Python Counter elements - Get all the items from the Counter object

The elements() of a Counter object returns what can make all the items of it.

from collections import Counter

c = Counter(pen=3, book=2)

c1 = c.elements()
c2 = list(c1)

print(c1)  # <itertools.chain object at 0x10dba6310>
print(c2)  # ['pen', 'pen', 'pen', 'book', 'book']

c1 is an iterable so can be iterated in for statement.

from collections import Counter

c = Counter(pen=3, book=2)

c1 = c.elements()

for i in c1:
    print(i)

# pen
# pen
# pen
# book
# book
