Pass Data to Python

When you pass MATLAB^® data as arguments to Python^®, MATLAB converts the data into types that best represent the data to the Python language.

MATLAB Input Argument Type — Scalar Values Only	Resulting Python `py.` Type
`double` `single`	`float`
Complex `single` Complex `double`	`complex`
`int8` `uint8` `int16` `uint16` `int32`	`int`
`uint32` `int64` `uint64`	`int` `long` (version 2.7 only)
`NaN`	`float(nan)`
`Inf`	`float(inf)`
`string` scalar `char` vector	`str`
`<missing>` value in `string`	`None`
`logical`	`bool`
Structure	`dict`
Python object — `py`.`type`	`type`
function handle `@py`.`module`.`function`, to Python functions only	`module`.`function`

MATLAB Input Argument Type — `1`-by-`N` Vector	Resulting Python Type
`double`	`array.array('d')`
`single`	`array.array('f')`
`int8`	`array.array('b')`
`uint8`	`array.array('B')`
`int16`	`array.array('h')`
`uint16`	`array.array('H')`
`int32`	`array.array('i')`
`uint32`	`array.array('I')`
`int64` (Not supported for Python 2.7 on Windows^®)	`array.array('q')`
`uint64` (Not supported for Python 2.7 on Windows)	`array.array('Q')`
`char` array containing values greater than 127 (version 2.7 only)	`unicode`
`char` vector `string` scalar	`str`
`cell` vector	`tuple`
