Python tuple

x=("ankit", "manu", "sachin")
print(x)

Output

('ankit', 'manu', 'sachin')

tuple datatype type()

<class 'tuple'>

access tuples items

access items from tuple (tuple slicing).

slicing

x=("ankit", "manu", "sachin")
print(x[0])
#-1 indexing from last value
print(x[-1])

Output

ankit
sachin

range of indexing

slicing of tuple
frist character have zero(0) index noumber

slicing

x=("ankit", "manu", "sachin")
print(x[0:2])
print(x[-3:-1])
print(x[1:])
print(x[:3])

• List:tuple is written in square brackets [], collection of mutavle and ordered values. allow duplicate.
• Dict:tuple is written in curly brackets {}, collection of unordered and mutable values. not allow duplicate.
• Set:tuple is written in curly brackets {}, collection of unordered , unindexed and immutable values. not allow duplicate.
