문자열이 주어지면 우리의 임무는 두 번째 반복되는 단어를 찾는 것입니다. 여기서 우리는 단어를 키로 포함하고 빈도를 값으로 포함하는 사전을 생성하기 위한 Counter(iterator)입니다.
알고리즘
Step 1: Create user define list. Step 2: Then convert list into a dictionary. Step 2: Next get the values and sort them in descending order. Step 3: Then the second element is the second largest value. Step 4: Next again traverse whole dictionary and display key whose value is equal to second largest element.

# To print Second most repeated word in a sequence in Python from collections

# Convert list into dictionary
con = Counter(A)

for (key, val) in con.items():

for i in range(int(n)):

secondrepeatation(A) # call function
출력
