utf8bom转utf8 python

可以使用Python内置的io模块来实现utf8bom转utf8的操作。示例代码如下:
```python
import io
with open('your_file_with_utf8bom.txt', 'r', encoding='utf-8-sig') as f:
content = f.read()
with open('output_file_utf8.txt', 'w', encoding='utf-8') as f:
f.write(content)
```
其中,`your_file_with_utf8bom.txt`是包含utf8bom编码的文件名,`output_file_utf8.txt`是输出文件名,可以根据你的需要自行修改。在读取文件时,使用`utf-8-sig`编码,这样可以去除文件中的utf8bom。在写入文件时,使用`utf-8`编码,这样就可以将文件以utf8编码写入到输出文件中。

UTF-8 bom的作用
UTF-8 BOM (Byte Order Mark) is a special character used to indicate the encoding of a text file as UTF-8. It is placed at the beginning of the file and is not typically displayed to the user.
The main purpose of the UTF-8 BOM is to allow software to automatically detect the encoding of a text file and handle it appropriately. This can be especially important in multi-lingual environments, where different files may use different encodings. By including a BOM, software can quickly determine the encoding and process the text correctly.
However, not all software supports the UTF-8 BOM and in some cases it may cause problems. For example, some text editors may display the BOM as a special character at the beginning of the file. Additionally, some programming languages, such as Python, do not expect the BOM and may raise an error if it is present.
In general, it is recommended to only use the UTF-8 BOM in cases where it is specifically needed or required by the software being used.
python print utf-8-sig
在Python中,print函数用于将文本或其他数据输出到控制台。而utf-8-sig是一种特殊的UTF-8编码格式,它在文件开头添加了一个字节顺序标记(BOM),用于指示文件的编码方式。
当我们使用print函数输出文本时,默认情况下,Python会将文本以UTF-8编码方式进行输出。但是,如果文本中包含特殊字符或者非ASCII字符,可能会导致控制台无法正确显示这些字符。
为了解决这个问题,可以使用utf-8-sig编码格式来输出文本。这种编码格式会在UTF-8编码的基础上添加一个BOM,以帮助控制台正确解析和显示特殊字符或非ASCII字符。
下面是一个使用utf-8-sig编码格式输出文本的示例:
```python
text = "你好,世界!"
print(text.encode("utf-8-sig").decode("utf-8"))
```
这样就可以确保控制台正确显示包含特殊字符或非ASCII字符的文本。
