Python 使用maketrans/translate从包含字符串的序列中删除标点

我想删除序列中字符串的标点符号

我正在使用python3.6和maketrans，translate函数来实现这一点。然而，它并没有给我想要的结果

代码前有两句话：

Baking cake of straw-bana-choco will take longer than expcted


Please include as much of the following data that is available.< >< >- Cake Type:< >- Flavors:< >- Decoration Type:< >- Icing:< >-

代码后面的句子：

baking cake of strawbanachoco will take longer than expcted


please include as much of the following data that is available   cake type flavors decoration type icing

所以我想知道为什么strawbanachoco不是staw bana choco，似乎代码没有用空格代替-。而在第二种情况下，它似乎是用空格代替标点符号

我没有在上面的代码片段中包含，但我也将所有句子都小写

有没有关于为什么会发生这种情况的建议

谢谢

第二句中没有空格代替。原始字符串中的标点符号字符之间有空格，这些字符只是被保留了下来

有关此操作的详细信息，请参阅。

如果要将每个标点符号替换为空格：

s = """
Baking cake of straw-bana-choco will take longer than expcted
Please include as much of the following data that is available.< >< >- Cake Type:< >- Flavors:< >- Decoration Type:< >- Icing:< >-
"""

remove_punc = str.maketrans(dict.fromkeys(string.punctuation, ' '))
print(str.translate(s, remove_punc))

这里对其他方法有一个很好的概述：

因此，您要替换的字符只有和-？我要替换序列中可能出现的任何标点符号。那么以下任何一项：！$%&\'*+，-./：@[\]^_`{|}~

s = """
Baking cake of straw-bana-choco will take longer than expcted
Please include as much of the following data that is available.< >< >- Cake Type:< >- Flavors:< >- Decoration Type:< >- Icing:< >-
"""

remove_punc = str.maketrans(dict.fromkeys(string.punctuation, ' '))
print(str.translate(s, remove_punc))

Baking cake of straw bana choco will take longer than expcted
Please include as much of the following data that is available         Cake Type      Flavors      Decoration Type      Icing
