Python in a Nutshell

Name

array

Synopsis

array(typecode,init='')

Creates and returns an array object a with the given typecode. init can be a plain string whose length is a multiple of itemsize; the string’s bytes, interpreted as machine values, directly initialize a’s items. Alternatively, init can be a list (of characters when typecode is 'c', otherwise of numbers): each item of the list initializes one item of a.

Array objects expose all the methods and operations of mutable sequences, as covered in Chapter 4, except method sort. Concatenation (with both + and extend) and assignment to slices require both operands to be arrays with the same type code (i.e., there is no implicit coercion between sequences). In addition to the methods of mutable sequences, an array object a also exposes the following methods.
