Pyextend Library-unpack List Collection string unpacking function

Pyextend-python Extend Lib

Unpack (iterable, Count, Fill=none)

Parameters:

Iterable: An iterative object that implements __ITER__, such as STR, tuple, dict, list

Count: The number that needs to be split, with an value greater than Len (iterable) followed by fill

Fill: Default Value padding

Examples of Use:

Example 1:        in['abc'        in[2]: A, B = unpack (source, 2)        in[  Print(A, b)        2:        in['abc'         in[2]: A, B, c, d = unpack (source, 4)        in[print(A, B, C, D)        a B None none< /c22>

Code:

@accepts (iterable='__iter__', count=int)defUnpack (iterable, Count, fill=None):"""The ITER data unpack function. """iterable=List (Enumerate (iterable)) CNT= CountifCount <= Len (iterable)ElseLen (iterable) Results= [Iterable[i][1] forIinchrange (CNT)]#Results[len (Results): Len (results)] = [Fill for i in range (count-cnt)]Results = merge (results, [fill forIinchRange (count-CNT)]) returnTuple (results)
