DataSource.exists()

numpy.DataSource.exists

DataSource.exists(path) [source]

Test if path exists.

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 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.
