The original content will be surrounded by triple percentage signs (%%%). Do not include the triple percentage signs in the translation.

### Technical terms in English

For technical terms in English that don't have a common translation term, use the original term in English.

### Content of code snippets

Do not translate the content of code snippets, keep the original in English. For example, `list`, `dict`, keep them as is.
