Commands:
2rows Print the contents of first and last row in each sheet
3rows Print the contents of first, second and last row in each sheet
bench Same as "show", but doesn't print -- for profiling
biff_count[1] Print a count of each type of BIFF record in the file
biff_dump[1] Print a dump (char and hex) of the BIFF records in the file
fonts hdr + print a dump of all font objects
hdr Mini-overview of file (no per-sheet information)
hotshot Do a hotshot profile run e.g. ... -f1 hotshot bench bigfile*.xls
labels Dump of sheet.col_label_ranges and ...row... for each sheet
name_dump Dump of each object in book.name_obj_list
names Print brief information for each NAME record
ov Overview of file
profile Like "hotshot", but uses cProfile
show Print the contents of all rows in each sheet
version[0] Print versions of xlrd and Python and exit
xfc Print "XF counts" and cell-type counts -- see code for details
[0] means no file arg
[1] means only one file arg i.e. no glob.glob pattern

# PyMySQL
This package contains a pure-Python MySQL and MariaDB client library, based on
[PEP 249](https://www.python.org/dev/peps/pep-0249/).
## Requirements
- Python -- one of the following:
- [CPython](https://www.python.org/) : 3.9 and newer
- [PyPy](https://pypy.org/) : Latest 3.x version
- MySQL Server -- one of the following:
- [MySQL](https://www.mysql.com/) LTS versions
- [MariaDB](https://mariadb.org/) LTS versions
## Installation
Package is uploaded on [PyPI](https://pypi.org/project/PyMySQL).
You can install it with pip:
$ python3 -m pip install PyMySQL
To use "sha256_password" or "caching_sha2_password" for authenticate,
you need to install additional dependency:
$ python3 -m pip install PyMySQL[rsa]
To use MariaDB's "ed25519" authentication method, you need to install
additional dependency:
$ python3 -m pip install PyMySQL[ed25519]
## Documentation
Documentation is available online: <https://pymysql.readthedocs.io/>
For support, please refer to the
[StackOverflow](https://stackoverflow.com/questions/tagged/pymysql).
## Example
The following examples make use of a simple table
``` sql
CREATE TABLE `users` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`email` varchar(255) COLLATE utf8_bin NOT NULL,
`password` varchar(255) COLLATE utf8_bin NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin
AUTO_INCREMENT=1 ;
```
``` python
import pymysql.cursors
# Connect to the database
connection = pymysql.connect(host='localhost',
user='user',
password='passwd',
database='db',
cursorclass=pymysql.cursors.DictCursor)
with connection:
with connection.cursor() as cursor:
# Create a new record
sql = "INSERT INTO `users` (`email`, `password`) VALUES (%s, %s)"
cursor.execute(sql, ('webmaster@python.org', 'very-secret'))
# connection is not autocommit by default. So you must commit to save
# your changes.
connection.commit()
with connection.cursor() as cursor:
# Read a single record
sql = "SELECT `id`, `password` FROM `users` WHERE `email`=%s"
cursor.execute(sql, ('webmaster@python.org',))
result = cursor.fetchone()
print(result)
```
This example will print:
``` python
{'password': 'very-secret', 'id': 1}
```

Compatibility warning: PEP-249 specifies that any modified
parameters must be returned. This is currently impossible
as they are only available by storing them in a server
variable and then retrieved by a query. Since stored
procedures return zero or more result sets, there is no
reliable way to get at OUT or INOUT parameters via callproc.
The server variables are named @_procname_n, where procname
is the parameter above and n is the position of the parameter
(from zero). Once all result sets generated by the procedure
have been fetched, you can issue a SELECT @_procname_0, ...
query using .execute() to get any OUT or INOUT values.
Compatibility warning: The act of calling a stored procedure
itself creates an empty result set. This appears after any
result sets generated by the procedure. This is non-standard
behavior with respect to the DB-API. Be sure to use nextset()
to advance through all result sets; otherwise you may get
disconnected.

xlrd is a library for reading data and formatting information from Excel
files in the historical ``.xls`` format.
.. warning::
This library will no longer read anything other than ``.xls`` files. For
alternatives that read newer file formats, please see http://www.python-excel.org/.
The following are also not supported but will safely and reliably be ignored:
* Charts, Macros, Pictures, any other embedded object, **including** embedded worksheets.
* VBA modules
* Formulas, but results of formula calculations are extracted.
* Comments
* Hyperlinks
* Autofilters, advanced filters, pivot tables, conditional formatting, data validation
Password-protected files are not supported and cannot be read by this library.
Quick start:
.. code-block:: bash
pip install xlrd
.. code-block:: python
import xlrd
book = xlrd.open_workbook("myfile.xls")
print("The number of worksheets is {0}".format(book.nsheets))
print("Worksheet name(s): {0}".format(book.sheet_names()))
sh = book.sheet_by_index(0)
print("{0} {1} {2}".format(sh.name, sh.nrows, sh.ncols))
print("Cell D30 is {0}".format(sh.cell_value(rowx=29, colx=3)))
for rx in range(sh.nrows):
print(sh.row(rx))
From the command line, this will show the first, second and last rows of each sheet in each file:
.. code-block:: bash
python PYDIR/scripts/runxlrd.py 3rows *blah*.xls

Open a spreadsheet file for data extraction.
:param filename: The path to the spreadsheet file to be opened.
:param logfile: An open file to which messages and diagnostics are written.
:param verbosity: Increases the volume of trace material written to the
logfile.
:param use_mmap:
Whether to use the mmap module is determined heuristically.
Use this arg to override the result.
Current heuristic: mmap is used if it exists.
:param file_contents:
A string or an :class:`mmap.mmap` object or some other behave-alike
object. If ``file_contents`` is supplied, ``filename`` will not be used,
except (possibly) in messages.
:param encoding_override:
Used to overcome missing or bad codepage information
in older-version files. See :doc:`unicode`.
:param formatting_info:
The default is ``False``, which saves memory.
In this case, "Blank" cells, which are those with their own formatting
information but no data, are treated as empty by ignoring the file's
``BLANK`` and ``MULBLANK`` records.
This cuts off any bottom or right "margin" of rows of empty or blank
cells.
Only :meth:`~xlrd.sheet.Sheet.cell_value` and
:meth:`~xlrd.sheet.Sheet.cell_type` are available.
When ``True``, formatting information will be read from the spreadsheet
file. This provides all cells, including empty and blank cells.
Formatting information is available for each cell.
Note that this will raise a NotImplementedError when used with an
xlsx file.
:param on_demand:
Governs whether sheets are all loaded initially or when demanded
by the caller. See :doc:`on_demand`.
:param ragged_rows:
The default of ``False`` means all rows are padded out with empty cells so
that all rows have the same size as found in
:attr:`~xlrd.sheet.Sheet.ncols`.
``True`` means that there are no empty cells at the ends of rows.
This can result in substantial memory savings if rows are of widely
varying sizes. See also the :meth:`~xlrd.sheet.Sheet.row_len` method.
:param ignore_workbook_corruption:
This option allows to read corrupted workbooks.
When ``False`` you may face CompDocError: Workbook corruption.
When ``True`` that exception will be ignored.
:returns: An instance of the :class:`~xlrd.book.Book` class.
