efficient arrays of numeric data
array – arrays of numeric data
This module implements a subset of the corresponding CPython module, as described below. For more information, refer to the original CPython documentation: array.
Supported format codes: b, B, h, H, i, I, l,
L, q, Q, f, d (the latter 2 depending on the
floating-point support).
Classes
array.array
class array.array(typecode, [iterable])Create array with elements of given type. Initial contents of the array are given by iterable. If it is not provided, an empty array is created.
append
append(val)Append new element val to the end of array, growing it.
extend
extend(iterable)Append new elements as contained in iterable to the end of array, growing it.
__getitem__
__getitem__(index)Indexed read of the array, called as a[index] (where a is an array).
Returns a value if index is an int and an array if index is a slice.
Negative indices count from the end and IndexError is thrown if the index is
out of range.
Note: __getitem__ cannot be called directly (a.__getitem__(index) fails) and
is not present in __dict__, however a[index] does work.
__setitem__
__setitem__(index, value)Indexed write into the array, called as a[index] = value (where a is an array).
value is a single value if index is an int and an array if index is a slice.
Negative indices count from the end and IndexError is thrown if the index is out of range.
Note: __setitem__ cannot be called directly (a.__setitem__(index, value) fails) and
is not present in __dict__, however a[index] = value does work.
__len__
__len__()Returns the number of items in the array, called as len(a) (where a is an array).
Note: __len__ cannot be called directly (a.__len__() fails) and the
method is not present in __dict__, however len(a) does work.
__add__
__add__(other)Return a new array that is the concatenation of the array with other, called as
a + other (where a and other are both arrays).
Note: __add__ cannot be called directly (a.__add__(other) fails) and
is not present in __dict__, however a + other does work.
__iadd__
__iadd__(other)Concatenates the array with other in-place, called as a += other (where a and other
are both arrays). Equivalent to extend(other).
Note: __iadd__ cannot be called directly (a.__iadd__(other) fails) and
is not present in __dict__, however a += other does work.
__repr__
__repr__()Returns the string representation of the array, called as str(a) or repr(a)
(where a is an array). Returns the string "array(<type>, [<elements>])",
where <type> is the type code letter for the array and <elements> is a comma
separated list of the elements of the array.
Note: __repr__ cannot be called directly (a.__repr__() fails) and
is not present in __dict__, however str(a) and repr(a) both work.
