Give me a the Python program you requested given the following:
Complete the below
def indentedBlock(blockStatementExpr, indentStack, indent=True):

    ''''Helper method for defining space-delimited indentation blocks, such as
    those used to define block statements in Python source code.
    Parameters:
    - blockStatementExpr - expression defining syntax of statement that
    is repeated within the indented block
    - indentStack - list created by caller to manage indentation stack
    (multiple statementWithIndentedBlock expressions within a single grammar
    should share a common indentStack)
    - indent - boolean indicating whether block must be indented beyond the
    the current level.
set to False for block of left-most statements
    (default=C{True})
    A valid block must contain at least one C{blockStatement}.
    Example::
    data = \'\'\'
    def A(z):
    A1
    B = 100
    G = A2
    A2
    A3

    D
    def spam(x,y):
    def eggs(z):
    pass
    indentStack = [1]
    stmt = Forward()
    identifier = Word(alphas, alphanums)
    funcDecl = ("def" + identifier + Group( "(" + Optional( delimitedList(identifier) ) + ")" ) + ":")
    func_body = indentedBlock(stmt, indentStack)
    funcDef = Group( funcDecl + func_body )
    rvalue = Forward()
    funcCall = Group(identifier + "(" + Optional(delimitedList(rvalue)) + ")")
    rvalue << (funcCall | identifier | Word(nums))
    assignment = Group(identifier + "=" + rvalue)
    stmt << ( funcDef | assignment | identifier )
    module_body = OneOrMore(stmt)
    parseTree = module_body.parseString(data)
    parseTree.pprint()
    prints::
