PYTHON ADVANCED - 06: COLLECTIONS

 HERE, WE WILL LEARN ABOUT COLLECTIONS:

NOTE: TRY ALL  TYPES/CODES

#collections : counter, namedtuple, orderedict, defaultdict, deque

# from collections import Counter

# a = "aaaaaaaaaabbbbbbbbbbbbcccccccc"

# mycounter = Counter(a)

# print(mycounter)

# print(mycounter.items())

# print(mycounter.keys())

# print(mycounter.values())

# print(mycounter.most_common(3))

# print(mycounter.most_common(3)[0])

# print(list(mycounter.elements()))

# from collections import namedtuple

# Point = namedtuple('Point', 'x,y')

# pt = Point(1,-4)

# print(pt.x , pt.y)

# from  collections import OrderedDict

# ordered_dict = OrderedDict()

# ordered_dict['a'] = 1

# ordered_dict['b'] = 2

# print(ordered_dict)

# from collections import defaultdict

# d = defaultdict(int)

# d['a'] = 1

# d['c'] = 2

# d['b'] = 3

# print(d['c'])

from collections import deque

d = deque()

d.append(1)

d.append(2)

d.appendleft(3)

print(d)

# d.popleft()

# print(d)

# d.clear()

# print(d)

d.extendleft([4,5,6])

print(d)

d.rotate(1)

print(d)

d.rotate(-1)

print(d)
