How to calculate the absolute path from a relative path and a base directory using the path package?

To calculate the absolute path from a relative path and a base directory using the path package in Python, you can follow the steps below:

Import the path module from the pathlib package:

from pathlib import Path

Use the Path class to create a Path object for the base directory:

base_directory = Path('/path/to/base/directory')

Create a Path object for the relative path:

relative_path = Path('relative/path/to/file')

Use the resolve() method of the Path object to calculate the absolute path:

absolute_path = base_directory.resolve() / relative_path

The resolve() method resolves any symbolic links and returns the absolute path of the directory or file. The / operator is used to concatenate the base directory and relative path, resulting in the absolute path.

Here's the complete example:

from pathlib import Path

base_directory = Path('/path/to/base/directory')
relative_path = Path('relative/path/to/file')

absolute_path = base_directory.resolve() / relative_path
print(absolute_path)

Make sure to replace /path/to/base/directory with the actual base directory path, and relative/path/to/file with the desired relative path.
