Later you will see how **powerful** it can be.

/// tip

The fact that this is **standard Python** means that you will still get the **best possible developer experience** in your editor, with the tools you use to analyze and refactor your code, etc. ✨

And also that your code will be very compatible with many other Python tools and libraries. 🚀

En versiones previas de NodeJS / JavaScript en el Navegador, habrías usado "callbacks". Lo que lleva al "callback hell".

## Coroutines

	FileHeader
	zip          *Reader
	zipr         io.ReaderAt
	headerOffset int64 // includes overall ZIP archive baseOffset
	zip64        bool  // zip64 extended information extra field presence
}

// OpenReader will open the Zip file specified by name and return a ReadCloser.
//
// If any file inside the archive uses a non-local name
// (as defined by [filepath.IsLocal]) or a name containing backslashes

Dans les versions précédentes de Javascript NodeJS / Navigateur, vous auriez utilisé des "callbacks". Menant potentiellement à ce que l'on appelle le "callback hell".

   * each appears first in the source collection.

   * <p><b>Performance note:</b> This method will sometimes recognize that the actual copy operation

   * This reduces the expense of habitually making defensive copies at API boundaries. However, the

  // If a key hashes to 0x89abcdef the mask reduces it to 0x89abcdef & 0x7f == 0x6f. We'll call this
  // the "short hash".

  // The `keys`, `values`, and `entries` arrays always have the same size as each other. They can be
