Example 1: create a named tuple python
>>> from collections import namedtuple
>>> Person = namedtuple('Person', 'first_name last_name zip_code')
>>> p1 = Person('Joe', 'Schmoe', '93002')
>>> p1.first_name
'Joe'
>>> p1[0]
'Joe'
>>> p1.zip_code
'92002'
>>> len(p1)
3
>>> type(p1)
<class '__main__.Person'>
>>>
Example 2: 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 3: Python Ordered Dictionary
from collections import OrderedDict
# Remembers the order the keys are added!
x = OrderedDict(a=1, b=2, c=3)
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))
Example 5: python collections
list = [1,2,3,4,1,2,6,7,3,8,1]
Counter(list)
