给定一个字符串。我们的任务是在给定的字符串中找到第一个重复的单词。要实现此问题,我们使用Python集合。从集合中,我们可以获得Counter()
方法。
Repeatedword(n) /* n is the string */ Step 1: first split given string separated by space into words. Step 2: now convert the list of words into a dictionary. Step 3: traverse list of words and check which the first word has frequency >1
# To Find the first repeated word in a string from collections import Counter def repeatedword(n): # first split given string separated by space into words w = n.split(' ') con = Counter(w) for key in w: if con[key]>1: print ("REPEATED WORD IS ::>",key) return # Driver program if __name__ == "__main__": n=input("Enter the String ::") repeatedword(n)
输出结果
Enter the String ::We are all peaceful soul and blissful soul and loveful soul happy soul REPEATED WORD IS ::> soul
