Tuples in python are similar as Lists.
But tuples are immutable where as
lists are mutable. That means you can not change the values of tuple once assigned
Tuples can
contain any type of data like lists
Tuples can be created by using parentheses () with comma separated objects and
using tuple() built-in function.
We can pass an iterable to tuple()
function to create a tuple object.
mytuple = () # Empty tuple
mytuple = tuple() # Empty tuple
print(type(mytuple)) # prints <class 'tuple'>
mytuple = (10, ) # Single value or item to tuples
print(mytuple) # prints (10,)
mytuple = (1, 2, 3, 4, "hello", [7, 8]) # Any data type
print(mytuple) # prints (1, 2, 3, 4, "hello", [7, 8])
list1 = [1, 2, 3, 4, 5] # prints (1, 2, 3, 4, 5)
print(tuple(list1)) # List converted to tuple
To create a single valued tuple you need to use a comma after the item.object like this (10,
)
Because without comma like (10), it will be considered as the data type
of individual object not tuple
t = (10)
print(t)
print(type(t))
Like lists, the values of a tuple can be accessed busing indexes
mytuple = ("pythoneasy", 2016, "english", ".com", 1, 2, 3, 4)
print(mytuple[1]) # prints 2016 at index 1
print(mytuple[2]) # prints english at index 2
print(mytuple[5]) # prints 2 at index 5
mytuple = ("pythoneasy", 2016, "english", ".com", 1, 2, 3, 4)
print(mytuple[-6]) # prints "english"
print(mytuple[-1]) # prints 4, the last elementmytuple[-1] always provides the last value.
mytuple = ("pythoneasy", 2016, "english", ".com", 1, 2, 3, 4)
print(mytuple[1:4]) # prints (2016, 'english', '.com')
print(mytuple[slice(1, 4)]) # prints (2016, 'english', '.com')
