numpy.DataSource.exists

method

DataSource.exists(self, path)

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

pathstr

Can be a local file or a remote URL.

Returns

outbool

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.
