numpy.DataSource.exists¶

DataSource.exists(path)[source]¶

Test if path exists.

Test ifpath exists as (and in this order):

• a local file.
• a remote URL that has been downloaded and stored locally in theDataSource directory.
• a remote URL that has not been downloaded, but is valid andaccessible.

Parameters:	path : str Can be a local file or a remote URL.
Returns:	out : bool True ifpath exists.

Notes

Whenpath is an URL,exists will return True if it’s eitherstored locally in theDataSource directory, or is a valid remoteURL.DataSource does not discriminate between the two, the fileis accessible if it exists in either location.
