Solve the following python programming problem given the following code:
def _count_function(self, indent_level = 1) : 
    indent = ('    ' * indent_level) 
    def _end_of_function(line) : 
        return ((line != '') and (not line.startswith (indent)) and (not line.startswith ('#'))) 
start_pos = self.pos 
    while (self.pos < self.n) : 
        line = self.lines [self.pos] 
        if _end_of_function (line) : 
            self._push_count (start_pos) 
            return 
self.pos += 1 
        if _is_def_line (line) : 
            self._count_function (indent_level = (start_pos + 1)) 
self._push_count (start_pos) 

    
    

    Fix the buggy line: self._count_function (indent_level = (start_pos + 1))

#Here is Python program to fix the buggy line: self.

self._count_function (indent_level = (indent_level + 1))
