dbopen¶

class data_base.dbopen.dbopen(path, mode='r')¶

Context manager to open files in databases

This explicitly calls Python’s open() method on a file. This is generally not recommended, as the content of databases is usually written in a specific format, that is automatically inferred by the database.

However, for development and testing purposes, it may be of use to explicitly open these files.

Example

>>> with dbopen('db://my_db/my_key') as f:
...     print(f.read())
# dumps the raw file content - not recommended for e.g. binary formats

Parameters:¶

path : str¶

The path to the file.

mode : str¶

The mode in which the file is opened. Default: ‘r’

Attributes:¶

path¶

The path to the file.

Type:¶

str

mode¶

The mode in which the file is opened.

Type:¶

str

exit_hooks¶

A list of functions to be called when the context manager is exited. Used to close .tar files
