Python 中序列中第二常见的词语有哪些?
给定一个字符串,我们的任务是找出第二个重复的单词。我们在这里使用 Counter(iterator) 创建了一个字典,其中包含词语作为键,其频率作为值。
算法
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.
示例代码
# To print Second most repeated word in a sequence in Python from collections import Counter defsecondrepeatation(A): # Convert list into dictionary con = Counter(A) res = sorted(con.values(), reverse=True) maxi = res[1] for (key, val) in con.items(): if val == maxi: print("Second most repeated word ::>",key) return # Driver program if __name__ == "__main__": A=list() #create user defined list n=int(input("Enter the size of the List ::")) print("Enter the word ::") for i in range(int(n)): k=input("") A.append(k) secondrepeatation(A) # call function
输出
Enter the size of the List ::4 Enter the word :: aa bb aa cc Second most repeated word ::> bb
