Tuple

 

#Sample Tuple

thistuple = ("apple", "banana", "cherry")

print(thistuple)

('apple', 'banana', 'cherry')

#Create Tuple With One Item

#To create a tuple with only one item, you have to add a comma after the item, otherwise Python will not recognize it as a tuple.

​

thistuple = ("apple",)

print(type(thistuple))

​

#NOT a tuple

thistuple = ("apple")

print(type(thistuple)) 

<class 'tuple'>
<class 'str'>

#Change Tuple Values

#Convert the tuple into a list to be able to change it

x = ("apple", "banana", "cherry")

y = list(x)

y[1] = "kiwi"

x = tuple(y)

​

print(x) 

​

#Add Items

thistuple = ("apple", "banana", "cherry")

y = list(thistuple)

y.append("orange")

thistuple = tuple(y)

​

#Another Way

thistuple = ("apple", "banana", "cherry")

y = ("orange",)

thistuple += y

​

print(thistuple)

​

#Remove Items

thistuple = ("apple", "banana", "cherry")

y = list(thistuple)

y.remove("apple")

thistuple = tuple(y)

​

#The del keyword can delete the tuple completely

thistuple = ("apple", "banana", "cherry")

del thistuple

print(thistuple)

('apple', 'kiwi', 'cherry')
('apple', 'banana', 'cherry', 'orange')

#Unpack Tuples

#Count
