numpy.DataSource.exists — NumPy v1.15 Manual (original) (raw)
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 theDataSource 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.
