ArrayType = class array(__builtin__.object) |

array(typecode [, initializer]) -> array
Return a new array whose items are restricted by typecode, and
initialized from the optional initializer value, which must be a list,
string. or iterable over elements of the appropriate type.
Arrays represent basic values and behave very much like lists, except
the type of objects stored in them is constrained.
Methods:
append() -- append a new item to the end of the array
buffer_info() -- return information giving the current memory info
byteswap() -- byteswap all the items of the array
count() -- return number of occurences of an object
extend() -- extend array by appending multiple elements from an iterable
fromfile() -- read items from a file object
fromlist() -- append items from the list
fromstring() -- append items from the string
index() -- return index of first occurence of an object
insert() -- insert a new item into the array at a provided position
pop() -- remove and return item (default last)
read() -- DEPRECATED, use fromfile()
remove() -- remove first occurence of an object
reverse() -- reverse the order of the items in the array
tofile() -- write all items to a file object
tolist() -- return the array converted to an ordinary list
tostring() -- return the array converted to a string
write() -- DEPRECATED, use tofile()
Attributes:
typecode -- the typecode character used to create the array
itemsize -- the length in bytes of one array item

- fromunicode(ustr)
Extends this array with data from the unicode string ustr.
The array must be a type 'u' array; otherwise a ValueError

array. Also called as read.

Write all items (as machine values) to the file object f. Also called as
write.
- tolist(...)
- tolist() -> list
Convert array to an ordinary list with the same items.
- tostring(...)
- tostring() -> string
Convert the array to an array of machine values and return the string
representation.
- tounicode(...)

Convert the array to a unicode string. The array must be
a type 'u' array; otherwise a ValueError is raised. Use
array.tostring().decode() to obtain a unicode string from
an array of some other type.
- write(...)

Write all items (as machine values) to the file object f. Also called as
write.
