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.
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()
typecode -- the typecode character used to create the array itemsize
-- the length in bytes of one array item
