Get file handle for given path/buffer and mode.
|
|
Parameters
|
----------
|
path_or_buf : str or file handle
|
File path or object.
|
mode : str
|
Mode to open path_or_buf with.
|
encoding : str or None
|
Encoding to use.
|
{compression_options}
|
|
May be a dict with key 'method' as compression mode
|
and other keys as compression options if compression
|
mode is 'zip'.
|
|
Passing compression options as keys in dict is
|
supported for compression modes 'gzip', 'bz2', 'zstd' and 'zip'.

|
is_text : bool, default True
|
Whether the type of the content passed to the file/buffer is string or
|
bytes. This is not the same as `"b" not in mode`. If a string content is
|
passed to a binary file/buffer, a wrapper is inserted.
|
errors : str, default 'strict'
|
Specifies how encoding and decoding errors are to be handled.
|
See the errors argument for :func:`open` for a full list

Rename column names if duplicates exist.
|
|
Currently the renaming is done by appending a period and an autonumeric,
|
but a custom pattern may be supported in the future.
|
|
Examples
|
--------
|
>>> dedup_names(["x", "y", "x", "x"], is_potential_multiindex=False)
|
['x', 'y', 'x.1', 'x.2']
