Converts a string to a URL-friendly slug.
|
|
|
|
- Use `str.lower()` and `str.strip()` to normalize the input string.
|
|
- Use `re.sub()` to to replace spaces, dashes and underscores with `-` and remove special characters.
|
|
|
|
```py
|
|
import re
|
|
|
|
def slugify(s):
|
|
s = s.lower().strip()
|
|
s = re.sub(r'[^\w\s-]', '', s)
|
|
s = re.sub(r'[\s_-]+', '-', s)
|
|
s = re.sub(r'^-+|-+$', '', s)
|
|
return s
|
|
```
|
|
|
|
```py
|
|
slugify('Hello World!') # 'hello-world'
|
|
```
