')
+first_fruit = fruits[-4]
+second_fruit = fruits[-3]
+last_fruit = fruits[-1]
+```
+### Slicing tuples
+We can slice out a sub tuple by  specifying a range of indexes where to start and where to end in the tuple, the return value will be a new tuple with the specified items.
+
+* Range of Positive Indexes
+
+```py
+# Syntax
+tpl = ('item1', 'item2', 'item3','item4')
+all_items = tpl[0:4]         # all items
+all_items = tpl[0:]         # all items
+middle_two_items = tpl[1:3]  # does not include item at index 3
+```
+```py
+fruits = ('banana', 'orange', 'mango', 'lemon')
+all_fruits = fruits[0:4]    # all items
+all_fruits= fruits[0:]      # all items
+orange_mango = fruits[1:3]  # doesn't include item at index 3
+orange_to_the_rest = fruits[1:]
+```
+
+* Range of Negative Indexes
+
+```py
+# Syntax
+tpl = ('item1', 'item2', 'item3','item4')
+all_items = tpl[-4:]         # all items
+middle_two_items = tpl[-3:-1]  # does not include item at index 3
+```
+```py
+fruits = ('banana', 'orange', 'mango', 'lemon')
+all_fruits = fruits[-4:]    # all items
+orange_mango = fruits[-3:-1]  # doesn't include item at index 3
+orange_to_the_rest = fruits[-3:]
+```
+### Changing tuples to list
+We can change tuples to list and list to tuple. Tuple is immutable if we want to modify a tuple we should change to a list.
+```py
+# Syntax
+tpl = ('item1', 'item2', 'item3','item4')
+lst = list(tpl)
+```
+```py
+fruits = ('banana', 'orange', 'mango', 'lemon')
+fruits = list(fruits)
+fruits[0] = 'apple'
+print(fruits)     # ['apple', 'orange', 'mango', 'lemon']
+fruits = tuple(fruits)
+print(fruits)     # ('apple', 'orange', 'mango', 'lemon')
+```
+### Checking an item in a list
+We can check an item if it exists in a list or not using *in*, it returns boolean.
+```py
+# Syntax
+tpl = ('item1', 'item2', 'item3','item4')
+'item2' in tpl # True
+```
+```py
+fruits = ('banana', 'orange', 'mango', 'lemon')
+'orange' in fruits # True
+'apple' in fruits # False
+fruits[0] = 'apple'
+```
+### Joining tuples
+We can join two or more tuples using + operator
+```py
+# syntax
+tpl1 = ('item1', 'item2', 'item3')
+tpl2 = ('item4', 'item5','item6')
+tpl3 = tpl1 + tpl2
+```
+```py
+fruits = ('banana', 'orange', 'mango', 'lemon')                    
+vegetables = ('Tomato', 'Potato', 'Cabbage','Onion', 'Carrot')
+fruits_and_vegetables = fruits + vegetables 
+```
+### Deleting tuple
+It is not possible to remove a single item in a tuple but it is possible to delete the tuple itself using *del*.
+```py
+# syntax
+tpl1 = ('item1', 'item2', 'item3')
+del tpl1
+
+```
+```py
+fruits = ('banana', 'orange', 'mango', 'lemon') 
+del fruits                  
+```
+

+## Exercises: Day 6
+1. Create an empty tuple
+2. Create a tuple containing name of your sisters and your brothers
+3. Join brothers and sisters tuples and assign it to siblings
+4. How many siblings do you have ?
+5. Modify the siblings tuple and add the name of your father and mother and assign it to family_members
+6. Unpack siblings and parents from family_members
+7. Create a fruits, vegetables and animal products tuples. Join the three tuples and assign it to a variable called food_stuff. 
+8. Slice out the middle item or items from the food_staff list
+9. Slice out the first three items and the last three items from food_staff list
+10. Delete the food_staff list completely
+11. Check if an item exist in a tuple:
+* Check if 'Estonia' is a nordic country
+* Check if 'Iceland' is a nordic country
+  ```py
+  nordic_countries = ('Denmark', 'Finland','Iceland', 'Norway', 'Sweden')
+  ```
