## Parser configuration in all fetchers
All fetchers share the same import method, as you will see in the upcoming pages
```python
>>> from scrapling.fetchers import Fetcher, AsyncFetcher, StealthyFetcher, DynamicFetcher
from scrapling.fetchers import Fetcher, AsyncFetcher, StealthyFetcher, DynamicFetcher
```
Then you use it right away without initializing like this, and it will use the default parser settings:
```python
>>> page = StealthyFetcher.fetch('https://example.com')
page = StealthyFetcher.fetch('https://example.com')
```
If you want to configure the parser ([Selector class](parsing/main_classes.md#selector)) that will be used on the response before returning it for you, then do this first:
```python
>>> from scrapling.fetchers import Fetcher
>>> Fetcher.configure(adaptive=True, keep_comments=False, keep_cdata=False) # and the rest
from scrapling.fetchers import Fetcher
Fetcher.configure(adaptive=True, keep_comments=False, keep_cdata=False) # and the rest
```
or
```python
>>> from scrapling.fetchers import Fetcher
>>> Fetcher.adaptive=True
>>> Fetcher.keep_comments=False
>>> Fetcher.keep_cdata=False # and the rest
from scrapling.fetchers import Fetcher
Fetcher.adaptive=True
Fetcher.keep_comments=False
Fetcher.keep_cdata=False # and the rest
```
