This article mainly introduces how to find the most common elements in the list using Python, and provides three common methods for your reference, for more information about how to find the most common element in the list using Python, see the example in this article. We will share this with you for your reference. The details are as follows:
Assuming that a list contains various elements, you need to count the number of each element and print out the first three elements that most often appear. List:
The code is as follows:
Word_list = ["is", "you", "are", "I", "am", "OK", "is", "OK", "She ", "is", "OK", "is", "I"]
Method 1 (conventional method ):
>>> word_counter ={}>>> for word in word_list: if word in word_counter: word_counter[word] +=1 else: word_counter[word] = 1>>> popular_word =sorted(word_counter, key = word_counter.get, reverse = True))>>> top_3 = popular_word[:3]>>> top_3['is', 'OK', 'I']
Method 2: Applicable to Python2.7
>>> from collections import Counter>>> c = Counter(word_list)>>> c.most_common(3)
Method 3:
>>> counter ={}>>> for i in word_list: counter[i] = counter.get(i, 0) + 1>>> sorted([ (freq,word) for word, freq in counter.items() ], reverse=True)[:3][(4, 'is'), (3, 'OK'), (2, 'I')]
