Example 1: what is a tuple in 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'
Example 2: tuples in python
my_tuple = 3, 4.6, "dog"
print(my_tuple)
# tuple unpacking is also possible
a, b, c = my_tuple
print(a) # 3
print(b) # 4.6
print(c) # dog
Example 3: tuples
#!/usr/bin/python
tup1 = (12, 34.56);
tup2 = ('abc', 'xyz');
# Following action is not valid for tuples
# tup1[0] = 100;
# So let's create a new tuple as follows
tup3 = tup1 + tup2;
print tup3;
Example 4: py tuple
# Different types of tuples
# Empty tuple
my_tuple = ()
print(my_tuple) # ()
# Tuple having integers
my_tuple = (1, 2, 3)
print(my_tuple) # (1, 2, 3)
# tuple with mixed datatypes
my_tuple = (1, "Hello", 3.4)
print(my_tuple) # (1, 'Hello', 3.4)
# nested tuple
my_tuple = ("mouse", [8, 4, 6], (1, 2, 3))
print(my_tuple) # ('mouse', [8, 4, 6], (1, 2, 3))
