'utf-8' codec can't decode byte 0xba in position 21: invalid start byte

这个错误通常是因为在使用UTF-8编码时,出现了非法的字节序列。这可能是因为文件本身不是UTF-8编码,或者文件中包含了不符合UTF-8编码规则的字符。解决这个问题的方法有以下几种:
1. 指定正确的编码方式:在读取文件时,指定正确的编码方式,例如:
```python
with open('file.txt', 'r', encoding='utf-8') as f:
# do something
```
2. 使用其他编码方式:如果文件确实不是UTF-8编码,可以尝试使用其他编码方式打开文件,例如:
```python
with open('file.txt', 'r', encoding='gbk') as f:
# do something
```
3. 处理非法字符:如果文件中包含了不符合UTF-8编码规则的字符,可以尝试使用Python内置的`codecs`模块处理这些字符,例如:
```python
import codecs
with codecs.open('file.txt', 'r', encoding='utf-8', errors='ignore') as f:
# do something
```
这里的`errors='ignore'`表示忽略非法字符。

utf-8 codec can't decode byte 0xba in position 115: invalid start byte
This error usually occurs when there is an issue with decoding a byte sequence using the UTF-8 codec. The byte 0xba indicates that there might be a non-UTF-8 character in the input string.
To resolve this issue, you can try the following steps:
1. Check the encoding of the input source: Ensure that the source of the input data is encoded using UTF-8. If it's encoded using a different encoding, you will need to decode it using the appropriate codec before processing it.
2. Handle encoding errors: If you expect non-UTF-8 characters in the input string, you can handle the decoding error by specifying the `errors` parameter when decoding the byte sequence. Common error handling options include `'ignore'`, `'replace'`, or `'backslashreplace'`.
Here's an example of how you can handle the error and decode the byte sequence:
```python
byte_sequence = b'\xba'
try:
decoded_string = byte_sequence.decode('utf-8')
print(decoded_string)
except UnicodeDecodeError as e:
print(f"Error decoding byte sequence: {e}")
```
Remember to replace `byte_sequence` with your actual byte sequence.
By handling the error or ensuring proper encoding, you should be able to resolve the `utf-8 codec can't decode byte` issue.
爬取网页源码(unicode error) utf-8 codec can t decode byte 0xba in position 4: invalid start byte
您好!对于遇到 Unicode 错误的问题,一般是由于网页源码中包含无法解码的字符导致的。解决这个问题的一种方法是使用合适的编码方式进行解码。
在您的情况下,错误消息中提到无法解码字节 0xba,这可能表示该字节不是以 UTF-8 编码格式存储的。您可以尝试使用其他编码方式,如 Latin-1(也称为 ISO-8859-1)进行解码。下面是一个示例代码:
```python
import requests
url = "待爬取的网页地址"
# 发起请求获取网页内容
response = requests.get(url)
# 使用 Latin-1 编码进行解码
content = response.content.decode('latin-1')
# 打印网页内容
print(content)
```
在上述代码中,我们使用了 `requests` 库发起请求获取网页内容,并使用 `latin-1` 编码对内容进行解码。您可以根据实际情况修改代码中的网页地址以及解码方式。希望这能帮助到您!如果您还有其他问题,请随时提问。
