统计字符串每个单词出现的次数。
def word_amount(sentence):
split_list = sentence.split()
dict_result = {}
for word_name in split_list:
if word_name not in dict_result.keys():
dict_result[word_name] = 1
else:
dict_result[word_name] += 1
return dict_result
if __name__ == '__main__':
sentence = "I can because i think i can"
dict_result = word_amount(sentence)
print(dict_result)
或者：
if __name__ == '__main__':
sentence = "I can because i think i can"
result = {word: sentence.split().count(word) for word in set(sentence.split())}
print(result)
或者：
from collections import Counter
if __name__ == '__main__':
sentence = "I can because i think i can"
counts = Counter(sentence.split())
print(counts)
