numpy.DataSource.exists#

method

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
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.
