找出句子中每个单词的出现次数，并使用地图将其打印出来

import matplotlib.pyplot as plt

# 输入句子
sentence = "This is a sample sentence. This sentence is a sample."

# 分词
words = sentence.split()

# 创建字典
word_count = {}

# 统计单词出现次数
for word in words:
    if word in word_count:
        word_count[word] += 1
    else:
        word_count[word] = 1

# 打印单词出现次数
for word, count in word_count.items():
    print(f"{word}: {count}")

# 绘制地图
x = list(word_count.keys())
y = list(word_count.values())

plt.bar(x, y)
plt.xlabel('Words')
plt.ylabel('Count')
plt.title('Word Count')
plt.show()
