array

The array module defines a new object type, array, that works almost exactly like other sequence types, except that its contents are constrained to a single type. The type of an array is determined at the time of creation, using one of the following type codes:

Type Code	Description	C Type	Minimum Size (in Bytes)
‘c’	8-bit character	char	1
‘b’	8-bit integer	signed char	1
‘B’	8-bit unsigned integer	unsigned char	1
‘u’	Unicode character	PY_UNICODE	2 or 4
‘h’	16-bit integer	short	2
‘H’	16-bit unsigned integer	unsigned short	2
‘i’	Integer	int	4 or 8
‘I’	Unsigned integer	unsigned int	4 or 8
‘l’	Long integer	long	4 or 8
‘L’	Unsigned long integer	unsigned long	4 or 8
‘f’	Single-precision float	float	4
‘d’	Double-precision float	double	8

The representation of integers and long integers is determined ...
