find_by_date
(date, root_path, path_fmt, fn_pattern, fn_ext, timestep, num_prev_files=0, num_next_files=0)¶ List input files whose timestamp matches the given date.
Parameters: - date : datetime.datetime
The given date.
- root_path : str
The root path to search the input files.
- path_fmt : str
Path format. It may consist of directory names separated by ‘/’, date/time specifiers beginning with ‘%’ (e.g. %Y/%m/%d) and wildcards (?) that match any single character.
- fn_pattern : str
The name pattern of the input files without extension. The pattern can contain time specifiers (e.g. %H, %M and %S).
- fn_ext : str
Extension of the input files.
- timestep : float
Time step between consecutive input files (minutes).
- num_prev_files : int
Optional, number of previous files to find before the given timestamp.
- num_next_files : int
Optional, number of future files to find after the given timestamp.
Returns: - out : tuple
If num_prev_files=0 and num_next_files=0, return a pair containing the found file name and the corresponding timestamp as a datetime.datetime object. Otherwise, return a tuple of two lists, the first one for the file names and the second one for the corresponding timestemps. The lists are sorted in ascending order with respect to timestamp. A None value is assigned if a file name corresponding to a given timestamp is not found.
