Write a Python program to count the occurrences of each word in a given sentence. Sample Solution: Python Code: # Define a function named word_count that takes one argument, 'str'.defword_count(str):# Create an
word_count_dict = defaultdict(int) for w in text.split(" "): word_count_dict[w] += 1 # 方法二:Counter(或者直接 word_counter = Counter(text.split(" "))) from collections import Counter word_count_dict = Counter() for w in text.split(" "): word_count_dict[w] += 1 print('m...
most common word: [('I', 3), ('the', 2), ('of', 2), ('do', 2), ('to', 2), ('multiple', 1), ('in', 1), ('way', 1), ('us', 1), ('occurrences', 1)] 1. 其他的一些应用例子: # Count Characters print(Counter('abccccccddddd')) # Count List elements print(C...

count(x) 计算deque中个数等于x的元素。 3.2 新版功能. extend(iterable) 扩展deque的右侧,通过添加iterable参数中的元素。 extendleft(iterable) 扩展deque的左侧,通过添加iterable参数中的元素。注意,左添加时,在结果中iterable参数中的顺序将被反过来添加。
