It permits you to benefit from present context managers to mechanically deal with the setup and teardown phases everytime you’re coping with exterior assets or with operations that require these phases.
What’s a context supervisor? It’s a block of code that has unwanted side effects upon getting into and exiting. The context administration protocol permits you to create your individual context managers so you may customise the way in which you cope with system assets.
On this video course, you’ll be taught:
- How context managers work
- Some frequent context managers within the Python customary library
- How one can write a customized context supervisor
With this data, you’ll write extra expressive code and keep away from resource leaks in your packages.
