function

numpy.lib._datasource:DataSource.exists

source: /numpy/lib/_datasource.py :427

Signature

def   exists ( self ,  path )

Summary

Test if path exists.

Extended Summary

Test if path exists as (and in this order):

  • a local file.

  • a remote URL that has been downloaded and stored locally in the DataSource directory.

  • a remote URL that has not been downloaded, but is valid and accessible.

Parameters

path : str or pathlib.Path

Can be a local file or a remote URL.

Returns

out : bool

True if path exists.

Notes

When path is an URL, exists will return True if it's either stored locally in the DataSource directory, or is a valid remote URL. DataSource does not discriminate between the two, the file is accessible if it exists in either location.
