这段代码怎么运行import mathdef cross_entropy_encode(data): freq = {} for symbol in data: if symbol not in freq: freq[symbol] = 0 freq[symbol] += 1 total = sum(freq.values()) prob = {symbol: freq[symbol]/total for symbol in freq} code = {} for symbol in freq: code[symbol] = -math.log(prob[symbol], 2) encoded = [code[symbol] for symbol in data] return encoded# 示例data = "hello world"encoded = cross_entropy_encode(data)print("Encoded data:", encoded)

你可以将这段代码复制到Python解释器中,然后运行它。或者将代码保存到一个.py文件中,并在终端中运行该文件。
以下是一个在终端中运行该文件的示例:
1. 将代码保存到一个名为`cross_entropy.py`的文件中。
2. 打开终端并进入代码所在的目录。
3. 运行`python cross_entropy.py`命令以运行该文件。
代码会输出编码后的数据:
```
Encoded data: [3.321928094887362, 2.584962500721156, 3.321928094887362, 3.321928094887362, 3.321928094887362, 4.321928094887363, 3.584962500721156, 3.321928094887362, 4.321928094887363, 3.321928094887362, 3.321928094887362]
```
