Usługi przetwarzania tekstu

Moduły opisane w tym rozdziale dostarczają szeroki zakres operacji i innych usług, pozwalających na manipulowanie ciągami znaków.

The codecs module described under Binary Data Services is also highly relevant to text processing. In addition, see the documentation for Python’s built-in string type in Text Sequence Type — str.
