计算字符串中出现次数最多的单词(Python)
要计算出现次数最多的单词,可以使用Python中的字典数据结构来统计每个单词出现的次数。下面是一种实现方式:
```python
def count_words(string):
#创建一个空字典来存储单词及其出现次数
word_count = {}
#将字符串拆分成单词列表
words = string.split()
#遍历单词列表,更新单词的出现次数
for word in words:
if word in word_count:
word_count[word] += 1
else:
word_count[word] = 1
#到出现次数最多的单词
max_count = 0
max_word = ""
for word, count in word_count.items():
if count > max_count:
max_count = count
max_word = word
return max_word
#测试
sentence = "I love coding, and coding is my passion. Coding makes me happy!"
most_common_word = count_words(sentence)
print("The most common word is:", most_common_word)
```
说明用法:
该函数`count_words`接受一个字符串作为参数,将其拆分成单词列表。然后使用一个字典`word_count`来存储每个单词以及它们出现的次数。接着,遍历单词列表,更新字典中的计数。最后,出字典中出现次数最多的单词,并将其返回。
