Solve the following python programming problem given the following code:
def _find_unused_static_warnings(filename, lines, ast_list) : 
    'Warn about unused static variables.' 
    static_declarations = dict (_get_static_declarations (ast_list)) 
    def find_variables_use(body) : 
        for child in body : 
            if (child.name in static_declarations) : 
                static_use_counts [child.name] += 1 
static_use_counts = collections.Counter () 
    for node in ast_list : 
        if (isinstance (node, ast.Function) and static_declarations.body) : 
            find_variables_use (node.body) 
else : 
            if (isinstance (node, ast.Class) and node.body) : 
                for child in node.body : 
                    if (isinstance (child, ast.Function) and child.body) : 
                        find_variables_use (child.body) 
count = 0 
    for (name, _) in sorted (static_declarations.items (), key = (lambda x : x [1].start)) : 
        if (not static_use_counts [name]) : 
            print ("{}:{}: unused variable '{}'".format (filename, lines.get_line_number (static_declarations [name].start), name)) 
            count += 1 
return count
