How to remove the text crawled out by python3 crawlers xa0

The text content that the newbie crawled out of the novel website using lxml has these symbols. I want to ask how to remove them.

Answer 1

To remove line breaks and numbers from the Python 3 crawling text, you can use regular expressions to match and replace them. The specific steps were as follows:

1 Using the re module in Python 3 to match and replace text.

```python
import re
text = This is a line of text, another line of text.
pattern = r\n?\ s*[A-Za-z0-9_%+-]+\s*?
pattern_replaced = recompile(pattern)
result = pattern_replacedsub( text)
print(result)
```

Damage output:
```
This is a line
another row
text
```

Explanation: First, use the `<n?> in the re module. s*[A-Za-z0-9_%+-]+\s*?` To match the line break and the number. where `\n?` indicates whether or not a line break appears once `s*` indicates matching any character `[A-Za-z0-9_%+-]+` indicates matching any character `s*?` indicates matching any character `?` It indicated that a character was matched. Finally, use the sub function in the re module to replace the matching string with a new string and assign the new string to the variable result.

In Python 2, you can use the string method `replace()` to replace text.

```python
text = This is a line of text, another line of text.
text = textreplace(\n )replace( )
print(text)
```

Damage output:
```
This is a line
another row
text
```

Explanation: In Python 2, you use the string method `replace()` to replace all newline characters and numbers in the text to assign a new string to the variable `text`.
