tuplein python

# A tuple is a sequence of immutable Python objects. Tuples are # sequences, just like lists. The differences between tuples # and lists are, the tuples cannot be changed unlike lists and # tuples use parentheses, whereas lists use square brackets. tup1 = ('physics', 'chemistry', 1997, 2000); tup2 = "a", "b", "c", "d"; # To access values in tuple, use the square brackets for # slicing along with the index or indices to obtain value # available at that index. tup1[0] # Output: 'physics'

my_tuple = ("hello") print(type(my_tuple)) # <class 'str'> # Creating a tuple having one element my_tuple = ("hello",) print(type(my_tuple)) # <class 'tuple'> # Parentheses is optional my_tuple = "hello", print(type(my_tuple)) # <class 'tuple'>

tuples in python

t = 12345, 54321, 'hello!'
print(t[0])
# output 12345
print(t)
# output (12345, 54321, 'hello!')
# Tuples may be nested:
u = t, (1, 2, 3, 4, 5)
print(u)
# output ((12345, 54321, 'hello!'), (1, 2, 3, 4, 5))
# Tuples are immutable:
# assigning value of 12345 to 88888
t[0] = 88888
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'tuple' object does not support item assignment
# but they can contain mutable objects:
v = ([1, 2, 3], [3, 2, 1])
print(v)
# output ([1, 2, 3], [3, 2, 1])
