open vs opener: What are the differences?

<The comparison between 'open' and 'opener' functions in Python is detailed below:>

1. **Parameter Handling**: The 'open' function takes a file path as a mandatory argument, whereas the 'opener' function allows for customizing the behavior of opening the file.
2. **Functionality**: 'open' function is used to open a file and return a file object, while 'opener' function is used to create a custom opener instance which can be used with functions like 'urllib.request.build_opener'.
3. **Standard Usage**: 'open' function is commonly used for reading, writing, and appending to files, whereas 'opener' function is used more in advanced scenarios like defining custom URL opening logic.
4. **Error Handling**: Errors in file operations with 'open' function are typically handled using try-except blocks, whereas errors in custom opening behavior with 'opener' function might need to be handled within the custom opener instance.
5. **Compatibility**: The 'open' function is widely supported across Python versions and platforms, while the 'opener' function might have different implementations in various Python libraries, leading to compatibility issues in some cases.
6. **Flexibility**: The 'open' function offers a straightforward way to interact with files, while the 'opener' function provides a more flexible approach for defining how files should be opened and handled.

In Summary, the 'open' function in Python is primarily used for basic file handling operations, while the 'opener' function allows for customization and advanced file opening logic.
